Abstract

In this document, the Federal Communications Commission (the FCC or Commission) proposes rules that would help ensure that emerging Next Generation 911 (NG911) networks are reliable and interoperable. NG911 is replacing legacy 911 technology across the country with Internet Protocol (IP)-based infrastructure that will support new 911 capabilities, including text, video, and data. However, for NG911 to be fully effective, NG911 networks must safeguard the reliability of critical components and support the interoperability needed to seamlessly transfer 911 calls and data from one network to another. When the Commission first adopted 911 reliability rules in 2013, the transition to NG911 was in its very early stages. Since then, many state and local 911 Authorities have made significant progress in deploying NG911 capabilities in their jurisdictions. This Further Notice of Proposed Rulemaking (FNPRM) is the next step in fulfilling the Commission's commitment to facilitate the NG911 transition and to ensure that the transition does not inadvertently create vulnerabilities in the nation's critical public safety networks. The FNPRM proposes to update the definition of "covered 911 service provider" in the Commission's existing 911 reliability rules to ensure that the rules apply to service providers that control or operate critical pathways and components in NG911 networks. It also proposes to update the reliability standards for providers of critical NG911 functions to ensure the reliable delivery of 911 traffic to NG911 delivery points, and proposes to establish NG911 interoperability requirements for interstate transfer of 911 traffic between Emergency Services IP Networks (ESInets). In addition, the FNPRM proposes to modify the certification and oversight mechanisms in the current 911 reliability rules to improve reliability and interoperability in NG911 systems while minimizing burdens on service providers, and proposes to empower state and local 911 Authorities to obtain reliability and interoperability certifications directly from covered 911 service providers.

Facilitating Implementation of Next Generation 911 Services 
(NG911); Improving 911 Reliability

AGENCY: Federal Communications Commission.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: In this document, the Federal Communications Commission (the 
FCC or Commission) proposes rules that would help ensure that emerging 
Next Generation 911 (NG911) networks are reliable and interoperable. 
NG911 is replacing legacy 911 technology across the country with 
Internet Protocol (IP)-based infrastructure that will support new 911 
capabilities, including text, video, and data. However, for NG911 to be 
fully effective, NG911 networks must safeguard the reliability of 
critical components and support the interoperability needed to 
seamlessly transfer 911 calls and data from one network to another. 
When the Commission first adopted 911 reliability rules in 2013, the 
transition to NG911 was in its very early stages. Since then, many 
state and local 911 Authorities have made significant progress in 
deploying NG911 capabilities in their jurisdictions. This Further 
Notice of Proposed Rulemaking (FNPRM) is the next step in fulfilling 
the Commission's commitment to facilitate the NG911 transition and to 
ensure that the transition does not inadvertently create 
vulnerabilities in the nation's critical public safety networks. The 
FNPRM proposes to update the definition of ``covered 911 service 
provider'' in the Commission's existing 911 reliability rules to ensure 
that the rules apply to service providers that control or operate 
critical pathways and components in NG911 networks. It also proposes to 
update the reliability standards for providers of critical NG911 
functions to ensure the reliable delivery of 911 traffic to NG911 
delivery points, and proposes to establish NG911 interoperability 
requirements for interstate transfer of 911 traffic between Emergency 
Services IP Networks (ESInets). In addition, the FNPRM proposes to 
modify the certification and oversight mechanisms in the current 911 
reliability rules to improve reliability and interoperability in NG911 
systems while minimizing burdens on service providers, and proposes to 
empower state and local 911 Authorities to obtain reliability and 
interoperability certifications directly from covered 911 service 
providers.

Synopsis

Introduction

    In this Further Notice of Proposed Rulemaking (FNPRM), we propose 
to update existing Commission rules to ensure the resiliency, 
reliability, interoperability, and accessibility of Next Generation 911 
(NG911) networks. With the transition to NG911, dedicated 911 networks 
are evolving from Time Division Multiplexing (TDM)-based architectures 
to Internet Protocol (IP)-based architectures, which will provide state 
and local 911 authorities with significant new capabilities to respond 
to those in need of emergency assistance and to improve system 
resilience in comparison to legacy 911. These new capabilities include 
multimedia NG911 calls that allow the transmission of texts, photos, 
videos, and data, which persons with disabilities depend on for full 
and equal access to emergency services. However, for NG911 to be fully 
effective and accessible, it is essential that NG911 networks are 
designed to ensure the reliability of critical components and 
applications and interoperability to enable seamless transfer of 911 
calls and data.
    Today, we propose certain reliability and interoperability 
requirements that would apply to ``covered 911 service providers'' 
(CSPs), the providers that support essential functions within 911 
networks such as call routing and automatic caller location, with 
particular emphasis on entities that provide these capabilities in the 
NG911 environment.\1\ Our proposals build on the 911 reliability rules 
that the Commission adopted in 2013, which require CSPs to take 
measures to provide reliable 911 service to Public Safety Answering 
Points (PSAPs) with respect to circuit diversity, central-office backup 
power, and diverse network monitoring.\2\ We propose to modify and 
update these rules to keep pace with the ongoing transition to NG911, 
improve NG911 network reliability and resilience, reduce the risk of 
outages, and ensure accessibility to the life-saving improvements that 
NG911 is uniquely capable of delivering. We also propose to adopt rules 
that would require Emergency Services IP Network (ESInet) providers to 
support interoperability in the interstate transfer of 911 calls and 
data, which will strengthen the ability of state and local 911 
Authorities to ensure continued access to NG911 services during major 
emergencies by deploying resources in support of one another.\3\
---------------------------------------------------------------------------

    \1\ See 47 CFR 9.19(a)(4) (defining a CSP as any entity that (A) 
``[p]rovides 911, E911, or NG911 capabilities such as call routing, 
automatic location information (ALI), automatic number 
identification (ANI), or the functional equivalent of those 
capabilities, directly to a [PSAP] . . . ; and/or (B) [o]perates one 
or more central offices that directly serve a PSAP'').
    \2\ See 47 CFR 9.19; Improving 911 Reliability; Reliability and 
Continuity of Communications Networks, Including Broadband 
Technologies, PS Docket Nos. 13-75 and 11-60, Report and Order, 28 
FCC Rcd 17476, 17477-78, paras. 2-5 (2013), 79 FR 3123 (Jan. 17. 
2014) (911 Reliability Order); FCC Public Safety and Homeland 
Security Bureau, Impact of the June 2012 Derecho On Communications 
Networks and Services: Report and Recommendations at 1-2 (2013) 
(Derecho Report), <a href="http://www.fcc.gov/document/derecho-report-and-recommendations">http://www.fcc.gov/document/derecho-report-and-recommendations</a>. PSAP refers to ``[a]n answering point that has been 
designated to receive 911 calls and route them to emergency services 
personnel.'' 47 CFR 9.3.
    \3\ An ESInet is ``[a]n internet Protocol (IP)-based network 
that is managed or operated by a 911 Authority or its agents or 
vendors and that is used for emergency services communications, 
including Next Generation 911.'' 47 CFR 9.28. A ``911 Authority'' is 
a ``State, territorial, regional, Tribal, or local governmental 
entity that operates or has administrative authority over all or any 
aspect of a communications network for the receipt of 911 traffic at 
NG911 Delivery Points and for the transmission of such traffic from 
that point to PSAPs.'' Id.
---------------------------------------------------------------------------

    It is particularly important that we take action on these issues 
now. When the Commission adopted the current 911 reliability rules in 
2013, the transition to NG911 was in its very early stages. However, as 
the Commission observed in its July 2024 NG911 Transition Order, the 
NG911 transition has now progressed to the point that most states have 
invested in NG911 technology, and many states and local jurisdictions 
have operating ESInets.\4\ Moreover, many public safety commenters in 
the NG911 Transition proceeding expressed strong support for the 
Commission taking further action to strengthen NG911 reliability, 
interoperability, and accessibility. Finally, while NG911 has inherent 
reliability and accessibility advantages over legacy 911, our 
experience with recent outages affecting 911 suggests that some 
critical elements of NG911 networks may not be adequately covered by 
our existing 911 reliability rules. To address these issues, we propose 
and seek comment on the following measures:
---------------------------------------------------------------------------

    \4\ Facilitating Implementation of Next Generation 911 Services 
(NG911); Location-Based Routing for Wireless 911 Calls, PS Docket 
Nos. 21-479 and 18-64, Report and Order, FCC 24-78, 2024 WL 3507091 
at *12, para. 29 (Jul. 19, 2024), 89 FR 78066 (Oct. 17, 2024) (NG911 
Transition Order).
---------------------------------------------------------------------------

    <bullet> Covered 911 Service Providers. First, we propose to update 
the definition of ``covered service provider'' in the Commission's 
existing 911 reliability rules to specify how the rules apply to 
service providers that control or operate critical pathways and 
components of NG911 networks.
    [cir] The current CSP definition focuses on providers of certain 
network facilities and capabilities that are specific to legacy 911 
systems and states that the rules also apply to their ``functional 
equivalents'' in the NG911 environment. We propose to specify that 
certain critical NG911 facilities and capabilities (e.g., Location 
Validation Functions (LVFs), Geographic Information Systems (GISs), 
Emergency Call Routing Functions (ECRFs), Emergency Services Routing 
Proxies (ESRPs), and Policy Routing Functions (PRFs)) are among the 
functional equivalents referred to in the current rule and that 
providers of these capabilities therefore fall within the definition of 
CSPs.
    [cir] We also propose to expand the CSP definition to encompass the 
following types of providers of critical connectivity in the NG911 
environment: (1) operators of Location Information Servers (LISs) or 
equivalent IP 911 location databases; (2) operators of Legacy Network 
Gateways (LNGs); (3) operators of interstate Major Transport Facilities 
that meet or exceed Optical Carrier 3 (OC3) capacity and carry 911 
traffic from multiple OSPs for ultimate delivery to NG911 Delivery 
Points or ESInets; (4) operators of IP Traffic Aggregation Facilities 
that carry segregated 911 traffic from multiple OSPs towards ultimate 
transmission to an NG911 Delivery Point or ESInet; and (5) operators of 
interstate interconnecting facilities between ESInets.\5\
---------------------------------------------------------------------------

    \5\ OSPs are ``[p]roviders that originate 911 traffic, 
specifically wireline providers; commercial mobile radio service 
(CMRS) providers, excluding mobile satellite service (MSS) operators 
to the same extent as set forth in Sec.  9.10(a); covered text 
providers, as defined in Sec.  9.10(q)(1); interconnected Voice over 
internet Protocol (VoIP) providers, including all entities subject 
to subpart D of this part; and internet-based Telecommunications 
Relay Service (TRS) providers that are directly involved with 
routing 911 traffic, pursuant to subpart E of this part.'' 47 CFR 
9.28. The term ``911 traffic'' means ``[t]ransmissions consisting of 
all 911 calls (as defined in Sec. Sec.  9.3, 9.11(b)(2)(ii)(A), 
9.14(d)(2)(iii)(A), and 9.14(e)(2)(ii)(A)) and/or 911 text messages 
(as defined in Sec.  9.10(q)(9)), as well as information about 
calling parties' locations and originating telephone numbers and 
routing information transmitted with the calls and/or text 
messages.'' Id.
---------------------------------------------------------------------------

    <bullet> Reliability Standards. Second, we propose to update the 
reasonable reliability standards that providers of critical NG911 
functions must employ to ensure the reliable delivery of 911 traffic to 
NG911 delivery points. We believe such action is needed to ensure the 
reliability of critical transport, aggregation, and data facilities in 
the NG911 ecosystem at the interstate and national level and the 
accessibility of NG911 services.

[[Page 23770]]

    <bullet> Interoperability. Third, we propose to establish NG911 
interoperability requirements for interstate transfer of 911 traffic 
between ESInets to optimize PSAP call transfer capabilities during 
service disruptions. We seek to ensure that PSAPs can transfer calls to 
nearby PSAPs located across state borders with minimal need for the 
traffic to be retranslated or reformatted in order for such transfers 
to occur. We further propose to harmonize this action with our current 
911 reliability certification rules by adding an interoperability 
certification to the rules. We also seek updated information on 
interstate interoperability by type of service, with particular 
emphasis on services used by consumers, including those with 
accessibility needs.
    <bullet> Oversight. Finally, we propose to modify the certification 
and oversight mechanisms in our 911 reliability rules to improve 
implementation of reliability and interoperability in NG911 systems. 
Additionally, we propose to enable state and local 911 Authorities to 
obtain reliability and interoperability certifications directly from 
CSPs, so that 911 Authorities can more easily exercise their existing 
authority to address reliability, interoperability, and accessibility 
needs within their jurisdictions.
    Together, these proposals are intended to improve transparency and 
accountability during the NG911 transition and help ensure that the 
nation's 911 system functions effectively and reliably. We believe that 
these proposals will make the nation's 911 service more accessible, 
reliable and interoperable, while striking an appropriate balance 
between costs and benefits of such regulation. We seek comment on the 
tentative conclusions, proposals, and analyses set forth in this FNPRM, 
as well as on any alternative approaches.

Background

A. 911 Reliability Framework

    The Commission adopted certain, specific 911 reliability rules for 
``covered 911 service providers'' or CSPs in 2013 following the 
devastating impact on 911 services of the June 2012 mid-Atlantic 
derecho storm.\6\ In the 2013 911 Reliability Order, the Commission 
determined that the reliability, resiliency, and availability of 911 
service could be improved through implementation of network reliability 
practices and other sound engineering principles, and it accordingly 
adopted 911 reliability certification rules for CSPs.\7\ CSPs are 
entities that provide 911, E911, or NG911 capabilities such as call 
routing, automatic location information (ALI), automatic number 
identification (ANI), or the functional equivalent of those 
capabilities, directly to a PSAP, statewide default answering point, or 
appropriate local emergency authority.\8\ The rules mandate that all 
CSPs ``shall take reasonable measures to provide reliable 911 service 
with respect to circuit diversity, central-office backup power, and 
diverse network monitoring.'' \9\ To demonstrate that they are taking 
such reasonable measures, the rules require CSPs to annually certify 
that they have ``perform[ed] all the specific certification elements 
outlined in our rules regarding 911 circuit auditing, backup power at 
central offices that directly service PSAPs, and diverse network 
monitoring links.'' \10\ CSPs may also meet these certification 
requirements by showing that they have implemented ``alternative 
measures . . . that are reasonably sufficient to mitigate the risk of 
failure, or that one or more certification elements are not applicable 
to its network.'' \11\ In addition, CSPs must notify PSAPs of network 
outages that may affect the PSAPs' ability to receive 911 calls.\12\ 
The Commission delegated authority to the Bureau ``to order appropriate 
remedial action on a case-by-case basis where 911 reliability 
certifications indicate such actions are necessary to protect public 
safety.'' \13\

sometimes refer herein to PSAPs, statewide default answering points,

include PSAPs or governmental authorities to the extent they provide 
911 capabilities or entities that offer the capability to originate 
911 calls where another service provider delivers those calls and 
associated number or location information to the appropriate PSAP.

the Commission's rules, CSPs may implement and certify an 
alternative measure for any of the specific 911 certification 
elements, as long as the certification includes an explanation of 
how such alternative measures are reasonably sufficient to mitigate 
the risk of failure).

providers, and interconnected voice over internet protocol providers 
to transmit all 911 calls to PSAPs. See 47 CFR 9.4, 9.10(b), 
9.11(b).
---------------------------------------------------------------------------

    Since the adoption of the 911 reliability rules in 2013, the 
Commission has revisited the rules on several occasions, but has not 
updated them to account for the transition to NG911. In 2014, the 
Commission issued a Policy Statement and NPRM on improving 911 
governance and reliability, which reaffirmed the importance of 911 
reliability and posited that changes in 911 technologies and a recent 
series of ``sunny day'' 911 outages indicated a potential need for 
further action.\14\ Among the proposals advanced in the NPRM, the 
Commission sought comment on whether to broaden the definition of CSPs 
in former Sec.  12.4 (now Sec.  9.19).\15\

2014 Reliability NPRM, we incorporate comments filed in response to 
the NPRM into today's item.

    In 2015, the Commission issued a Reconsideration Order finding that 
the network reliability certification framework adopted in the 2013 911 
Reliability Order was intended to allow flexibility for all CSPs to 
rely on reasonable alternative measures in lieu of any of the 
enumerated reliability practices set forth in former Sec.  12.4(c) (now 
Sec.  9.19(c)) of the rules, and that such flexibility was specifically 
intended to apply to the transition to NG911.\16\ The Commission stated 
that ``flexibility is essential to support and encourage the transition 
to NG911'' and pointed out that, in the 911 Reliability Order, the 
Commission stated that ``we intend today's rules to apply to current

B. 911 Reliability Practices and CSRIC Recommendations

    In 2018, the Bureau disseminated lessons learned from major network 
outages and reminded and encouraged communications service providers to 
review industry best practices to ensure network reliability.\20\ The 
Bureau created a new network reliability page (<a href="http://www.fcc.gov/network-reliability-resources">http://www.fcc.gov/network-reliability-resources</a>) to help ensure that network providers, 
public safety entities, and the general public can readily access the 
Bureau's work in promoting industry best practices.\21\ Based on the 
Bureau's analysis of several major network outages that affected 
subscribers, including those calling 911 for emergency assistance, the 
Bureau staff determined that providers could have likely prevented or 
mitigated the outages by employing certain network reliability best 
practices.\22\ The Bureau encouraged communications service providers 
to implement certain industry best practices, as previously recommended 
by the Commission's Communications Security, Reliability and 
Interoperability Council (CSRIC),\23\ including practices that could 
prevent or mitigate similar outages in the future.\24\

    In 2019, in anticipation of additional entities transitioning to 
NG911, CSRIC VI issued a report and recommendations for 911 system 
reliability and resiliency.\25\ The recommendations included measures 
to improve both legacy 911 and NG911, including ways in which the 
Commission could further the NG911 transition and enhance the 
reliability and effectiveness of NG911 through routing redundancy, 
maintenance, and mitigation of the threat of outages in both legacy 911 
and NG911 systems.\26\ The CSRIC recommendations address the need for 
service providers to (1) monitor for events resulting in loss of 
service; \27\ (2) understand points of failure risks to (a) call 
delivery, (b) location delivery, and (c) callback information; \28\ and 
(3) consider incorporating network detection tools and working with 
stakeholders to share information.\29\ CSRIC VI also developed and 
recommended action for modifying or adding best practices regarding 
overall monitoring, reliability, notifications, and accountability in 
preventing 911 outages in transitional NG911 environments \30\ as well 
as addressing cybersecurity considerations.\31\

    In 2020, the Bureau updated the CSRIC Best Practices database.\32\ 
The Bureau noted that CSRIC VII \33\ unanimously approved an update to 
the database to include best practices from CSRIC VI (addressing 
communications network security, emergency preparedness, and disaster 
recovery) as well as the deletion of best practices that had become 
obsolete. The Bureau reminded and encouraged communications service 
providers to follow industry best practices to ensure network 
reliability, consistent with the CSRIC's recommendations, including 
ensuring (1) sufficient circuit diversity and alternative routing of 
911 calls; (2) validating network changes in test environment, (3) 
using virtual interfaces and network management controls, and (4) 
making spare equipment available.\34\

C. 911 Interoperability

    While the Commission has not to date adopted rules relating to 911 
interoperability, in 2019, it directed CSRIC VII to survey the state of 
interoperability for the nation's 911 systems, including for legacy 
911,

[[Page 23772]]

transitional 911, and NG911 networks.\35\ In 2020, CSRIC VII Working 
Group 4 issued its report and recommendation on 911 interoperability, 
which were adopted by CSRIC VII. The report observed that 911 systems 
are highly interconnected, and interoperability between call-taking and 
call processing components is critical.\36\ In addition, the report 
noted that ``[l]egacy, transitioning, and fully NG911-capable systems 
capture and exchange potentially large amounts of data and transferring 
such data between 9-1-1 systems potentially requires external data 
connections.'' \37\ The report concluded that the state of national 
NG911 interoperability was highly dependent on the degree of progress 
made by state and local 911 authorities in transitioning their 
respective systems to mature or end-state NG911 capability.\38\ The 
report identified interoperability challenges and indicators of 
successful interoperability, and recommended that the U.S. ``continue 
to move forward with the deployment of NG9-1-1, with a strong focus on 
achieving interoperability, as defined in this report, which includes 
industry standards-based solutions.'' \39\

the jurisdictional and nation-wide ``end states'' of NG911 service. 
Per TFOPA, ``End State'' refers to the state in which PSAPs have 
evolved to become emergency communications centers (ECCs); are 
served by standards-based NG911 systems and/or elements; OSPs are 
providing SIP interfaces with location information during call 
setup; and ESInets are interconnected providing interoperability on 
a national basis, supported by established agreements, policies and 
procedures. Id.

D. Next Generation 911 Transition Order

    In July 2024, the Commission adopted the NG911 Transition Order, 
which established rules to create a consistent NG911 transition 
framework at the national level while also affording flexibility to 911 
Authorities to modify the transition framework at the state, regional, 
local, territorial, or Tribal level.\40\ The new transition rules 
specify a two-phased approach to guide the transition to NG911, in 
which 911 Authorities initiate each phase by submitting a valid request 
to OSPs within the relevant jurisdiction and OSPs must comply with 
NG911 requirements for that phase within a defined period. As part of 
the order, the Commission adopted a definition of ``Next Generation 
911'' that includes interoperability, security, use of commonly 
accepted standards, and other criteria as core elements of the 
definition.\41\ The Commission also noted the potential for NG911 to 
support improved reliability and interoperability and that some 
commenters had urged us to consider specific reliability and 
interoperability requirements.\42\ While the Commission deferred 
consideration of these issues in the Order, it recognized that they 
warranted further scrutiny.\43\

Transition Order also requires that emergency communications centers--

911 requests for emergency assistance.\44\ The Commission explained 
that this language incorporates an accessibility component into the 
NG911 definition, and agreed with Communications Equality Advocates 
(CEA) that NG911 must support accessible technologies.\45\ Several 
commenters urged the Commission to consider additional measures to 
enhance NG911 accessibility. While the Commission declined to address 
those proposals because they were outside the scope of that proceeding, 
it resolved to ``continue to monitor the development of NG911 systems 
and technologies'' and ``to take steps as necessary to ensure that 
NG911 is fully accessible to all.'' \46\

Discussion

A. The Need for Rules To Promote the Reliability and Interoperability 
of NG911 Networks

    NG911 architecture offers distinct advantages over legacy 911 
technologies, including the possibility of greater reliability, 
redundancy, interoperability, and accessibility.\47\ In order to 
realize these advantages, however, NG911 networks must be designed to 
ensure resiliency and avoid potential single points of failure. Unlike 
legacy 911 networks, in which 911 call routing and delivery by a CSP 
typically occurs within the same service area as the destination PSAP, 
NG911 networks frequently aggregate traffic from various OSPs and 
widespread regions and transport it to geographically distant network 
components for processing and eventual delivery to ESInets for routing 
to the appropriate PSAP. In addition, NG911 network providers often 
contract with third parties to operate servers and other critical 
facilities that support 911 call routing and other key functions in 
multiple states and jurisdictions.\48\ Without measures to ensure the 
resiliency of these critical components, failure of NG911 networks can 
lead to large, multistate outages. The introduction of NG911 and IP-
based technologies therefore requires collaboration between industry, 
public safety participants including 911 Authorities, and the 
Commission to ensure that technology-enabled optimization does not 
introduce unacceptable risks that imperil 911 reliability, resiliency, 
and accessibility.\49\

---------------------------------------------------------------------------

    Since the Commission adopted the 911 reliability rules for CSPs in 
2013, the nation has continued to experience periodic ``sunny day'' 
outages that have impaired the ability of millions of Americans to 
access 911. While many of these outages have been local, some have been 
large, multistate outages associated with IP-based networks.
    <bullet> In 2014, an outage in a service provider's 911 call-
routing facility in Colorado caused 11 million people to lose 911 
service for up to six hours, prevented emergency calls from reaching 81 
PSAPs across seven states,

[[Page 23773]]

and resulted in more than 6,600 calls to 911 never reaching a PSAP.
    <bullet> In 2018, a service provider experienced a nationwide 
outage on its fiber network that lasted for one and a half days, 
affecting 22 million customers across 39 states, including 
approximately 17 million customers across 29 states who lacked reliable 
access to 911.
    <bullet> In December 2022, an outage affected 911 calling for a 
service provider's VoIP customers in much of the South, and another 
service provider experienced two outages in 2022 disrupting 911 service 
to thousands in North Dakota and South Dakota for several hours.
    <bullet> In February 2024, a provider experienced a nationwide 
wireless service outage that lasted at least twelve hours and rendered 
all voice and 5G data services unavailable for all users. More than 92 
million voice calls were blocked, including more than 25,000 calls to 
PSAPs.
    <bullet> In April 2024, a service provider experienced an outage 
caused by a cut fiber optic cable adjacent to its central office in 
Kansas City, Missouri. The outage disabled a portion of the provider's 
high-capacity transport network for 911 and non-911 traffic originated 
by various OSPs in different states, including 911 traffic that had 
first been collected by a 911 aggregator--a service provider that 
segregates and consolidates 911 calls from OSPs and routes them to the 
appropriate PSAP or ESInet.
    Some of these recent 911 outages have exposed possible gaps in the 
coverage of the existing 911 reliability rules applicable to CSPs. The 
current rules relating to ``critical 911 circuits'' require CSPs to 
certify whether they have eliminated all single points of failure 
between the selective router, ALI/ANI databases, or equivalent NG911 
components, and the central office serving each PSAP. However, in some 
of the multistate outages noted above, the vulnerabilities contributing 
to the outage were found to exist at points in the 911 call flow 
downstream from the OSP (which is already required under Sec.  9.4, 
9.10, or 9.11 to transmit all 911 calls to PSAPs) but upstream from 
either the selective router in legacy 911 environments or the ESInet in 
transitional or NG911 environments. In many cases, those points are 
operated by third parties that transport 911 traffic over high-capacity 
fiber from OSP networks to the ESInets that directly serve PSAPs. In 
other cases, OSPs segregate their 911 traffic and hand it off to 911 
aggregation services, which deliver 911 traffic consolidated from 
multiple OSPs to PSAPs and ESInets. When these transport and 
aggregation components fail, they can interrupt 911 call flow to many 
PSAPs. Yet, because these components do not deliver calls directly to 
PSAPs at the local level, providers can argue that the components fall 
outside of the scope of the current reliability rules, particularly in 
the NG911 environment. We therefore believe Commission action is needed 
to address the reliability of these critical facilities in NG911 
ecosystems. We seek comment on this analysis.
    Another indicator of the need to revisit the 911 reliability rules 
for CSPs is that many of the multistate 911 outages reported to the 
Commission are ``sympathetic'' outages, i.e., outages reported by one 
entity that are caused by a failure in the network of another 
entity.\50\ Based on the data available in NORS, there have been at 
least 92 reported ``sympathetic,'' multistate outages in 2024 
alone.\51\ The Commission has noted that these ``sympathy reports 
contain information regarding service outages that, while caused by a 
failure in the network of another provider, nonetheless have an effect 
on the reporting service provider that may have public safety 
implications.'' \52\ The high frequency and widespread scope of these 
sympathetic outages highlights the degree to which carriers 
increasingly rely upon large third-party service providers to aggregate 
and transport their traffic. These sympathetic outages usually are 
outside the scope of the existing 911 reliability rules, because CSPs 
can claim such outages occur in network elements that do not directly 
serve PSAPs and because the 911 reliability rules do not apply to OSPs. 
As a result, sympathetic outages expose a potential gap between our 
outage reporting and reliability certification rules, and the 
Commission currently has a limited ability to correlate reliability 
certifications with multistate outages reported in NORS.

---------------------------------------------------------------------------

    When the Commission adopted the 911 reliability rules for CSPs, it 
committed itself to review the rules in the future ``to determine 
whether they are still technologically appropriate and both adequate 
and necessary to ensure reliability and resiliency of 911 networks.'' 
\53\ The Commission stated that it would consider ``how NG911 networks 
may differ from legacy 911 service as well as outage reporting trends, 
adoption of NG911 capabilities on a nationwide basis, and whether the 
certification approach has yielded the necessary level of compliance.'' 
\54\ Given the recurrence of major, multistate 911 outages, we believe 
the 2013 rules are not sufficient to safeguard 911 service in an NG911 
environment, and that there are several ways that the current rules 
could be improved. We seek comment on this analysis.
---------------------------------------------------------------------------

    \53\ 911 Reliability Order, 28 FCC Rcd at 17533, para. 159.
    \54\ Id.
---------------------------------------------------------------------------

    First, the rules could more clearly specify which types of 
providers of NG911 capabilities qualify as CSPs that must comply with 
the reliability best practices in Sec.  9.19 and file annual 
reliability certifications. The current rule refers to NG911 
capabilities and/or ``functional equivalents'' of specified legacy 
capabilities. Although we believe that the Commission made clear its 
intent that NG911 capabilities be considered equivalent if they 
contribute to the routing of 911 traffic or to the storage or retrieval 
of associated location information, the generalized nature of this 
definition may explain why NG911 service providers are underrepresented 
among providers filing annual reliability certifications; of the 290 
CSPs that filed 911 reliability certifications in 2024, only a small 
minority were NG911 providers. To the extent providers of NG911 
capabilities are uncertain about whether they fall within the 
definition of CSPs, they also may not be implementing the Commission's 
reliability best practices.
    The need for updating our rules regarding covered NG911 facilities 
is heightened by the fact that the entities operating the legacy 911 
facilities that are highlighted in the rules--i.e., selective routers 
and ALI/ANI databases--are retiring these facilities as they are 
superseded by NG911 networks.\55\ As a consequence, continuing to rely 
solely on the 2013 rules to cover the transition from legacy 911 to 
NG911 could lead to reduced transparency and a weakening of reliability 
safeguards. Updating the rules to ensure that the functional equivalent 
standard clearly encompasses NG911 technology therefore should provide 
additional certainty that NG911 service providers are covered by our 
rules and improve the reliability practices of NG911 networks and the 
accessibility of NG911

[[Page 23774]]

service. We seek comment on our view that updating the rules is needed 
to address these issues.
---------------------------------------------------------------------------

    \55\ NG911 Transition Order at *64, para. 186.
---------------------------------------------------------------------------

    The reliability rules also do not address interoperability between 
ESInets--understandably so given that few ESInets existed when the 
rules were adopted in 2013. It has become clear, however, that one of 
the greatest potential benefits of NG911 technology is its ability to 
empower PSAPs to use ESInets to seamlessly transfer 911 calls and 
associated call data to other PSAPs that are better positioned to 
respond and deploy resources for emergencies. This life-saving benefit 
is an emerging one, but its potential will be substantially diminished 
if PSAPs cannot transfer calls to nearby PSAPs located across a state 
border, or if someone must retranslate or reformat the traffic to allow 
transfers to occur. In order to ensure that this capability exists 
nationwide, we believe we should consider adopting interoperability 
standards to facilitate the interstate flow of information between 
ESInets. We seek comment on our view that interoperability requirements 
are needed.

B. 911 Reliability

1. Expanding the Scope and Applicability of the 911 Reliability Rules
    To account for the transition from legacy 911 to NG911, we propose 
to modify our definition of ``covered 911 service provider'' as 
follows. First, we would specify certain NG911 capabilities that 
satisfy the ``functional equivalent'' capability language of the 
current rule. Second, we propose to modify the current rule regarding 
what ``direct service'' to a PSAP or other answering point means, 
codifying language from prior Commission orders. Third, we propose to 
add five new NG911 CSP categories to cover both the expanding network 
gap between OSPs and state and local governments and the increasingly 
interstate and interlinked nature of NG911 ecosystem facilities. We 
seek comment on these proposals.
    When the Commission adopted the reliability rules in 2013, it 
focused their application on service providers that, collectively, 
carry out the primary function of the 911 network: routing emergency 
calls to the geographically appropriate PSAP based on the caller's 
location.\56\ The Commission recognized ``that overbroad rules could 
inadvertently impose obligations on entities that provide peripheral 
support for NG911 but may not play a central role in ensuring 911 
reliability[.]'' \57\ It therefore stated that it would only consider 
OSPs, internet service providers (ISPs), backhaul providers, 
aggregators, commercial data centers, and ESInets as CSPs to the extent 
they provide covered 911 capabilities directly to PSAPs.\58\ The 
Commission further interpreted ``direct'' service to a PSAP to require 
a contractual arrangement or tariff agreement with the PSAP.\59\

to its main network.

---------------------------------------------------------------------------

    The 911 facilities enumerated in the current definition of CSPs 
correspond to the rule's definition of ``critical 911 circuits,'' which 
comprise 911 facilities that originate at a selective router or its 
functional equivalent and terminate in the central office that serves 
the PSAP(s) to which the selective router or its functional equivalent 
delivers 911 calls, including all equipment in the serving central 
office necessary for the delivery of 911 calls to the PSAP(s).\60\ 
Critical 911 circuits also include ALI and ANI facilities that 
originate at the ALI or ANI database and terminate in the central 
office that serves the PSAP(s) to which the ALI or ANI databases 
deliver 911 caller information, including all equipment in the serving 
central office necessary for the delivery of such information to the 
PSAP(s).\61\

    When the Commission adopted the reliability rules in 2013, it 
declined to enumerate specific NG911 capabilities in the rules, because 
NG911 was still early in its development at that time, and the 
Commission expected that NG911 functionalities would evolve 
significantly in the future.\62\ Instead, the Commission stated that it 
would consider NG911 service providers to be CSPs if they provided 
capabilities ``functional[ly] equivalent'' to the legacy routing 
capabilities enumerated in the rules or if they were the last service-
provider facility connecting to a PSAP.\63\

---------------------------------------------------------------------------

    The Bureau issued a Public Notice in 2018 that revisited the 
definition of ``covered 911 service providers.'' \64\ Public safety and 
governmental commenters broadly agreed that the current definition of 
CSPs is too narrow, noting that it excludes the growing class of 
critical NG911 services that are provided by subcontractors and other 
parties that have no contractual relationship with PSAPs and therefore 
do not ``directly'' serve a PSAP under the current rules.\65\ APCO, for 
example, asked the Commission ``to include any entity that provides 9-
1-1, E9-1-1, or NG9-1-1 capabilities, directly or indirectly'' and 
reported that ``entities without a direct relationship to a PSAP have 
found methods to impact the ALI, routing, or supplemental data relevant 
to a 9-1-1 call.'' \66\ The Colorado Public Utility Commission (COPUC) 
stated that the definition of CSPs ``should encompass any service or 
network component that could potentially impact 9-1-1 call delivery to 
the PSAPs, even if that service or network component is not directly 
contracted to deliver 9-1-1 calls and location information to the 
[PSAP].'' Comments from service providers mostly opposed broadening the 
definition of CSP. For example, the Alliance for Telecommunications 
Industry Solutions (ATIS) stated its belief that the current rules 
``adequately encompass transitional and NG9-1-1 networks,'' and 
Motorola Solutions, Inc. (Motorola) requested that the definition be 
clarified by adding an express requirement that CSPs must have a direct 
contractual relationship with a PSAP.

---------------------------------------------------------------------------

    The NG911 Transition Order requires OSPs to provide SIP-based 911 
traffic to 911 Authorities (typically via ESInets) to enable those 
authorities to establish NG911 networks in their states. While 
establishing NG911 service brings inherent potential advantages to 
reliability and interoperability, the Commission did not seek to amend 
the 911 reliability or outage notification rules in that proceeding. 
Nevertheless, certain commenters suggested that the Commission update 
its rules to better address network reliability in an NG911 
environment, including to encompass emerging classes of NG911 service 
providers.\67\ We agree, and we

[[Page 23775]]

accordingly propose the measures described below.

---------------------------------------------------------------------------

    Specification of Certain NG911 ``Functional Equivalents.'' We 
propose to amend the definition of ``covered 911 service provider'' to 
specify that NGCS Routing Facilities and NGCS Location Facilities are 
examples of NG911 capabilities that are functionally equivalent to the 
legacy facilities enumerated in the rule (i.e., selective routers and 
ALI/ANI databases).\68\ We further propose to define these NG911 
capabilities consistently with the definitions adopted in the NG911 
Transition Order. Together, these amendments would provide greater 
specificity for providers of these equivalent NG911 capabilities that 
they qualify as CSPs and are subject to the reliability standards in 
Sec.  9.19 and the reporting requirements in Sec.  4.9. We seek comment 
on this proposal.
---------------------------------------------------------------------------

    \68\ See proposed rules at Sec. Sec.  9.19(a)(4)(i)(A), (B) and 
9.19(a)(15)-(16).
---------------------------------------------------------------------------

    We believe that these proposed amendments are consistent with the 
Commission's intent in adopting the current rule and would provide 
additional guidance as to the types of NG911 network functions and 
their associated network elements that are the ``functional 
equivalents'' of covered legacy routing facilities. The Commission 
explained in the 911 Reliability Order that the routing of a legacy 911 
call is accomplished via an aggregation point called a selective 
router, which identifies the PSAP that should receive the call based on 
the caller's phone number and address.\69\ The selective router then 
determines the correct routing path for the call and transmits the 
call, together with the caller's location and telephone number, to the 
central office serving the PSAP. Finally, the central office transmits 
the 911 call and associated caller information to the PSAP, typically 
along dedicated trunk lines. The PSAP validates the caller's location 
and callback number by querying ALI and ANI databases before 
dispatching emergency services. Wireless 911 calls are routed 
similarly, but the caller's location must be determined using other 
technologies and third-party providers.\70\ We set forth a simplified 
graphic representation of a legacy network below. Service providers 
operating the legacy facilities that perform essential routing and 
transmission capabilities--i.e., selective routers and ALI and ANI 
databases--are clearly defined as CSPs in the current rule.\71\

    In the NG911 Transition Order, the Commission recognized that 
``[t]he transition to NG911 involves fundamental changes in the 
technology . . . use[d] to receive and process 911 traffic, and it 
requires equally fundamental changes in the way OSPs deliver 911 
traffic to PSAPs.'' \72\ The default NG911 rules adopted in the NG911 
Transition Order require OSPs to deliver 911 traffic to an NG911 
Delivery Point that each 911 Authority may designate within its state 
or territory.\73\ From that demarcation hand-off point, 911 Authorities 
are responsible for transmitting 911 traffic to the PSAP(s), which may 
be accomplished through a combination of interconnected NGCS provided 
via the 911 Authority's ESInet(s).\74\ These services may include 
Location Validation Functions (LVFs), Geographic Information Systems 
(GISs), Emergency Services Routing Proxies (ESRPs), Emergency Call 
Routing Functions (ECRFs), and Policy Routing Functions (PRFs).\75\ The 
LVF is a server that validates civic location information against a GIS 
database to deliver more dynamic and actionable information about a 
caller's location than legacy ALI/ANI databases can.\76\ GIS is a 
mapping system that collects, stores, and analyzes spatial data, 
ensuring that emergency services can pinpoint where to send help.\77\ 
Next, an ESRP, which is a routing engine that determines the next hop 
for the 911 call, queries an ECRF, which is a database function that 
determines the appropriate destination PSAP by mapping the caller's 
validated location to maps with the boundaries of emergency response 
zones.\78\ The call then is routed to the geographically appropriate 
PSAP in accordance with the PRF, which is a ruleset that decides how 
the call should be routed based on predetermined policies (e.g., 
priority levels, time of day, and load balancing).\79\ We set forth a 
simplified graphic representation of a Phase 2 NG911 network below.\80\

    We believe the LVF and GIS core services are NG911 capabilities 
that are functionally equivalent to the ALI/ANI databases used in 
legacy networks. While they are not identical in a technical or 
engineering sense, we believe that these NGCS Location Facilities are 
equivalent in a functional sense because they similarly validate the 
911 caller's location by reference to databases of geographical and 
civic data using information about the caller that

[[Page 23777]]

has been provided by their OSP.\81\ In turn, we believe that the ESRP, 
ECRF, and PRF core services are NG911 capabilities that are 
functionally equivalent to legacy selective routers, because they 
similarly determine the path along which to route 911 traffic so that 
it reaches the appropriate PSAP.\82\ We refer to them collectively as 
NGCS Routing Facilities.
---------------------------------------------------------------------------

ANI databases will be replaced with IP-based systems with more

---------------------------------------------------------------------------

    As has always been the case with Sec.  9.19, this proposal, as well 
as those described below, are service provider agnostic. In other 
words, rather than designate certain entities as CSPs by virtue of 
regulatory status or industry category, we propose to continue to focus 
on the services provided and the facilities operated. We seek to 
preserve flexibility in a rapidly evolving technology market so that 
only entities that ultimately provide critical 911 functions in an 
NG911 environment are the ones subject to our rules. The goal is to 
ensure reliability, interoperability, and accessibility of critical 
NG911 facilities, not to predetermine market outcomes or to usurp or 
constrain state and local government decision-making.
    We seek comment on these proposals and our analysis. Does the 
current definition of CSPs sufficiently encapsulate NG911 service 
providers, or should the definition specify which NG911 capabilities 
are the ``functional equivalent'' of the covered legacy routing and 
transmission services? Are LVFs, GISs, ESRPs, ECRFs, and PRFs examples 
of such functionally equivalent capabilities? Are these capabilities 
usually performed by non-governmental entities (e.g., via contracts or 
agreements) or are there instances where they are performed directly by 
governmental entities? Are there other NG911 facilities or services 
that constitute functional equivalents? If so, what functions do they 
perform, and which legacy elements do they replace? Because CSPs may 
not uniformly fit the definition of ``telecommunications carriers,'' 
should we clarify that, similar to the requirement in Sec.  9.4 of the 
Commission's rules, CSPs are required to transmit all 911 calls they 
receive to PSAPs? If not, on what basis should we treat CSPs 
differently from telecommunications carriers? We also request estimates 
of any new costs that would be caused by expanding the CSP definition 
in this manner.
    As we propose to expand the classes of entities covered by our 
NG911 reliability rules to ensure that the rules capture entities that 
perform critical NG911 functions, we seek comment on whether we should 
conform Sec.  4.5(e) in our outage reporting rules to similarly reflect 
this change. While Sec.  4.5(e) already applies to NG911 outages, it 
does not specifically reference outages within the NG911 ecosystem 
facilities that we propose to define as critical (e.g., Major Transport 
Providers, ESInet interconnection facilities, NGCS facilities, 
etc.).\83\ Should these facilities be identified explicitly in the 
rule, and, if so, how? We also seek comment on whether we should amend 
the outage-reporting thresholds in Sec.  4.5(e) to reflect additional 
outage impacts that are specific to the types of NG911 ecosystem 
facilities that we address in our proposed 911 reliability rules. If 
so, what should those NG911-specific outage effects be? The current 
rule includes a threshold of 900,000 user-minutes of lost communication 
with PSAPs. Are user-minutes (as defined in Sec.  4.7(e)) the 
appropriate metric for outages that are specific to NG911 facilities? 
\84\ If not, what metric would be appropriate?
---------------------------------------------------------------------------

    \83\ We note that an outage that exhibits any of the effects of 
an outage described in Sec.  4.5(e) would qualify as an ``outage 
that potentially affects a 911 special facility,'' regardless of 
whether the underlying 911 service is legacy 911 or NG911. See 47 
CFR 4.5(e).
    \84\ ATIS argued in a prior proceeding that the outage threshold 
calculations set forth in Sec. Sec.  4.5(e) and 4.7(e) are 
unsuitable for NG911 networks and that NG911 outage thresholds 
should be determined based on census or population data. See ATIS 
Comments, PS Docket Nos. 15-80, 13-75, at 15-16 (filed Jul. 30, 
2021) (``Unlike legacy 911 systems, NG911 systems using the i3 
architecture do not have access to telephone number counts. Legacy 
systems match a caller's phone number with information in the [MSAG] 
to determine a caller's location. With NG911 systems, calls are 
validated and routed using [GIS] data rather than the MSAG. Without 
telephone number counts, [CSPs] cannot calculate the number of user 
minutes potentially affected by an outage under Section 4.7(e) and 
thus cannot determine whether an outage potentially affects a 911 
special facility under Section 4.5(e).'').
---------------------------------------------------------------------------

    Direct vs. Indirect Relationships with PSAPs. We propose to modify 
the requirement in the rules that providers of NG911 equivalent 
functionalities must ``directly'' serve a PSAP or other answering point 
in order to qualify as a CSP. The Commission included the ``direct 
service'' limitation in the original reliability rules to avoid 
imposing obligations on providers that ``may not play a central role in 
ensuring 911 reliability.'' \85\ The Commission also recognized, 
however, that the scope of the CSP definition might need to ``be 
revised or expanded to cover . . . additional entities that provide 
NG911 capabilities, or in light of our understanding about how NG911 
networks may differ from legacy 911 service.'' \86\

    \86\ Id. at 17533, para. 159.
---------------------------------------------------------------------------

    Modern NG911 networks have evolved to route 911 calls to PSAPs very 
differently from legacy architectures. In legacy networks, PSAPs 
typically contract with a single entity (such as an ILEC) to receive 
routing and location information services via a selective router and 
access to ALI and ANI databases, and they typically contract with the 
same entity to receive call delivery via trunk lines from the entity's 
nearest central office.\87\ In contrast, NG911 routing is performed by 
many dispersed functional elements that may be operated by a variety of 
service providers, including OSPs, ESInet providers, their contractors, 
and other parties.\88\ A PSAP or 911 Authority may not have contractual 
relationships with any or all of these entities.

---------------------------------------------------------------------------

    We believe it is important that indirect providers of essential 
NG911 services comply with reliability best practices. As noted above, 
there was strong support for doing so among public safety and 
government commenters that responded to the 2018 Reliability Public 
Notice. We are concerned, however, that including all indirect service 
providers within the definition of CSPs could unnecessarily increase 
the number of service providers that must file reliability 
certifications each year well beyond the increase we anticipate as a 
result of specifying certain NG911 capabilities that are ``functionally 
equivalent'' to covered legacy capabilities. That increase could drive 
up the operating costs of service providers--and, consequently, the 
costs for individual subscribers and 911 Authorities--and could 
interfere with the Commission's ability to closely review reliability 
certifications to identify and address problems.
    We think the solution that best accomplishes our objective--while 
avoiding unnecessarily-burdensome certification and outage notification 
requirements--is to retain the direct service requirement but amend 
Sec.  9.19 to state that CSPs directly serving PSAPs are responsible 
for ensuring the reliability of all of the NG911 capabilities they 
provide to the PSAP, whether through contractors of any tier, vendors, 
or via leased facilities. This proposal largely would be a codification 
of the longstanding principle that CSPs

[[Page 23778]]

must comply with Sec.  9.19 reliability practices for facilities they 
lease from other parties, while the lessors themselves do not become 
subject to Sec.  9.19 reporting requirements by making their facilities 
available to a CSP.\89\ We believe this codification would ensure that 
reliability measures apply to essential NG911 functions while avoiding 
unnecessary burdens on providers and unnecessary distractions to PSAPs 
and 911 Authorities.

[CSPs] could contract with facilities lessors, if necessary, to 
audit and tag leased circuits, but that the entity providing 911 
service under a direct contractual relationship with each PSAP would 
remain responsible for certifying compliance with those 
requirements. We reaffirm those principles here, but clarify that 
[CSPs] (i.e., the entities with direct contractual relationships 
with PSAPs) that rely on such contracts may implement and certify 
reasonable alternative measures as set forth above. We emphasize, 
however, that the contracting out of certain functions, or the 
determination of a PSAP to contract with more than one entity for 
various aspects of 911 service, does not absolve individual entities 
of their respective obligations for reliable 911 service.'') (citing

---------------------------------------------------------------------------

    We seek comment on this proposal. Should providers of NG911 routing 
and transmission services be explicitly included in the definition of 
CSPs if they do not serve PSAPs directly? As the transition to NG911 
has advanced, how typical is it for these types of services to be 
provided indirectly by entities with no contractual relationships with 
PSAPs? How are the relationships with these entities structured or 
memorialized? Would retaining the ``direct service'' requirement 
provide adequate oversight to the Commission and 911 Authorities? What 
advantages and disadvantages would this approach bring in contrast with 
simply requiring third-party, indirect providers to submit their own 
certifications? What would the cost impact be?
    We also invite feedback on whether the proposed rules could hamper 
the flexibility of 911 Authorities to manage the implementation of 
NG911 in their jurisdictions. Would the rules interfere with 911 
Authorities' procurement processes or unduly impact the cost of NG911 
services? Would any of our proposals, if adopted, result in any 
existing contracts or agreements needing to be terminated or 
renegotiated, and, if yes, would that impact 911 service or costs or 
delay the transition to NG911? Would governmental entities prefer to 
have more or sole discretion over minimum reliability requirements or 
practices in their jurisdictions? How would eliminating the direct 
service limitation impact NG911 transition costs, and could it 
inadvertently slow NG911 deployments or discourage new market entrants?
    We note that, during investigations of 911 outages, it is common 
for service providers to claim that they are contractually prohibited 
from sharing their contractors' confidential business information.\90\ 
In response to one such claim, BRETSA argued that ``[i]f providers are 
contractually restricted from cooperating to provide information as to 
callers unable to reach 9-1-1 during an outage, then the Commission and 
the states must adopt rules permitting and requiring all providers to 
cooperate in supplying such information to PSAPs.'' How should the 
Commission address confidentiality concerns of indirect service 
providers? What is the appropriate balance for protecting and 
safeguarding non-public information (e.g., proprietary business 
information) and creating and maintaining a reliable and resilient 911 
system? Should 911 Authorities be allowed access to reliability 
certifications, and associated information, relating to indirect 
providers in addition to the certifications, and associated 
information, of CSPs?
---------------------------------------------------------------------------

    \90\ See, e.g., 2014 Multistate 911 Outage Report at 21-22 
(``Intrado suggests that it is contractually precluded from 
providing the Commission or PSAPs with a clear understanding of what 
happened, adding that its business units are under contract to 
varying service providers and government agencies, and that `those 
contracts are strictly honored.' '' Intrado further asserted that 
``it would be improper for [it] to `cross the lines' established by 
its customers relative to information considered by them to be 
confidential in order for Intrado to `glue together' a more complete 
picture of an outage for other parties, including, as the case may 
be, PSAPs or the Commission[.]'').
---------------------------------------------------------------------------

    Encompassing Other Essential NG911 Services. In order to improve 
the reliability of essential NG911 ecosystem facilities, we propose to 
add to the definition of ``covered 911 service provider'' the following 
classes of service providers that have emerged as critical to NG911 
services: (1) operators of ``a Location Information Server (LIS) . . . 
or equivalent IP 911 location database;'' (2) operators of ``a Legacy 
Network Gateway (LNG) used for conversion of Time Division Multiplexing 
(TDM) 911 traffic to Session Initiation Protocol (SIP) . . .;'' (3) 
operators of Major Transport Facilities, which are ``[d]edicated SIP 
transport facilities meeting or exceeding Optical Carrier 3 (OC3) in 
capacity that collect and/or transmit IP 911 traffic, either segregated 
or mixed with non-911 traffic, originated from multiple OSPs and 
transported over interstate routes, for ultimate transport and delivery 
to an NG911 Delivery Point or ESInet''; (4) operators of IP Traffic 
Aggregation Facilities, which are ``[f]acilities that collect and 
segregate IP 911 traffic from non-911 traffic for multiple OSPs, or 
transport such traffic for ultimate delivery to an NG911 Delivery Point 
or ESInet;'' and (5) operators of ``interstate interconnecting 
facilities between ESInets.'' \91\ We seek comment on this proposal, as 
discussed in further detail below.
---------------------------------------------------------------------------

    \91\ See proposed rules at Sec. Sec.  9.19(a)(4)(i)(C) through 
(G), 9.19(a)(12) and (13).
---------------------------------------------------------------------------

a. Operators of LISs and LNGs
    The framework adopted in the NG911 Transition Order addresses 
technology changes that are occurring in NG911 networks over the entire 
course of the 911 call flow, from origination to delivery to PSAPs. The 
in-state or in-territory NG911 Delivery Point serves as the demarcation 
point that presumptively divides responsibility for processing and 
transmitting NG911 traffic between OSPs on the one hand and 911 
Authorities on the other.\92\ The NGCS Location Facilities and NGCS 
Routing Facilities we discuss above address NG911 core services that 
are being provided on the 911 Authority side of the demarcation point.
---------------------------------------------------------------------------

    \92\ NG911 Transition Order at *3, 26, paras. 6, 71. The NG911 
Transition Order does not place any affirmative requirements on 911 
Authorities. Instead, it invites 911 Authorities to adopt the 
Commission's NG911 framework, and, if they do, OSPs providing NG911 
service to the 911 Authorities are assigned a series of performance 
and cost obligations from origination to the demarcation point in 
the absence of an alternate agreement with the 911 Authority. See 
id. at *2-3, paras. 2-7.
---------------------------------------------------------------------------

    On the OSP side of the demarcation point, the NG911 Transition 
Order requires OSPs that receive a valid request for NG911 service to 
incorporate certain NG911 functional elements into their networks, 
because those elements are necessary in order for ESInets to be able to 
route and deliver NG911 traffic

[[Page 23779]]

and to provide their full array of core services. First, the NG911 
Transition Order requires OSPs to put into operation a LIS or its 
functional equivalent (or to acquire equivalent services from a third 
party) in order to verify their customers' location information.\93\ 
That location information is then embedded with the 911 call and 
delivered to an NG911 Delivery Point or ESInet and is used by the 
ESInet's NGCS Location Facilities and NGCS Routing Facilities to route 
and deliver 911 calls. Second, in some cases, OSPs may be using an LNG 
(or acquiring equivalent services), in order to translate TDM-
originated 911 traffic into SIP format before the 911 traffic is handed 
off to the ESInet.\94\
---------------------------------------------------------------------------

    \93\ Id. at *2, para. 3. See also 47 CFR 9.28 (formally defining 
a LIS as a ``functional element that provides locations of 
endpoints. A LIS can provide Location-by-Reference or Location-by-
Value, and, if the latter, in geodetic or civic forms. A LIS can be 
queried by an endpoint for its own location, or by another entity 
for the location of an endpoint.''). ``A LIS [may] be a database, or 
[may] be a protocol interworking function to an access network-
specific protocol. In NG9-1-1, the LIS supplies location (by value 
or reference) to the endpoint, or to a proxy operating on behalf of 
the endpoint.'' NENA i3 Standard, Sec.  4.10 (emphasis removed).
    \94\ NG911 Transition Order at *26, para. 71.
---------------------------------------------------------------------------

    Because all 911 traffic must access LISs and all TDM-based 911 
traffic must be converted to SIP format via LNGs, we believe it is 
critical that operators of these facilities employ reasonable 
reliability practices. The need for reliability is especially 
significant given that national carriers appear to be relying on a 
relatively small number of these facilities to service large portions 
of their networks and to deliver 911 traffic to ESInets across many 
states. We seek comment on our proposal to designate operators of LISs 
(or equivalent IP 911 location databases) and LNGs as CSPs.
b. Operators of Major Transport Facilities and IP Traffic Aggregation 
Facilities
    When the Commission adopted the reliability rules in 2013, it 
excluded third-party transport providers and 911 aggregation services 
from the definition of CSPs because, at that time, they did not play a 
central role in the provision of 911 service.\95\ We tentatively 
conclude that, in the decade that has since passed, these providers 
have become crucial to the provision of NG911 service at the interstate 
and national level, and, therefore, they should be subject to the same 
reliability and transparency requirements as other providers of covered 
services. We seek comment on this tentative conclusion.
---------------------------------------------------------------------------

    \95\ 911 Reliability Order, 28 FCC Rcd at 17490, para. 39; id., 
at n.90 (noting a commenter's argument that the reliability rules 
``should apply to backhaul providers and aggregators of 911 call 
traffic'').
---------------------------------------------------------------------------

    Our understanding is that many OSPs now rely on high-capacity, IP-
based fiber networks provided by third parties--which we refer to as 
Major Transport Facilities--to carry their 911 traffic to ESInets and 
PSAPs. These transport networks aggregate traffic (both 911 traffic and 
non-911 traffic) from multiple OSPs located in various states and carry 
it over long distances. The degree to which the 911 ecosystem has 
become dependent on these intermediate transport services is reflected 
in the outage investigations conducted by the Commission and by the 
outage reports submitted by OSPs through NORS. As we describe above, a 
number of multistate ``sunny day'' 911 outages have been caused by 
failures arising in or otherwise compromising Major Transport 
Facilities. Despite their outsized impact on 911 service, these 
networks currently fall within a gap in the Commission's rules; as 
providers of third-party transport service, they are neither CSPs nor 
OSPs, meaning they are not covered by the 911 reliability rules that 
are focused on routing and transmission services near the end of the 
911 call flow nor by the Part 4 outage reporting rules relating to call 
originators and CSPs.
    We wish to be cautious in how we define Major Transport Facilities 
so that Sec.  9.19 continues to be focused on only the most critical 
911 and NG911 elements and does not encompass smaller transport 
providers whose facilities do not pose a risk of widespread 911 
outages. Accordingly, we propose to limit the definition Major 
Transport Facilities to providers that operate dedicated SIP transport 
facilities meeting or exceeding OC3 capacity; that also collect or 
transmit 911 traffic originated by multiple OSPs; and that also carry 
911 traffic over interstate routes for ultimate delivery to an NG911 
Delivery Point or ESInet.\96\ We derive the proposed OC3 capacity from 
the outage reporting requirements in Sec.  4.9. That rule requires 
``outage reporting for communication disruptions impacting major 
transport facilities, specifically those with significant traffic-
carrying capacity[.]'' \97\

80 FR 34350 (June 16, 2015).
---------------------------------------------------------------------------

    Operators of IP Traffic Aggregation Facilities provide a niche 
service to OSPs: they segregate or collect segregated 911 traffic from 
OSPs and process and transmit the traffic towards the appropriate NG911 
Delivery Points or ESInets.\98\ We allowed the use of such services in 
the NG911 Transition Order because they ``enable multiple small 
carriers to bundle their data streams and share the cost of 
transporting the pooled data stream to a common destination, resulting 
in lower overall costs than if each OSP paid for separate transport.'' 
\99\ As with Major Transport Facilities, a large percentage of 911 
traffic now passes through IP Traffic Aggregation Facilities. For 
example, one of these providers claims that it has ``deployments of 
NG911 call aggregation service in states and counties across the 
country'' \100\ and that its 911 aggregation network serves 40% of the 
U.S. population. The provider claims to process more than 1.8 million 
911 calls per month and to deliver the calls to more than 5,000 PSAPs.

---------------------------------------------------------------------------

    We expect the roles of Major Transport Facilities and IP Traffic 
Aggregation Facilities to only increase as a result of the NG911 
Transition Order, because it requires OSPs to deliver the 911 traffic 
they originate to NG911 Delivery Points that 911 Authorities may 
designate at any location within their state or territorial 
borders.\101\ If these newly-designated traffic hand-off points are 
located outside of an OSPs' certificated service areas, OSPs may choose 
to procure the services of Major Transport Facilities and/or IP Traffic 
Aggregation Facilities rather than incur the high cost of building out 
their own networks.
---------------------------------------------------------------------------

    \101\ NG911 Transition Order at *55, para. 163.
---------------------------------------------------------------------------

    We tentatively conclude that Major Transport Facilities and IP 
Traffic Aggregation Facilities have become critical to the overall 
reliability of the 911 ecosystem and that their operators therefore 
should comply with reasonable reliability standards. We

[[Page 23780]]

seek comment on this tentative conclusion. Commenters in the NG911 
Transition proceeding observed the important roles that these third-
party entities have come to have.\102\ We also believe that federal-
level oversight of Major Transport Facilities and IP Traffic 
Aggregation Facilities is appropriate because they typically have 
multi-state or national footprints that exceed the scope of regulation 
or contractual terms imposed by any individual state or local 
government.
---------------------------------------------------------------------------

    \102\ See, e.g., USTelecom Comments, PS Docket No. 21-479, at 5 
(filed Aug. 9, 2023) (noting that NG911 systems will make it more

---------------------------------------------------------------------------

    We seek comment on the inclusion of these providers in the 
definition of CSPs. Have Major Transport Facilities and IP Traffic 
Aggregation Facilities become critical to the reliable and 
interoperable transmission of 911 traffic to PSAPs? How frequently have 
outages impacting 911 originated within these facilities, and what were 
the causes and consequences of the outages? Would one or both of these 
definitions capture instances where ESInet operators accept 911 traffic 
at an NG911 Delivery Point, send the traffic out of state for 
processing, and then back in-state to the ESInet for ultimate delivery 
to a PSAP? Do our proposed definitions appropriately describe these 
providers, or should they be defined more narrowly or broadly? For 
example, should we update the ``OC3 and equivalent'' standard for Major 
Transport Facilities to ``1 Gbps (or 10 Gbps) Ethernet and 
equivalent,'' to better reflect modern IP transport facilities in use 
today? \103\ Should we further limit the definition of Major Transport 
Facilities so that it refers only to facilities that carry a minimum 
volume of 911 traffic? If so, what is an appropriate minimum threshold? 
Should it be based on the number of 911 calls handled by the facility, 
on the number of OC3 minutes of 911 traffic, or some other metric? 
\104\ Also, what specific costs would these providers incur if they 
were included as CSPs, and what would be the benefits to the 
reliability of the NG911 network? Are there other classes of providers 
that should be included as well, and why? \105\

broader TDM to IP technology transition is outside of the scope of 
today's Further Notice.
---------------------------------------------------------------------------

c. Operators of ESInet Interconnection Facilities
    Finally, we propose to designate interstate interconnecting 
facilities between ESInets as critical 911 facilities. As we explain in 
greater detail below, while ESInets are providing greater PSAP-to-PSAP 
interoperability within their areas of deployment compared to legacy 
networks, there is a concerning lack of interoperability between 
different ESInet providers. Interstate interoperability is especially 
low for the types of data associated with the advanced features that 
NG911 is meant to deliver, such as GIS-based location information, SMS 
text, and Multimedia Emergency Services (MMES), that enhance the 
accessibility of emergency services to persons with disabilities.
    We do not propose requiring ESInets to adopt any particular 
technological solution to the interoperability problem, only that they 
take reasonable measures to provide reliable and interoperable 911 
service and confirm their interoperability with other ESInets by 
conducting conformance testing. We expect, however, that whatever 
solutions ESInets adopt to become interoperable will require the 
exchange of potentially large amounts of data and may also require 
external data connections and therefore will be critical to the 
resiliency of NG911 service.\106\ We therefore propose that these 
interconnection facilities should be treated as critical facilities 
that are subject to Sec.  9.19 reliability standards and certification 
requirements. We seek comment on this proposal and on our analysis 
above. We also seek comment on how designating providers of 
interconnecting facilities between ESInets as CSPs would affect the 
accessibility of advanced, multimedia NG911 services for persons with 
disabilities, as well as estimates of cost impacts.

2. Reliability Requirements
a. Reasonableness Standard
    We propose that any entity providing the foregoing critical NG911 
capabilities or facilities be subject to the current requirement in 
Sec.  9.19 to take ``reasonable measures'' to ensure reliability.\107\ 
We believe moving to IP-based architecture in NG911 inherently improves 
reliability by enabling greater redundancy and geodiversity.\108\ We 
further believe that it is reasonable for NG911 CSPs to ensure network 
reliability by adhering to prevailing industry standards.\109\ We 
therefore tentatively conclude that these prevailing industry standards 
are achievable for CSPs at acceptable additional cost.\110\ We further 
propose that CSPs may presumptively meet this

[[Page 23781]]

reasonableness requirement by adopting reliability practices in three 
broad areas: physical diversity, network monitoring, and operational 
integrity (which as proposed will subsume and replace backup 
power).\111\ We seek comment on these proposals.

    Importantly, our proposed approach would retain the current 
structure of the 911 reliability regulations, which imposes a 
reliability ``reasonableness'' standard on all CSPs, subject to 
equitable remediation orders by the Bureau for failure to demonstrate 
reasonableness of network practices.\112\ We propose to continue to 
allow CSPs to achieve presumptive reasonableness for specified CSP 
facilities by affirmatively implementing network practices described in 
the regulations.\113\ This structure is designed to enable the Bureau 
to investigate \114\ and validate network reliability based on filed 
certifications which show how well and how much of a CSP's network 
meets the Commission's standards. This process in turn enables the 
Commission to take preemptive actions to prevent outages before they 
occur. Bureau investigations can proceed by asking CSPs to provide 
information about the costs they would incur to upgrade their network 
reliability measures and assessing, from a cost-benefit standpoint, 
whether incurring such cost would be reasonable in light of the 
increased risk of critical 911 facility failure created by the CSPs' 
existing measures.

consensus or to appropriate alternative measures demonstrated to be 
reasonably sufficient to mitigate the risk of failure.''). See also

    While we propose to keep the reasonableness standard that the 
Commission adopted in 2013, we propose to identify new ``best

presumptively satisfy the reasonableness requirement. We also propose 
to modify the process by which CSPs report alternative reliability 
measures to enable the Bureau to better assess reasonableness of 
network practices. We seek comment on this proposed framework, in 
tandem with the proposed reliability benchmarks below.
b. Benchmarks for CSP Demonstration of Presumptive Reasonableness
    We propose to expand the range of required network reliability 
practices to ensure they better capture all relevant factors in the 
reliability of NG911 networks.\115\ The Commission based its original 
2013 rules ``on the Derecho Report and other prior experiences with 
natural disasters'' and therefore required reliability certifications 
only for circuit diversity, central-office backup power, and diverse 
network monitoring.\116\ However, the Commission observed that as 
technologies evolve, ``categories based on legacy 911 networks may not 
adequately reflect reasonable measures to provide reliable service, 
particularly in an NG911 environment.'' \117\

    We intend for today's proposed benchmarks for presumptive 
reasonability to capture the IP network engineering principles of 
reliability, resiliency, redundancy, physical diversity, and geographic 
diversity, which we believe most responsible NG911 network operators 
should be implementing. We wish to preserve the flexibility of PSAPs, 
911 Authorities, and state governments regarding how best to allocate 
resources to meet their reliability needs,\118\ while still adequately 
capturing the increasingly interstate and interlinked nature of NG911 
where national standards may aid 911 Authorities.\119\ Finally, our 
intent is that these NG911 reliability benchmarks would not apply to 
the origination of 911 traffic by OSPs, but would apply to service 
providers who aggregate 911 traffic or perform other critical NG911 
functions and services for multiple OSPs.\120\

    The purpose of these benchmark and certification proposals is to 
give the Commission reasonable oversight of CSP reliability practices 
while avoiding micromanagement of the network construction and design 
decisions of private entities. Accordingly, we do not propose to 
specify the details of reliable network practices down to the level of 
daily operational decisions and practices. Rather, we seek to 
articulate the kinds of measures that would demonstrate presumptive 
reliability when requesting certification. We seek comment on how best 
to improve 911 reliability and gather information that is reasonably 
actionable for efficient and

[[Page 23782]]

effective Commission and 911 Authority oversight, while also ensuring 
robust notice of ``reasonable'' reliability compliance expectations for 
CSPs. We also seek comment on whether adopting a reasonable reliability 
standard of ``five nines'' availability would be another valuable 
measure for determining compliance, or whether annual CSP facility 
availability time should be reported in addition to these 
benchmarks.\121\ How should ``five nines'' availability be calculated?

(i) Physical Diversity
    We propose specifying that the critical IP paths subject to the 
rules be subject to physical diversity requirements appropriate to 
NG911 and transitional networks.\123\ For legacy 911 circuits, the best 
practice benchmark of audits and tagging will remain the same. For 
NG911 facilities, we propose that ``physical diversity'' would mean 
that critical paths established by CSPs must be geographically 
diverse,\124\ load-balanced,\125\ and capable of automatic failover to 
the backup element (e.g., redundant routers or node connections and 
links) and automatic reroutes to redundant paths in the transport layer 
in the event of path failure.\126\ Redundant routers or node paths and 
links should be located in different geographic locations (i.e., in 
different physical facilities). We seek comment on this proposal.

Report that all network elements and transport facilities are 
deployed with redundancy'').

balanced' if call volume is dynamically distributed among all 
available databases or call processing facilities rather than 
concentrated in one location. Calls assigned to each database should 
be automatically rerouted to the other in the event of a fault with 
the primary route. Furthermore, if two or more PSAPs share the same 
911 service provider and rely on each other as a backup PSAP for 
rerouting of 911 calls, the 911 service provider should consider 
assigning each PSAP to a different primary routing database.'').
    \126\ Id. at 14227, para. 45.
---------------------------------------------------------------------------

    In general, ``physical diversity'' means that data between two 
points in a network can be transmitted over diverse routes that do not 
share any common physical segments, such as fiber-optic cables, 
conduits, or structures, so that a single failure at any point on one 
of those data paths, such as a power outage, equipment failure, or 
cable cut, would not cause both paths to fail and disrupt the 
transmission of data between those points. Importantly, we propose to 
add geographic diversity as a necessary part of this updated definition 
for IP paths, to ensure service providers can automatically re-route 
911 traffic to travel over a different path that is both physically 
diverse and geographically separated. We seek comment on the 
appropriateness of geographical diversity as part of the physical 
diversity requirement for IP-based networks.
    In 2013, the Commission included ``circuit auditing and tagging'' 
as an element of the 911 reliability rules, which requires CSPs to 
certify annually whether they have (1) audited the physical diversity 
of critical 911 circuits \127\ or equivalent data paths to any PSAP 
served, (2) tagged such circuits to reduce the probability of 
inadvertent loss of diversity between audits,\128\ and (3) eliminated 
all single points of failure in critical 911 circuits or equivalent 
data paths serving each PSAP.\129\ If a CSP has not implemented the 
third element (i.e., the elimination of all single points of failure), 
it must certify ``[w]hether it has taken alternative measures to 
mitigate the risk of critical 911 circuits that are not physically 
diverse or is taking steps to remediate any issues that it has 
identified with respect to 911 service to the PSAP.'' \130\ Respondents 
also may certify that the circuit auditing requirement is not 
applicable because they do not operate any critical 911 circuits.\131\
---------------------------------------------------------------------------

    \127\ Critical 911 circuits are defined as ``911 facilities that 
originate at a selective router or its functional equivalent and 
terminate in the central office that serves the PSAP(s) to which the 
selective router or its functional equivalent delivers 911 calls, 
including all equipment in the serving central office necessary for 
the delivery of 911 calls to the PSAP(s).'' They also include 
automatic location information (ALI) and automatic number 
information (ANI) connecting circuits that originate at the ALI or 
ANI database and terminate in the central office that serves the 
PSAP. See 47 CFR 9.19(a)(5).
    \128\ The rules define tagging as ``[a]n inventory management 
process whereby critical 911 circuits are labeled in circuit 
inventory databases to make it less likely that circuit 
rearrangements will compromise diversity.'' Covered 911 Service 
Providers may use any system they wish to tag circuits so long as it 
tracks whether those circuits are physically diverse and identifies 
changes that would compromise such diversity. See 47 CFR 
9.19(a)(11).
    \129\ See 47 CFR 9.19(c)(1)(i).
    \130\ 47 CFR 9.19(c)(1)(ii)(A).
    \131\ For example, small or rural local exchange carriers (LECs) 
may provide administrative lines to PSAPs but do not typically 
operate selective routers or control the facilities that connect 
selective routers to the central offices serving each PSAP. In such 
cases, they could respond that the circuit auditing element of the 
certification is not applicable.
---------------------------------------------------------------------------

    In 2013, the Commission required CSPs to certify to circuit 
diversity measures for paths between a selective router or its 
functional equivalent and the central office serving a PSAP. The 
Commission further identified routing and 911 traffic aggregation as 
distinct functions performed by the selective router.\132\ While this 
standard always applies to aggregated circuits when service is directly 
provided to a PSAP, under today's proposals if 911 traffic aggregation 
and routing are occurring at different points, both functions would 
trigger the requirement under our rules specify the examples that 
``functional equivalence'' includes IP traffic paths from NGCS facility 
capabilities (when provided directly to PSAPs), or from an aggregation 
point located in a different central office from the selective 
router.\133\ In 2014, the Commission introduced concepts such as 
dynamic routing, load balancing, automatic re-routing, and geographic 
facility diversity as reliability best practices for IP network paths 
and facilities.\134\ In

[[Page 23783]]

2015, the Commission observed that NG911 networks achieve reliability 
and resiliency with geographic diversity and dynamic routing instead of 
traditional TDM circuit auditing and tagging.\135\ Today we propose to 
add critical paths of major transport facilities and 911 aggregation 
network facilities as subject to our physical diversity rules 
regardless of whether the provider has direct service contracts with a 
PSAP or other answering point.\136\ Furthermore, we propose to codify 
additional physical diversity technical standards to encompass both 
legacy and NG911 facilities, to ensure that NG911 entities will no 
longer have to explain each year that they are using the IP 
``alternative'' to legacy TDM 911 reliability. We seek comment on our 
assessment.

---------------------------------------------------------------------------

    Finally, we seek comment on whether our proposed reliability 
measure for IP physical diversity is sufficiently inclusive, and on the 
likely compliance costs and lives-saved benefits from adopting this 
rule. We note that today's proposed rules are not meant to capture 
every single transit provider of general internet traffic, but rather 
dedicated transport providers that carry substantial 911 traffic.\137\ 
Does the explicit inclusion of major transport paths and 911 aggregator 
networks capture enough of the critical 911 bottleneck infrastructure 
to reasonably improve 911 reliability? Or does this proposal sweep too 
many OSP operators of IP traffic-aggregated paths into the CSP 
category, and if so, what metric could be used to better distinguish 
the most critical 911 transport and aggregation points and paths which 
should be covered in an NG911 environment? Should we also designate 
additional paths to and from the LIS as covered critical paths, or 
would that expand the CSP category too far to include the majority of 
OSPs? In the alternative, should LIS and LNG operators be at least 
required to ensure physically diverse ingress and egress points from 
their facilities? What would the additional costs be of such an 
expansion of this benchmark?

``the Commission should establish rules requiring the transport of 
911 traffic over dedicated SIP lines, and highlight that there are 
several options available to OSPs to comply with IP delivery rules 
with varying reliability . . . . We decline to establish the 
requested rules . . . . At this time, we provide flexibility to 911 
Authorities, in concert with their NG911 vendors, to determine the 
IP-based SIP format to request from OSPs.''); NG911 Transition Order 
at *47, para. 140, n.414 (commenters ask the Commission to consider 
the costs of routing 911 traffic over a ``dedicated connection'' as 
opposed to ``best efforts public internet connections'') (internal 
citations omitted).
---------------------------------------------------------------------------

(ii) Network Monitoring
    In the 911 reliability rules adopted in 2013, the Commission 
required CSPs to certify whether they have taken the following steps to 
ensure reliable monitoring of critical components of their networks: 
(a) conducting audits of aggregation points for gathering network 
monitoring data, (b) conducting audits of monitoring links, and (c) 
implementing physically diverse aggregation points and links.\138\ We 
propose to expand this existing requirement--which requires physical 
diversity between monitoring points and physically diverse links to 
network operations center (NOC) control points--by also including 
appropriate NG911 monitoring technologies identified in prior 
Commission orders as methods of compliance.\139\
---------------------------------------------------------------------------

    \138\ See 47 CFR 9.19(c)(3)(i).
    \139\ CSRIC VI, WG 1 Report at 52 (``The NG9-1-1 SSP will be 
responsible for monitoring IP connections for transport alarms. 
Where appropriate, heartbeats may be used to verify the availability 
of network facilities. NG9-1-1SSPs should provide the means for 
capturing network traffic, generating alarms, and producing other 
metrics for monitoring and troubleshooting outages within NG 
Emergency Services Networks, as well as those impacting the ability 
of an NG Emergency Services Network to deliver calls to the target 
PSAP.'')
---------------------------------------------------------------------------

    We believe this revised rule should apply equally to both legacy 
and NG911 architectures. NG911-appropriate standards for network 
monitoring rely on automatic disruption detection and alarms.\140\ The 
legacy 911 best practice of network monitoring via link and aggregation 
point audits \141\ would continue to be a means of compliance for 
legacy facilities. In either case, network monitoring should ensure the 
performance of the critical NG911 ecosystem facilities of routers, 
LISs, and LNGs in real time by detecting failures, disruptions, or 
degradations in 911 service. We also propose that this new monitoring 
benchmark for IP networks should specify IP-appropriate monitoring of 
critical NG911 ecosystem facilities we identify today, including LNGs, 
LISs, and the IP routers responsible for path diversity. Should the IP 
monitoring benchmark be expanded further to interoperability 
capabilities, where applicable? We seek comment on our assessments and 
on this proposed benchmark.

---------------------------------------------------------------------------

(iii) Operational Integrity
    The current ``backup power'' portion of the 911 reliability 
certification requires CSPs to indicate whether they provide at least 
24 hours of backup power at any central office that directly serves a 
PSAP or at least 72 hours at any central office that hosts a selective 
router, and whether they have implemented certain design and testing 
procedures for backup power equipment.\142\ We propose to retain this 
requirement for legacy central office facilities. However, we believe a 
modified requirement should be applied to NG911 networks to ensure 
continued operation in the event of a power outage.
---------------------------------------------------------------------------

    \142\ See 47 CFR 9.19(c)(2)(i).
---------------------------------------------------------------------------

    IP-based NG911 facilities, especially when cloud-based, can 
reasonably be expected to have redundant and geographically distributed 
backups located in different facilities sufficient to ensure that a 
failure of any localized facility will not interrupt 911 traffic,\143\ 
and should have appropriate continuous power, such as an 
uninterruptible power supply (UPS) device.\144\ In 2014 the Commission 
observed that network architectures using ``two active databases in 
different geographic locations, each of which is capable of handling 
all 911 call traffic in the event of a fault in the other database, 
will be more reliable and resilient than those that route all calls 
through a single active database with backup equipment on passive 
``standby'' mode.'' \145\ We seek comment on whether to codify this 
geographic diversity standard as a best practice benchmark to improve 
reliability. We also seek comment on whether requiring geographic 
diversity

[[Page 23784]]

at different physical facilities is robust enough to ensure reasonable 
reliability. Should we go further and require geographic diversity to 
mean redundant functionality housed in different cities or states, not 
just in different physical locations? Given the increasing size of 
natural disasters, what would be an appropriate distance requirement? 
Should we further expand the same IP operational integrity benchmark to 
monitoring interoperability facilities, diverse IP paths, and redundant 
routers, as well as to LIS and LNG facilities?

C. Interoperability

    As noted above, the lack of interoperability is a known concern in 
NG911, which impairs and increases the cost of call and data transfer. 
CSRIC VII observed that the ``transition from legacy to IP-based 
networks, may result in hybrid system settings that commingle legacy 
and IP network elements. While in this hybrid state, the 911 systems 
operate at higher risk. For example, these systems may encounter 
challenges in ensuring interoperability with respect to 911 calls and 
related data.'' \146\ CSRIC VII also observed that data collected by 
NASNA from showed low levels of interstate interoperability, 
particularly for data associated with NG911 such as location or SMS 
text as well as for features that enhance accessibility, (e.g., 
Multimedia Emergency Services (MMES).\147\ CSRIC VII found that ``[t]he 
more advanced technologies used day to day by the general public such 
as multi-media services had a very low level of respondents indicating 
interoperability.'' \148\ As the NG911 transition progresses, these 
interoperability issues are likely to manifest into incompatibilities 
detrimental to the processing and receipt of 911 traffic and related 
information by 911 Authorities across state lines.\149\

2025), <a href="https://urgentcomm.com/911/how-is-ng911-progressing-">https://urgentcomm.com/911/how-is-ng911-progressing-</a> (``While 
the [NG911 i3] standards were written with interoperability in mind, 
if Vendor A interprets them differently than Vendor B, interfacing 
the systems doesn't go well and sometimes is nearly impossible.'').
---------------------------------------------------------------------------

    To address these concerns, we propose to adopt interstate 
interoperability requirements to support the reliable exchange of 
interstate 911 traffic between ESInets. Specifically, we propose to 
require that CSPs certify whether their interstate interconnecting 
ESInet facilities achieve interoperability for exchanged 911 traffic 
sufficiently to enable complete interstate transfers between 
ESInets.\150\ In that connection, CSPs would annually certify whether 
their interstate interconnecting ESInet facilities use conformance-
tested equipment and whether they have tested their interstate 
interoperability capabilities. If a CSP cannot certify to these 
elements, we propose to require the CSP to certify with respect to 
those facilities: (1) whether it (or its ESInet facility operator) has 
taken alternative measures to ensure interoperability between ESInets 
in multiple states and between providers; (2) whether it believes that 
one or more of the requirements of this paragraph are not applicable to 
its facilities; and (3) to additional questions about the non-
conforming facilities as directed by the Bureau. We also propose to 
apply the definition of ``NG911'' adopted in the NG911 Transition Order 
to CSPs. Finally, we seek comment on the scope of our proposed 
interoperability requirements relative to other NG911 elements and 
whether to define interoperability to cover those elements.
---------------------------------------------------------------------------

    \150\ Under our proposal, ESInet interconnecting facilities 
operator refers to an entity that provides communication 
capabilities between ESInets.
---------------------------------------------------------------------------

1. Interstate Interoperability, Conformance and Interoperability 
Testing, and Interoperability Certification
    Conformance and Interoperability Testing. We propose to adopt an 
interoperability best practice benchmark of testing and verification to 
support interstate interoperability. We recognize that there have been 
voluntary efforts to promote interoperability across NG911 vendors 
through best practices, standards development and conformance testing, 
but no national rules are in place for providers of NG911 capabilities. 
Conformance testing, a process generally planned and developed by 
industry organizations and conducted by certified labs, is a mechanism 
that could be used to ensure that devices and network equipment that 
are deployed are compliant with commonly accepted standards.
    Consistent with our existing framework for reliability 
certifications, we propose that CSPs submit an annual certification of 
whether the equipment in their networks has undergone conformance 
testing and if not, whether they are using alternative measures to 
ensure interstate interoperability. Under our proposed approach, CSPs 
would be required to certify that they are able to process and share 
interstate 911 requests for emergency assistance and all associated 
information consistent with commonly accepted standards. We seek 
comment on this proposal. Is a certification approach sufficient to 
ensure that interoperability between ESInets across multiple states can 
be achieved without the need for proprietary interfaces, and regardless 
of jurisdiction, equipment, device, software, service provider, or 
other relevant factors? Should we require CSPs to certify that they are 
capable of maintaining interstate interoperability during a ``sunny 
day'' outage or disaster scenario?
    We also seek comment on whether to adopt additional 
interoperability benchmarks, such as requirement to conduct 
interoperability testing between ESInets in addition to conformance 
testing of technology used by ESInets. Interoperability testing is an 
important mechanism for ensuring that CSPs are technically capable of 
supporting interoperability between states and different service 
providers. Unlike conformance testing, which can be used by a service 
provider to demonstrate its NG911 solution conforms to a standard and 
increases the likelihood of interoperability, interoperability testing 
involves two or more service providers to demonstrate the exchange of 
information. We therefore seek comment on adopting a benchmark that CSP 
perform interoperability testing with two or more ESInets in different 
states. To this end, we seek comment on requiring that CSPs annually 
test and certify that they have performed interoperability testing with 
at least two different providers in two different states, or if they 
are using alternative measures to satisfy interstate interoperability.
    Interoperability Certification and Alternative Measures. We propose 
that CSPs submit an annual certification attesting to both conformance 
testing and interoperability testing starting one year after OMB 
approval of any associated information collection requirements. We seek 
comment on whether CSPs will be reasonably able to conduct the required 
testing within this time period. What processes or standards for test 
labs need to be in place before conformance testing can begin? Are 
there any other barriers to either conformance testing or 
interoperability testing that would impact being able to submit this 
certification?
    Our proposed annual certification approach is consistent with our 
existing requirement under Sec.  9.19(c).\151\ We also propose to 
require CSPs to update their certifications annually to reflect any

[[Page 23785]]

changes in their interoperability solutions that render prior 
certifications outdated. In addition, we seek comment on whether there 
are other methods, in addition to conformance testing and 
interoperability testing, for verifying that CSPs comply with 
``commonly accepted standards'' and allow them to demonstrate that they 
are technically capable of providing interoperability. For example, is 
it necessary to specify end-to-end testing (typically required by the 
customer) and/or performance testing (testing that simulates a real 
world scenario)? \152\ Are any such methods more reliable than 
conformance and interoperability testing for verifying interstate 
interoperability? What are the potential costs of, and challenges with, 
implementing any such methods?
---------------------------------------------------------------------------

    \151\ 47 CFR 9.19(c).
    \152\ See, e.g., iCERT Interoperability Testing Report at 10; 
Brian Rosen Comments, PS Docket 21-479, at 4 (filed Jul. 28, 2023) 
(``Call transfer across ESInets is now standardized in NENA STA-
010.3, which is the standard that all current NGCS implementations 
are currently at or are expected to be upgraded to soon. Vendor 
testing at NENA ICE events and bilateral testing between vendors are 
proving interoperability today.'').
---------------------------------------------------------------------------

    Finally, we propose to adopt an alternative ``reasonable'' 
interoperability requirement for providers of interstate ESInet 
interconnecting facilities, following the same framework of Sec.  9.19 
for reliability. As with the current Sec.  9.19 reliability 
certifications, CSPs would be allowed to either certify to meeting the 
interoperability benchmarks specified in the rules or to certify that 
they have achieved reasonable interoperability using alternative 
measures. We seek comment on this proposal. What alternative measures 
in lieu of our benchmarks would likely be used to certify and 
demonstrate ``reasonable'' interoperability? Should we require that 
CSPs successfully test the transfer of interstate calls between ESInets 
in order to demonstrate ``reasonable'' interoperability? What other 
alternative measures would demonstrate reasonable interoperability?
    NG911 and Commonly Accepted Standards. We propose to amend Sec.  
9.19 of the rules to define providers of ``NG911'' capabilities by 
cross-referencing the definition of NG911 in Sec.  9.28 of the rules. 
The definition adopted in the NG911 Transition Order helps define 
common sets of features and parameters at various points in the 911 
call flow to allow any 911 call or text to be able to reach 911 call 
takers. We believe our proposal, consistent with the NG911 Transition 
Order, will help lay foundational elements to realizing 
interoperability between OSPs to 911 Authorities in multiple states. 
Under this proposal, CSPs would ``ensure interoperability'' and comply 
with ``commonly accepted standards'' similar to OSPs. Our proposed rule 
amendment would therefore ensure CSPs operate from the same baseline 
requirements to facilitate interstate interoperability and promote 
cooperation with OSPs. We seek comment on our proposal, including 
potential costs.
    In addition, we seek comment on alternative approaches to ensure 
interstate interoperability. In response to the NG911 NPRM, some 
commenters urged us to clarify the roles of OSPs and providers of NG911 
services.\153\ APCO proposed that in addition to focusing on the 
delivery of 911 traffic by OSPs, the Commission should take the ``next 
step toward achieving public safety's vision for NG9-1-1'' by 
initiating a further notice of proposed rulemaking to address 
``interoperability requirements for 9-1-1 service providers and other 
elements of the emergency communications chain.'' \154\ In that 
connection, we seek comment from 911 Authorities and others as to 
whether we should expand the scope of our proposed interoperability 
requirement, and, if so, to what other elements of the emergency 
communications chain? Similarly, we seek comment on whether to amend 
Sec.  9.19(a) of the rules to add a definition for ``interoperability'' 
for purposes of clarifying the obligations of NG911 service providers, 
including the definition of interoperability from the Spectrum Auction 
Reauthorization Act of 2023 (H.R. 3565), or some variation, for 
purposes of defining the scope of our interoperability requirements; 
and the potential benefits and costs of adopting such a definition.

    \153\ See, e.g., APCO Comments, PS Docket 21-479, at 4-5 (filed 
Aug. 9, 2023) (``The greatest impact the Commission can have on 
facilitating the transition to NG9-1-1 would be to require 
interoperability between OSPs and 9-1-1 service providers, and among 
9-1-1 service providers.''); Jack Varnado, Livingston Parish Sheriff 
Comments, PS Docket 21-479, at 1 (filed Aug. 9, 2023) (urging the

all forms of 9-1-1 traffic with ECCs in different states and/or 
served by different 9-1-1 service providers. Each 9-1-1 service 
provider could demonstrate compliance with this interoperability 
requirement by certifying that the ECCs it serves are able to 
exchange 9-1-1 traffic with at least three ECCs located in different 
states and/or served by other 9-1-1 service providers. Such a 
certification should include an attestation that the 9-1-1 service 
provider has confirmed interoperability through real-world testing 
at its sole cost.'' APCO Ex Parte, PS Docket 21-479, at 3 (filed 
Nov. 1, 2024).
---------------------------------------------------------------------------

    Intrastate Interoperability. Today's proposals cover interstate 
interoperability between ESInets. With respect to intrastate 
interoperability, we believe that 911 Authorities can address NG911 
interoperability within their jurisdictions pursuant to contracts and 
tariffs with providers of NG911 services and have the ability to order 
necessary testing and resolve interoperability disputes, including with 
sub-contractors, pursuant to such instruments. In addition, 911 
Authorities are in the best position to address intrastate 
interoperability from the border control function at the in-state or 
in-territory NG911 Delivery Point through ingress to ESInet connected 
PSAPs and between PSAPs. We seek comment on our view.

2. Interstate Interoperability for Text and Video Accessibility

    We seek comment on whether interoperability certifications relating 
to ESInet interconnection facilities should include specific 
certifications regarding interoperability of 911 text messaging and 
video accessibility consistent with the benchmarks discussed above. We 
believe that ensuring interoperability for non-voice NG911 
communications is equal in importance to ensuring interoperability for 
voice NG911 calls. In the NG911 Transition Order, the Commission 
extended NG911 requirements to OSPs providing non-voice 911 services, 
including covered text providers and internet-based Telecommunications 
Relay Service (TRS) providers. NG911 is specifically intended to 
provide improved support for the full range of 911 voice, text, data, 
and video communications, including promoting and enabling 911 access 
for individuals with disabilities.\155\ In its end state, NG911 will 
facilitate interoperability and system resilience, improve connections 
between 911 call centers, and support the transmission of text, photos, 
videos, and data to PSAPs

[[Page 23786]]

by individuals seeking emergency assistance.\156\

---------------------------------------------------------------------------

    We seek comment on how best to ensure that NG911 systems support 
interoperability for non-voice 911 services, with specific emphasis on 
text, video, and multimedia capabilities that support 911 access for 
people with disabilities. As noted above, NASNA's 2020 Interoperability 
Matrix reflected higher levels of interstate interoperability for 911 
voice calls but no or low levels of interstate interoperability for all 
other services, including text-to-911 and MMES. We ask commenters to 
provide updated information on interstate 911 interoperability by type 
of service, with particular emphasis on services used by those with 
accessibility needs. For example, what are the current levels of 
interstate interoperability for the following types of service: (1) 911 
voice calls; (2) location data; (3) text-to-911, including real-time 
text (RTT); and (4) MMES?
    Text Messaging. Regarding text messaging, in response to the NG911 
NPRM, Google and NENA proposed that we consider the implementation of 
new interoperable messaging protocols, such as Rich Communications 
Service (RCS).\157\ We seek comment on Google's view that, ``[b]y 
addressing interoperable text messaging as part of its NG911 efforts, 
the Commission can further enable members of the public to connect to 
lifesaving resources, family members, and friends in a more effective 
and secure manner.'' Do commenters agree with NENA and Google's 
concerns about text interoperability and comments about RCS, and if so, 
would RCS fall under our definition of ``commonly accepted standards''? 
We seek comment more generally as to whether the public interest is 
better served by the Commission making such determinations in the short 
term or allowing the marketplace to make such determinations over a 
longer period of time. We also seek comment on whether there are 
interoperability problems in the commercial wireless market that are 
impeding end state end-to-end NG911? We invite commenters to comment on 
the specific connectivity, data transmission, and security issues 
Google describes as inherent in SMS/MMS. What options are currently 
available to address the aforementioned concerns as part of our 
certification requirements for CSPs, including intrastate 
interoperability requirements, and issues and what options do 
commenters foresee becoming available in the near-term and long-term?

communications technology for 911 purposes. See FCC, Real-Time Text,

    Video. Point-to-point video calls can be instrumental to 
demonstrate the emergency at hand in order to expedite the provision of 
appropriate emergency assistance. Additionally, people with 
disabilities may benefit from video calling in order to communicate 
more clearly in conjunction with other modalities such as text 
communications. We seek comment concerning accessibility with 
particular focus on measures we can take to promote interstate 
interoperability between ESInets.\158\ In response to the NG911 NPRM, 
commenter Brian Rosen suggested that the Commission could adopt 
requirements to ensure ESInets support three-way video for Video Relay 
Service (VRS) within a reasonable period of time, such as 12 months. 
Further, three-way video has the potential to support individuals with 
speech disabilities relying on speech-to-speech relay services.\159\ 
Rosen claims that many vendors of NGCS systems plan to support video in 
upcoming releases and suggests imposing a regulatory deadline to do so. 
In addition, Communication Service for the Deaf, Inc. states that video 
sign-language communications in NG911 systems could occur in different 
ways, including through standard VRS, three-way video relay 
services,\160\ or direct video calling (DVC). DVC would allow a caller 
who uses sign language to place a call to a call taker who is both 
fluent in sign language and trained in handling emergency calls, 
potentially eliminating the need for a third-party intermediary.\161\ 
Should we amend our rules to require that NGCS systems support three-
way video for relay services, and support DVC? If so, within what time 
frame should such support be required for either service? What 
conditions or qualifications, if any, should be included in 
requirements associated with these video calls? We seek updated data on 
interstate interoperability needed to meet the needs of the 
accessibility community, including the feasibility of providing DVC or 
three-way video 911 calls that include VRS, and challenges with 
implementation during the transition to NG911 and relevant 
timelines.\162\
---------------------------------------------------------------------------

    \158\ NG911 Transition Order at *17, para. 43. In the NG911 
Transition Order, the Commission adopted an NG911 definition that 
includes accessibility as an essential requirement, consistent with 
the definition in the Spectrum Auction Reauthorization Act of 2023 
(H.R. 3565), which requires that NG911 ``be capable of processing 
`all types' of requests.'' The Commission agreed that this 
requirement mandates that NG911 standards support accessible 
technologies. NG911 Transition Order at **14, 61, paras. 34, 179. 
The Commission declined, however, to expand the scope of the 
proceeding to consider accessibility issues raised in comments, but 
consistent with its authority under the CVAA, committed to monitor 
the development of NG911 systems and technologies and be prepared to 
take necessary steps to ensure that NG911 is fully accessible to 
all.

traditional VRS uses a communications assistant fluent in sign 
language to enable a 911 caller to communicate through an 
intermediary, so that the VRS interpreter voices what the caller 
signs and signs back the call taker's response, while three-way 
video would allow the VRS caller, the 911 call taker, and the video 
interpreter to all be visible to each other on the same video call).

and a sign language interpreter).
---------------------------------------------------------------------------

    We further seek comment on any potential efficiencies that three-
way video and DVC, respectively, would achieve for PSAPs in NG911 
systems. Could three-way video improve accuracy and efficiency for 911 
call handlers to take an emergency call and dispatch the right 
assistance? Could DVC improve accuracy and efficiency in the handling 
of emergency calls? Could emergency calling-trained DVC call handlers 
located at regional or nationwide PSAPs send electronic dispatchable 
reports directly to the local PSAP, eliminating the need for 
intermediary interpretation? To what extent would three-way video and 
DVC services need to rely on each other's facilities and capabilities? 
\163\ What role

[[Page 23787]]

should Emergency Call Relay Centers play in processing DVC calls? Would 
it be possible to route these calls to a call taker at an Emergency 
Call Relay Center (ECRC), who would then transmit the caller's 
information to a dispatcher at the appropriate PSAP? Should the 
Commission require all VRS providers to direct all incoming 911 calls 
to an ECRC upon receipt, to facilitate such direct communication? What 
are the costs and benefits associated with each of these services? What 
modifications to the NG911 architecture would be needed to enable DVC 
calls? What modifications would be needed to enable three-way video?

caller's appropriate PSAP . . . If the ability to use DVC is 
integrated into the NG911 infrastructure, could 911 calls placed by 
ASL-fluent callers be placed directly to an ASL-fluent 911 call 
taker without being routed through a VRS provider?'').
---------------------------------------------------------------------------

    We also seek comment regarding current IP-based relay \164\ 
provider capabilities and how to expand them. Do commenters agree that 
IP-based relay services providers currently supply a VoIP audio 
connection through a VPC, and that, to support video 911 calls, these 
providers would have to provide a video and audio connection, which 
current VPCs cannot handle? To enable IP-based relay services providers 
to support such calls, should we amend our rules to require ESInets to 
support internet connections, including video, via VPNs, to the 
ESInets, and if so, within what time frame, and subject to what 
conditions or qualifications? In that connection, do commenters agree 
with Brian Rosen that, to support three-way 911 video calls, IP-based 
relay providers would need to use the NGCS bridge, because bridges are 
used extensively in NG911 system to support attended transfer (so the 
call taker(s) can hear/see the call while they are completing the 
transfer--911 calls are not placed on hold)? If so, would this 
represent a change to their current process, which uses a Provider 
bridge, at least when supporting Voice carryover/hearing carryover? 
What are the costs associated with requiring three-way video support at 
the ESInet, and would such a requirement ensure equivalence for callers 
who are deaf or hard of hearing or have a speech disability?
---------------------------------------------------------------------------

    \164\ This would include VRS, IP Relay Services, and certain 
forms of IP Captioned Telephone Services.
---------------------------------------------------------------------------

D. Implementation and Oversight

    In order to assist in monitoring compliance with our proposed rules 
for NG911 reliability and interoperability, we propose to update our 
911 reliability data collections and oversight mechanisms. In the 911 
Reliability Order, the Commission stated that ``if a Covered 911 
Service Provider certifies that it has taken alternative measures to 
mitigate the risk of failure, or that a certification element is not 
applicable to its network, its certification is subject to a more 
detailed Bureau review.'' \165\ If the Bureau's review indicates that a 
provider's alternative measures are not reasonably sufficient to ensure 
reliable 911 service, the Commission stated that the Bureau should 
first engage with the provider and other interested stakeholders (e.g., 
affected PSAPs) to address any shortcomings. To the extent that such a 
collaborative process does not yield satisfactory results, the 
Commission stated that the Bureau may order remedial action consistent 
with its delegated authority.\166\ The Commission intended this process 
to allow flexibility to employ alternative--but reliable--network 
designs and technologies, not to create an exception that would swallow 
the rule.\167\
---------------------------------------------------------------------------

    \165\ See 47 CFR 0.392(j); 911 Reliability Order, 28 FCC Rcd at 
17497 para. 62 (``The Bureau will consider a number of factors in 
determining whether the particular alternative measures are 
reasonably sufficient to ensure reliable 911 service. Such factors 
may include the technical characteristics of those measures, the 
location and geography of the service area, the level of service 
ordered by the PSAP, and state and local laws (such as zoning and 
noise ordinances).'').
    \166\ See 911 Reliability Order, 28 FCC Rcd at 17497 para. 63.
    \167\ 2015 Reliability Recon. Order, 30 FCC Rcd at 8654-55, 
paras. 2, 10-11.
---------------------------------------------------------------------------

    As discussed below, we believe that revised reporting requirements 
would be helpful to Commission staff and 911 Authorities in identifying 
risks to the reliability and interoperability of 911 traffic, including 
single points of failure, and ask commenters to identify specific 
information that providers should include in their certifications. We 
also seek comment on measures the Commission could take to limit the 
burden of reporting on NG911 reliability and interoperability. We also 
seek comment on how to better identify single points of failure that 
could have cascading effects on 911 traffic in multiple states. To what 
extent could the Commission limit the burden of any reporting 
requirements by providing increased flexibility for providers or 
businesses identified as small by the Small Business Administration? 
\168\ We also propose to require disclosure of reliability and 
interoperability certifications to 911 Authorities. In that connection, 
we seek comment on establishing procedures for 911 Authorities to 
report concerns to the Bureau to conserve limited resources and focus 
attention on critical elements that could result in multistate outages 
or hamper interstate interoperability. We tentatively conclude that 
improving 911 Authorities' access to information about the 911 
reliability measures in place within their states would amplify the 
Commission's ability to address potential risks to NG911 service and 
enable 911 Authorities to assess taking their own measures to prevent 
and mitigate disruptions to 911 service in their jurisdictions. We seek 
comment on this tentative conclusion and on the specific proposals 
below. In addition to enhancing reporting requirements for providers 
and improving information sharing with 911 Authorities, we seek comment 
on whether we should establish a dedicated consumer portal for 911-
related outage complaints. Such a portal could provide the public with 
a clear and accessible means to report concerns about 911 service 
disruptions directly to the FCC. This approach may improve the 
Commission's ability to identify and address potential risks to NG911 
reliability while empowering consumers to play a more active role in 
ensuring public safety. We invite input on the potential benefits of 
this proposal, including how it could complement existing reporting 
mechanisms and enhance transparency in addressing 911 service 
reliability.
---------------------------------------------------------------------------

    \168\ For example, the Commission's requirements for live call 
data reporting provide a reduced reporting schedule for non-
nationwide CMRS providers. 47 CFR 9.10(i)(3)(ii)(D).
---------------------------------------------------------------------------

1. Reform of Reliability Certification Process
    Traditionally, NG911 CSPs select ``alternative measures'' to report 
reliability practices that differ from the legacy 911-specific best 
practice benchmarks articulated in our existing regulations, but which 
the Commission deemed reliable in the 2015 Reliability Recon. 
Order.\169\ We seek comment on whether one potential improvement from 
today's proposed changes of both defining NG911 equivalents and 
functional equivalents and codifying the best practice measures 
applicable to IP-based networks would be allowing NG911 CSPs to 
directly certify that they meet the benchmarks specified in our 
regulations, instead of having to use the alternative measures option 
to report IP-based network reliability practices. We seek comment on 
the impact of this change, and on related proposed minor changes 
described below.
---------------------------------------------------------------------------

    \169\ 2015 Reliability Recon. Order, 30 FCC Rcd at 8656-57, 
paras. 12, 15.
---------------------------------------------------------------------------

    In 2015, the Commission observed that NG911 networks achieve 
reliability and resiliency with geographic diversity and dynamic 
routing instead of traditional TDM circuit auditing and tagging, so the 
existing 911 reliability certification rules did not apply well to

[[Page 23788]]

NG911 networks.\170\ The Commission similarly observed that the 
existing monitoring benchmark was appropriate for legacy 911 facilities 
but not IP facilities, as IP-based service providers do not ``audit'' 
monitoring circuits the way TDM providers do, but rather use the 
automated network monitoring capabilities for their resilient IP-
enabled networks.'' \171\ At the time, the Commission did not undertake 
revision of the certification form, but rather instructed NG911 CSPs to 
report that they are using ``alternative measures'' for reliable IP 
best practices, since the CSPs could not realistically certify to using 
TDM-specific best practices on IP networks.\172\ Accordingly, NG911 
providers currently answer the legacy 911 certification questions in 
the negative, but then provide narrative descriptions of how IP network 
reliability differs from legacy 911 reliability.\173\
---------------------------------------------------------------------------

    \170\ 2015 Reliability Recon. Order, 30 FCC Rcd at 8656, para. 
15 (``The circuit auditing requirement adopted in the 911 
Reliability Order was based upon a CSRIC best practice urging 
network operators to `periodically audit the physical and logical 
diversity . . . of their network segment(s) . . . .' [H]owever, 
appropriate measures to preserve physical and logical diversity may 
differ between circuit-switched time division multiplexing (TDM) and 
IP-based networks because IP-based routing and . . . re-routing can 
occur dynamically over many possible paths.'').

12 (``[W]e clarify that the certification framework adopted in the 
911 Reliability Order allows flexibility for all Covered 911 Service 
Providers--legacy and IP-based--to certify reasonable alternative 
measures to mitigate the risk of failure in lieu of specified 
certification elements.''); 2015 Reliability Recon. Order, 30 FCC 
Rcd at 8657, para. 16 (``Technology transitions have already 
resulted in a variety of hybrid 911 network architectures in which 
some functions are provided over legacy TDM circuits and others are 
provided over IP-based infrastructure. In such cases, our rules as 
revised will permit the provider to certify reasonable alternative 
measures with respect to either portion of the network.'').

. . .'').
---------------------------------------------------------------------------

    We seek comment on whether specifying NG911 and IP-based network 
benchmarks directly in the rules will allow NG911 CSPs to more easily 
certify to meeting reasonable reliability best practices without having 
to describe alternative measures for the compliant IP-based network 
facilities they operate, reserving alternative measures for deviations 
from the best practice benchmarks. If so, will this proposed change 
improve Commission collection and analysis of certification reliability 
data? What are the pros and cons of this approach in terms of data 
reported and collected? What drawbacks are there to this approach? 
Should the certification form be revised to require drop-down 
selections for the kind of legacy or NG911 facilities being certified 
to (e.g., selective router central office, path from selective router 
to central office serving PSAP, major transport path to ESInet, LIS 
facility, etc.) to ensure clarity of which best practice standard 
(legacy or NG911) is being certified to? \174\ We propose to direct 
PSHSB to consider revisions the certification form so that CSPs can 
specify which type(s) of 911 facilities they are operating--legacy and/
or NG911--in a way that constrains which best practice standard they 
are certifying to. We further direct PSHSB to consider revisions to the 
certification form in ways that will ensure NG911 CSPs do not have to 
submit narrative explanations of alternative measures for IP-based 
facilities if those facilities meet the regulatory best practice 
benchmarks for IP-based networks. Will this change help the Commission 
identify which filers are proving NG911 services, which are providing 
legacy 911 services, and which are providing both? Would these changes 
also reduce the number of times CSPs have to answer portions of the 
certification form with ``not applicable,'' if the kind of facilities 
they operate and select from the drop-down menu automatically constrain 
which reliability and interoperability benchmarks they may certify to? 
We seek comment on these assessment and proposals.

Reliability Certification System, PS Docket Nos. 15-80, 13-75, 
Public Notice, 35 FCC Rcd 4409, 4413 (seeking comment on adding 
``drop-down fields to 911 reliability certifications that will 
require covered 911 service providers to indicate whether they 
provide'' specified 911, E911, or NG911 services) (PSHSB 2020).
---------------------------------------------------------------------------

    Accordingly, we propose to direct PSHSB to revise the reliability 
and interoperability certification form to replace the current free-
form text reporting option for alternative measures or ``not 
applicable'' answers with specified drop-down selection answers as 
determined by the Bureau, and to seek comment on a revised 
certification form. We tentatively conclude that this approach will 
best illuminate network practices for Commission staff and potentially 
reduce burdens on CSP filers. Similarly, if the updated form asks CSPs 
to select alternative measures and then list all facilities that employ 
them instead of vice-versa as it is now, we believe this will also 
improve reporting. We seek comment on this proposal.
    We further propose modifying the certification form to ask NG911 
CSPs to report on the volume of 911 call traffic that their non-
conforming facilities handle. In response to a previous request for 
comment,\175\ state government parties suggested improvements to the 
certification system to enable the Commission to determine the size of 
potentially impacted populations from critical 911 facility 
failures.\176\ We believe most CSPs handling NG911 traffic from 
multiple OSPs have this data readily available,\177\ and so such 
reporting would constitute a minimal burden to providers while 
providing valuable data to the Commission and to 911 Authorities.\178\ 
We therefore believe such a change would improve 911 reliability and 
oversight with minimal additional burden on regulated entities. We seek 
comment on this proposal, on the best metric and reporting format to 
use for 911 traffic volume data, and on any additional suggestions for 
improving the certification form. Should the proposal be expanded to 
require 911

traffic volume reporting for conforming facilities as well?

---------------------------------------------------------------------------

    We further propose to direct the Bureau to consider additional ways 
to improve the certification forms pursuant to its delegated 
authority.\179\ The 911 reliability and interoperability certification 
submission form and data should simultaneously: (1) ensure the Bureau 
can reasonably perform its investigation \180\ and Remediation Order 
\181\ delegated responsibilities to facilitate 911 reliability and 
interoperability; (2) provide similar reasonable oversight for 911 
Authorities; and (3) impose no greater reporting burdens on CSPs than 
is necessary for these purposes. We direct the Bureau to prepare to 
appropriately implement such improvements bearing these factors in 
mind, consistent with today's rule proposals.
---------------------------------------------------------------------------

    \179\ 47 CFR 0.392(j) (``The Chief of the Public Safety and 
Homeland Security Bureau is delegated authority to . . . develop and 
revise forms and procedures as may be required for the

---------------------------------------------------------------------------

    In connection with the above, we propose minor amendments to 
consolidate rule 9.19 in some instances, to minimize the burden on 
regulated entities subject to these rules by making it easier for them 
to identify and comply with all 911 reliability and interoperability 
requirements. For example, propose to consolidate the alternative 
measures reporting paragraphs at Sec.  9.19(c)(1) to (3) to similarly 
capture both legacy and NG911 providers, and to better ensure the 
Bureau can revise the annual certification form to best respond to 911 
Authorities' needs and obtain necessary data to make a reasonableness 
determination under its delegated authority.\182\ We also propose to 
consolidate and streamline the record retention paragraphs under Sec.  
9.19(d)(3) to better apply across all legacy and NG911 CSPs. We seek 
comment on these modifications, and any other advisable non-substantive 
or conforming edits to rule 9.19.
---------------------------------------------------------------------------

    \182\ 47 CFR 0.392(j).
---------------------------------------------------------------------------

    Finally, we seek comment on whether there are measures in addition 
to annual certification that would promote 911 reliability and 
interoperability. For example, could the Commission implement an 
outcome-based standard that establishes how many annual user minutes of 
911 traffic could be interrupted by network or facility outages and 
still be considered reasonable, beneath which a CSP is subject to 
remediation orders? Could the Commission adopt a similar 
interoperability standard based on percentage of interstate 911 call 
transfers which fail completely, or fail to include caller location or 
other data?
2. Access to Reliability Certifications
    We propose amending the rules to provide that any 911 Authorities 
are entitled to receive, upon request to the CSP, the annual 
reliability and interoperability certifications filed with the 
Commission directly from CSPs operating in their jurisdictions. 
Furthermore, we propose to adopt the same process for NORS access that 
state and local governments may follow for access to the 911 
reliability and interoperability certificate system. Accordingly, 911 
Authorities will have options for accessing 911 reliability and 
interoperability certification data, and may use the option that best 
suits their local needs and relationships with CSPs. We seek comment on 
these proposals.
    Under existing rules, 911 reliability certifications are 
presumptively confidential.\183\ The Commission adopted the rule in 
2013 after balancing the interests of CSPs to protect proprietary and 
sensitive information and the public's access to 911 reliability 
information.\184\ The Commission recognized that ``PSAPs and state 911 
authorities have a strong interest in obtaining relevant information 
about the reliability and resiliency of their 911 service.'' \185\ The 
Commission noted that PSAPs identified a limited set of information 
they believed to be important in assessing reliability of their service 
(e.g., circuit audits), and accordingly, the Commission found no reason 
to address the need for disclosure of additional information to PSAPs 
and/or state 911 authorities.\186\ Nonetheless, the Commission expected 
that CSPs ``will, at the request of the PSAP (or state 911 authority, 
as relevant), enter into discussions concerning the content of the 
provider's 911 circuit auditing certification with respect to the 
PSAP.'' \187\ In light of the wide variety of circumstances involved in 
how PSAPs nationwide purchase 911 service, the Commission declined ``to 
require specific disclosure by rule, preferring to allow parties to 
negotiate reasonable and appropriate terms for assuring protection of 
proprietary information.'' \188\ The Commission made clear, however, 
that CSPs ``should respond promptly to a PSAP request in this area'' 
and reiterated its belief ``that PSAPs should have access to the 
details of circuit-auditing certifications, as long as the sensitive 
and proprietary nature of the information can be maintained.'' \189\
---------------------------------------------------------------------------

    \183\ Specifically, Rule 0.457(d)(1)(viii) states: ``Information 
submitted with a 911 reliability certification pursuant to 47 CFR 
12.4 [now 47 CFR 9.19] that consists of descriptions and 
documentation of alternative measures to mitigate the risks of 
nonconformance with certification elements, information detailing 
specific corrective actions taken with respect to certification 
elements, or supplemental information requested by the Commission 
with respect to such certification.'' 47 CFR 0.457(d)(1)(viii). See 
47 CFR 9.19(d)(2)(i) and (ii).
    \184\ 911 Reliability Order, 28 FCC Rcd at 17533, paras. 157-
158.
    \185\ For example, NENA stated that ``PSAPs may be in the best 
position to use this information to prompt 911 service providers to 
make specific reliability improvements in their networks, but they 
may not otherwise be able to negotiate reliable access to this 
information through their contracts or tariffs.'' 911 Reliability 
Order, 28 FCC Rcd at 17533, para. 157.

---------------------------------------------------------------------------

    We seek comment on whether there is an increased need for state and 
local government access to 911 reliability and interoperability 
certification data today, particularly in light of the advancing NG911 
transition and the new roles being adopted by 911 Authorities and 
private network operators. Do other changes in network architecture 
evolution also change the need for state and local access to Commission 
data concerning 911 reliability and interoperability? For example in 
2021, the Commission concluded that directly sharing NORS data with 
state and federal agencies, subject to appropriate and sufficient 
safeguards, is in the public interest, and the Commission extended this 
finding to include the sharing of DIRS data.\190\ The

[[Page 23790]]

Commission limited eligibility for direct access to our NORS and DIRS 
databases to ``need to know'' agencies acting on behalf of the federal 
government, the 50 states, the District of Columbia, Tribal Nations, 
and the U.S. territories.\191\ In discussing sharing of complete NORS 
and DIRS reports and filings, the Commission noted ``that sympathy 
reports and reports containing information about TSPs contain 
actionable information on outages that could be of use to public safety 
officials for emergency response or service restoration and declined to 
exclude these reports from NORS filings. For example, sympathy reports 
contain information regarding service outages that, while caused by a 
failure in the network of another provider, nonetheless have an effect 
on the reporting service provider that may have public safety 
implications.'' \192\
---------------------------------------------------------------------------

    \190\ See NORS Information Sharing Order, 36 FCC Rcd 6136. By 
way of background, the Commission collects network outage 
information in the Network Outage Reporting System (NORS) and 
infrastructure status information in the Disaster Information 
Reporting System (DIRS). This information is sensitive for reasons 
concerning national security and commercial competitiveness, and the 
Commission thus treats it as presumptively confidential. The 
Commission makes this information available to the Department of 
Homeland Security's (DHS) National Cybersecurity and Communications 
Integration Center but does not share the information more broadly 
with other federal, state, or local partners. New Part 4 of the 
Commission's Rules Concerning Disruptions to Communications, ET 
Docket No. 04-35, Report and Order and Further Notice of Proposed 
Rulemaking, 19 FCC Rcd 16830, 16856, para. 47 (2004), 69 FR 68859 
(Nov. 26, 2004), 69 FR 70316 (Dec. 3, 2004) (making NORS reports 
available to DHS ``in encrypted form and immediately upon 
receipt'').

---------------------------------------------------------------------------

    Under our proposal, we would retain the existing requirements under 
Sec.  9.19(d)(2)(i) and (ii), but would add that 911 Authorities will 
be eligible to accessing the 911 reliability and interoperability 
certification database under the same conditions as NORS access, and 
also require CSPs to provide their annual certifications to 911 
Authorities in their CSP service areas upon the request of a 911 
Authority.\193\ For example, if a 911 Authority issues a request to 
contacts a CSP, including a CSP that delivers 911 traffic to the in-
state NG911 Delivery Point, the CSP would be required to provide the 
information applicable to that 911 Authority and within that 911 
Authority's jurisdiction. We believe that 911 Authorities have a strong 
interest in accessing certification filings to ensure the reliability 
of 911 traffic in their jurisdictions during the NG911 transition.\194\ 
In addition, we believe 911 Authorities would benefit from having 911 
reliability and interoperability certifications to assist with 
developing emergency response plans in advance of an outage.
---------------------------------------------------------------------------

    \193\ In that connection, we would also retain the existing 
record retention requirements under 47 CFR 9.19(d)(3) with updates 
to cover interoperability certifications and streamlining as noted 
above.
    \194\ See, e.g., Washington Utilities and Transportation 
Commission Comments, PS Docket No. 14-193, p. 8 (filed March 17, 
2015) (``Additionally, as part of the cooperative framework with 
state and local partners the Commission seeks to maintain, the UTC 
suggests the proposed expanded certification requirements of Rule 
12.4 be modified to require that all covered entities that submit 
annual certification, compliance, or audit reports, should also be 
required to simultaneously submit such information to designated 
state governance officials, such as the UTC and the Washington State 
E911 Coordinator's Office, that are actively involved or have some 
oversight responsibilities with respect to reliable 911 service 
delivery at the state level. Access to such information by state 
officials would greatly assist in understanding and tracking 
marketplace developments affecting 911 service delivery within the 
scope of their jurisdictions. State access could also greatly assist 
officials during times of emergency, like the April 2014 multi-state 
outage, in understanding and interacting with such entities as 
events unfold. The UTC urges the Commission to modify the 
certification and reporting requirements of Rule 12.4 by requiring 
covered 911 service providers to submit certification and compliance 
information and reports to the Commission's state partners.'').
---------------------------------------------------------------------------

    We acknowledge that certifications are presumptively confidential 
under our existing rules, and CSPs and 911 Authorities must agree to 
confidentiality for sharing certifications. Under today's proposed 
approach, CSPs must share relevant portions of certifications, but may 
omit or redact information relating to portions of their networks that 
are not located within and not providing any service directly to the 
requesting 911 Authority's jurisdiction. CSPs may condition providing 
their certifications on the 911 Authority executing a confidentiality 
agreement.
    We also propose extending our NORS/DIRS information sharing 
framework to 911 reliability and interoperability certifications to 911 
Authorities only. 911 Authorities who prefer not to request 
confidential certifications directly from CSPs may request access to 
certifications from the Bureau under the same terms currently provided 
under rule 4.2.\195\ CSPs receiving a request to provide a 
certification to a 911 Authority must provide it within 14 days under 
confidentiality terms no more restrictive than the same rule.\196\ We 
seek comment on whether this proposal would best help ensure 911 
Authorities' access to valuable information. Would this proposal 
incentivize cooperation between states and CSPs? Do 911 Authorities 
prefer having the option to seek this information either directly from 
CSPs or from PSHSB? We seek comment on this proposal and any 
alternatives.
---------------------------------------------------------------------------

    \195\ 47 CFR 4.2.
    \196\ To protect sensitive communications status data, 
Participating Agencies and Downstream Agencies must preserve the 
confidentiality of certification filings. The Commission will grant 
access to certification filings only after 911 Authorities certify 
that they will comply with requirements for maintaining the 
confidentiality of the data and the security of the databases. 911 
Authorities will also be responsible for ensuring downstream 
agencies certify that they, too, will maintain the confidentiality 
of the data they receive. See 47 CFR 4.2.
---------------------------------------------------------------------------

    Finally, we propose to amend Sec.  9.19(d) of the rules to require 
CSPs to notify their 911 Authority of cessation of service at the same 
time they notify the Commission. Under our current rules, CSPs that 
cease covered operations under this section must notify the FCC by 
filing a notification under penalty of perjury no later than 60 days 
after the cessation of service.\197\ For the reasons discussed above, 
we believe that 911 Authorities would benefit from having situational 
awareness of when CSPs cease providing services to their jurisdictions, 
and seek comment on this proposal, including alternatives, and 
potential costs to CSPs.
