Abstract

In this document, the Federal Communications Commission (the FCC or Commission) adopted a Report and Order to advance the nationwide Next Generation 911 (NG911) transition rules that define the responsibilities and set deadlines for originating service providers (OSPs) to implement NG911 capabilities on their networks and deliver 911 calls to NG911 systems established by 911 authorities. In addition, the rules preserve the authority of state, territorial, regional, Tribal, and local government to adopt alternative approaches to the configuration, timing, and cost responsibility for NG911 implementation within their jurisdictions.

Synopsis

I. Introduction

    This document is a summary of the Commission's Report and Order 
(Order). In the Order, we take steps that will advance the nationwide 
transition to Next Generation 911 (NG911). Like communications networks 
generally, dedicated 911 networks are evolving from Time Division 
Multiplexing (TDM)-based circuit-switched architectures to internet 
Protocol (IP)-based architectures. With the transition to NG911, legacy 
911 networks will be replaced by IP-based technologies and 
applications, which provide new capabilities and improved 
interoperability and system resilience. Most states have begun to 
invest significantly in NG911, but some have experienced delays in 
communications providers connecting to these IP-based networks. As a 
result of these delays, state and local 911 authorities incur prolonged 
costs because of the need to maintain both legacy and IP networks 
during the transition. Managing 911 traffic on both legacy and IP 
networks at the same time may also result in increased vulnerability 
and risk of 911 outages.
    To facilitate the NG911 transition, we adopt rules that will 
require wireline providers, Commercial Mobile Radio Service (CMRS) 
providers, covered text providers, providers of interconnected Voice 
over internet Protocol (VoIP) services, and providers of internet-based 
Telecommunications Relay Service (internet-based TRS) (collectively 
``originating service providers'' or ``OSPs'') \1\ to take actions to 
start or continue the transition to NG911 in coordination with 911 
Authorities.\2\ The rules 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.
---------------------------------------------------------------------------

    \1\ For purposes of this document and the Order and the rules we 
adopt, ``wireline provider'' means ``[a] local exchange carrier (as 
defined in 47 U.S.C. 153(32)) that provides service using wire 
communication (as defined in 47 U.S.C. 153(59)),'' and ``covered 
text provider'' has the meaning given such term under 47 CFR 
9.10(q)(1). The terms ``CMRS,'' ``interconnected VoIP service,'' and 
``internet-based TRS'' have the meanings identified in 47 CFR 9.3.
    \2\ ``911 Authority'' means ``[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.''
---------------------------------------------------------------------------

    We implement a two-phased approach to guide the transition to 
NG911. Each phase is initiated by a 911 Authority submitting a valid 
request to OSPs within the jurisdiction where the 911 Authority is 
located for the OSPs to comply with NG911 requirements, including:
    <bullet> Phase 1: Upon receiving a valid Phase 1 request from a 911 
Authority, an OSP must commence delivery of 911 traffic in IP-based 
Session Initiation Protocol (SIP) format to one or more in-state NG911 
Delivery Points designated by the 911 Authority. Phase 1 will enable 
911 Authorities to deploy Emergency Services IP Networks (ESInets) in a 
cost-effective manner by selecting convenient delivery points to 
receive 911 traffic; will improve 911 reliability by using an IP-based 
format, rather than legacy format, to deliver 911 traffic; and will 
establish the transmission platforms necessary for upgrading to Phase 
2.
    <bullet> Phase 2: Upon receiving a valid Phase 2 request from a 911 
Authority, an OSP must commence delivery of 911 traffic to the 
designated in-state NG911 Delivery Point(s) in an IP-based SIP format 
that complies with NG911 commonly accepted standards identified by the 
911 Authority, including having location information embedded in the 
call signaling using Presence Information Data Format--Location Object 
(PIDF-LO) \3\ or the functional equivalent. In Phase 2, the OSP must 
install and put into operation all equipment, software applications, 
and other infrastructure, or acquire all services, necessary to use a 
Location Information Server (LIS) or its functional equivalent for the 
verification of its customer location information and records.\4\ Phase 
2 will facilitate use of

[[Page 78067]]

the functional elements of Next Generation 911 Core Services (NGCS), 
which can deliver dynamic information to Public Safety Answering Points 
(PSAPs), enabling them to use policy routing functions to dynamically 
reroute 911 traffic to avoid network disruptions, thus reducing the 
impact of outages on 911 continuity.
---------------------------------------------------------------------------

    \3\ See Internet Engineering Task Force (IETF), Dynamic 
Extensions to the Presence Information Data Format Location Object 
(PIDF-LO) (Sept. 2010), <a href="https://datatracker.ietf.org/doc/html/rfc5962">https://datatracker.ietf.org/doc/html/rfc5962</a> (RFC 5962), and A Presence-based GEOPRIV Location Object 
Format (Dec. 2005), <a href="https://datatracker.ietf.org/doc/html/rfc4119">https://datatracker.ietf.org/doc/html/rfc4119</a> 
(RFC 4119).
    \4\ ``Location Information Server (LIS)'' means ``[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.''
---------------------------------------------------------------------------

    For both Phase 1 and Phase 2, 911 Authorities must meet specific 
readiness criteria in order to make a valid request for OSP delivery of 
NG911 traffic. For Phase 1, the 911 Authority must certify that it has 
all the necessary infrastructure installed and operational to receive 
911 traffic in SIP format and to transmit such traffic to the PSAPs 
connected to it. The 911 Authority must also identify the NG911 
Delivery Points that it has designated and notify the OSP(s) of these 
delivery points via a registry or direct written notification. For 
Phase 2, the 911 Authority must certify: (1) that it has all of the 
necessary infrastructure installed and operational to receive 911 
traffic in SIP format that complies with NG911 commonly accepted 
standards and to transmit such traffic to the PSAPs connected to it; 
and (2) that its ESInet is connected to a fully functioning NGCS 
network that can provide access to a Location Validation Function (LVF) 
and interface with the LIS or functional equivalent provided by the 
OSP.\5\
---------------------------------------------------------------------------

    \5\ In the NG911 environment, a LVF works with the LIS to 
validate the location of a civic address prior to a call being 
placed to 911. See, e.g., NENA: The 9-1-1 Association (NENA), The 
Next Generation 9-1-1 Guide for 9-1-1 Authorities at 38 (Apr. 21, 
2020) <a href="https://cdn.ymaws.com/www.nena.org/resource/resmgr/standards/nena-ref-005.1-2020_ng911_gu.pdf">https://cdn.ymaws.com/www.nena.org/resource/resmgr/standards/nena-ref-005.1-2020_ng911_gu.pdf</a> (NENA NG911 Guide for 911 
Authorities). The functionality of the LVF within NG911 replaces the 
E911 master street address guide (MSAG) validation in legacy 911 
environments. Id. In this document and the Order, we define 
``Location Validation Function'' (LVF) as ``[a] Functional Element 
in an NG911 Core Services (NGCS) consisting of a server where civic 
location information is validated against the authoritative 
Geographic Information System (GIS) database information. A civic 
address is considered valid if it can be located within the database 
uniquely, is suitable to provide an accurate route for an emergency 
call, and is adequate and specific enough to direct responders to 
the right location.''
---------------------------------------------------------------------------

    Nationwide CMRS providers,\6\ covered text providers,\7\ 
interconnected VoIP providers, and wireline providers other than rural 
incumbent local exchange carriers (RLECs) will have six months 
following a 911 Authority's valid Phase 1 request to comply with Phase 
1 requirements, and six months following a valid Phase 2 request to 
comply with Phase 2 requirements. RLECs,\8\ non-nationwide CMRS 
providers,\9\ and internet-based TRS providers will have one year 
following a 911 Authority's valid Phase 1 request to comply with Phase 
1 requirements, and one year following a valid Phase 2 request to 
comply with Phase 2 requirements. Completion of Phase 1 is a 
prerequisite to commencement of Phase 2; however, if Phase 1 has 
already been achieved or an OSP completes Phase 1 in less than the 
allotted six-month or one-year period, the Phase 2 implementation 
period can commence immediately, provided the 911 Authority has met the 
Phase 2 readiness criteria. To facilitate collaboration between 911 
Authorities and OSPs, we also permit 911 Authorities and OSPs to enter 
into mutual agreements that modify the Phase 1/Phase 2 terms and 
timelines, and our rules presumptively do not alter or invalidate such 
agreements that already exist.
---------------------------------------------------------------------------

    \6\ The term ``nationwide CMRS provider'' has the meaning given 
such term under 47 CFR 9.10(i)(1)(iv).
    \7\ The term ``covered text provider'' has the meaning given 
such term under 47 CFR 9.10(q)(1).
    \8\ ``Rural incumbent local exchange carrier (RLEC)'' has the 
meaning given such term under 47 CFR 54.5.
    \9\ A ``non-nationwide CMRS provider'' has the meaning given 
such term under 47 CFR 9.10(i)(1)(v).
---------------------------------------------------------------------------

    The rules presumptively address cost allocation between OSPs and 
911 Authorities for implementation of NG911. In the absence of an 
alternative cost arrangement implemented by a 911 Authority at the 
state or local level, OSPs will be financially responsible for the 
costs of transmitting 911 traffic to the NG911 Delivery Points 
designated by 911 Authorities starting at Phase 1. Thus, by default, 
our rules establish NG911 Delivery Points as the demarcation points 
where the OSP's responsibility for the cost of transmitting 911 traffic 
ends and the 911 Authority's responsibility begins. In addition, in 
both Phase 1 and Phase 2, OSPs will be presumptively responsible for 
the costs associated with translating 911 traffic into the required IP-
based format, including associated routing and location information.
    The rules are intended to expedite the NG911 transition and help 
ensure that the nation's 911 system functions effectively and reliably, 
with advanced capabilities. In addition, the rules respond to the 
petition filed in 2021 by the National Association of State 911 
Administrators (NASNA),\10\ which urged the Commission to take actions 
to resolve uncertainty and disputes between OSPs and state 911 
Authorities regarding the NG911 transition. The rules create a 
consistent framework for ensuring that OSPs take the necessary steps to 
implement the transition to NG911 capabilities in coordination with 911 
Authorities. At the same time, we recognize and do not preempt the 
long-standing authority of State and local government over the 
provision of 911 service. Thus, 911 Authorities at the State, local, 
and Tribal level remain free to establish alternative provisions within 
their jurisdictions for the implementation of NG911, definition of 
demarcation points, and allocation and recovery of costs.

II. Background

    911 service is a vital part of our nation's emergency response and 
disaster preparedness system. Since the first 911 call was placed in 
1968,\11\ the American public has increasingly come to depend on 911 
service. The National Emergency Number Association (NENA) estimates 
that some form of 911 service is available to over 98 percent of the 
population and to over 97 percent of the counties in the United 
States,\12\ and data collected in our annual 911 fee report indicate 
that over 217 million calls are made to 911 in the United States each 
year.\13\ The availability of this critical service is due largely to 
the dedicated efforts of State, local, territorial, and Tribal 
authorities and providers, who have used the 911 dialing code to 
provide access to increasingly advanced and effective emergency service 
capabilities.\14\

A. 911 Implementation

    The Universal Emergency Number. In 1999, Congress amended section 
251(e) of the Communications Act of 1934, as amended (the Act), and 
directed the Commission to designate ``911'' as the nationwide 
abbreviated dialing code for wireline and wireless voice services in 
order to obtain public safety and emergency services.\15\ In 2000, the

[[Page 78068]]

Commission designated 911 as the national emergency telephone number to 
be used for reporting emergencies and requesting emergency 
assistance.\16\ In 2001, the Commission established a period for 
wireline and wireless carriers to transition to routing 911 calls to a 
PSAP in areas where one had been designated or, in areas where a PSAP 
had not yet been designated, either to an existing statewide default 
point or to an appropriate local emergency authority.\17\

(codified at 47 U.S.C. 251(e)(3)). The purpose of the 911 Act is to 
enhance public safety by encouraging and facilitating the prompt 
deployment of a nationwide, seamless communications infrastructure 
for emergency services that includes wireless communications. 911 
Implementation Notice, 15 FCC Rcd at 17081, para. 1 (citing 911 Act

communications throughout the United States so that all 
jurisdictions offer seamless networks for prompt emergency service.

64.3001 the obligation of telecommunications carriers to transmit 
all 911 calls to a PSAP, to a designated statewide default answering 
point, or to an appropriate local emergency authority. Id. In 
addition, the Commission codified in former Sec.  64.3002 the 
periods for transition to 911 as the universal emergency telephone 
number. Id. The Commission subsequently renumbered Sec. Sec.  
64.3001 and 64.3002 as current Sec. Sec.  9.4 and 9.5, respectively.

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

    Legacy 911 Call Routing. In legacy E911 systems, 911 calls are 
typically routed through the use of a wireline network element--called 
a selective router--to a geographically appropriate PSAP based on the 
caller's location.\18\ The selective router serves as the entry point 
for wireline 911 calls originated from competitive and incumbent Local 
Exchange Carrier (LEC) central offices over dedicated trunks,\19\ as 
well as 911 calls originated by wireless \20\ and interconnected VoIP 
\21\ callers that are delivered by wireless and interconnected VoIP 
networks to the selective router. In legacy architectures, PSAPs are 
connected to telephone switches in the selective router by dedicated 
trunk lines.\22\ Historically, the selective router and connecting 
trunk lines have been implemented, operated, and maintained by a subset 
of incumbent LECs and largely paid for by state or local 911 
authorities through state tariffs or contracts.\23\ Network 
implementation has varied from carrier to carrier and jurisdiction to 
jurisdiction, but legacy E911 has typically been based on traditional 
circuit-switched architecture and implemented with legacy components 
that place significant limitations on the functions that can be 
performed over the network.\24\ Below is a simplified diagram that 
demonstrates legacy 911 architecture.

Corp. v. FCC, 473 F.3d 302 (D.C. Cir. 2006). In the event a 911 
Authority has only implemented basic 911, or utilizes a standalone 
ANI/ALI database, the 911 Authority may or may not utilize selective 
routers in its architecture. See Letter from Alexandra Mays, 
Assistant General Counsel & Director, Regulatory Affairs,

    Legacy Demarcation Point. Although the Commission has not 
previously set a cost demarcation point for wireline, interconnected 
VoIP, or internet-based TRS providers in the E911 environment, the 
Commission has set a demarcation point for purposes of the wireless 
transition to E911. Early in the implementation of E911 Phase I by 
wireless carriers, King County, Washington sought clarification of the 
demarcation point for costs in wireless

[[Page 78069]]

E911 Phase I implementation.\25\ In 2001, the Wireless 
Telecommunications Bureau (WTB) issued a decision (King County Letter) 
identifying the input to the 911 selective router maintained by the 
incumbent LEC as the ``proper demarcation point'' for allocating 
wireless E911 Phase I information delivery responsibilities and costs 
in instances when CMRS providers and 911 authorities could not agree on 
an appropriate demarcation point.\26\ In 2002, the Commission issued an 
Order on Reconsideration (King County Order on Reconsideration) 
affirming WTB's decision.\27\ The Commission affirmed that for a 
wireless carrier to satisfy its obligation to provide E911 Phase I 
information to the PSAP under section 20.18(d) (now section 9.10(d)), 
the wireless carrier must deliver and bear the costs to deliver E911 
Phase I information to the equipment in the existing 911 system that 
``analyzes and distributes it,'' i.e., the 911 selective router.\28\ 
The Commission also affirmed that PSAPs were required to bear E911 
Phase I costs for delivery beyond the 911 selective router.\29\ 
Finally, the Commission extended this determination to apply to CMRS 
providers' delivery of wireless E911 Phase II information to selective 
routers.\30\ Together, these decisions provided guidance to facilitate 
implementation of E911 in TDM networks. However, the Commission has not 
previously sought to address the demarcation of service providers' cost 
responsibilities in the NG911 environment.

    Interconnected Voice Over Internet Protocol (VoIP). Regarding 
interconnected VoIP, the Commission has recognized that consumers 
expect certain types of emerging voice technology to have the same 
ability to reach emergency services when dialing 911 as traditional 
wireline and wireless services.\31\ This recognition resulted in the 
2005 VoIP 911 Order, in which the Commission imposed 911 service 
obligations on providers of interconnected VoIP.\32\ The Commission 
declined to establish an E911 demarcation point for interconnected VoIP 
service, but it stated that ``[t]o the extent that it becomes a 
concern, we believe that the demarcation point that the Commission 
established for wireless E911 cost allocation would be equally 
appropriate for VoIP.'' \33\

(defining interconnected VoIP service), 9.11-9.12 (giving 
interconnected VoIP providers duties and rights with respect to 
provision of 911 service). The Commission later clarified that the 
911 VoIP requirements extended to ``outbound only'' interconnected 
VoIP providers, that is, VoIP providers that permit users to 
initiate calls that terminate to the PSTN even if they do not also 
allow users to receive calls from the PSTN. Kari's Law/RAY BAUM'S 
Act Order, 34 FCC Rcd at 6670-71, 6675, paras. 174, 183. While 
section 615b uses the term ``IP-enabled voice service,'' it defines 
this term as having the same meaning as ``interconnected VoIP'' in 
Sec.  9.3 of the Commission's rules. 47 U.S.C. 615b(8). We refer to 
both of these terms in this document and the Order as 
``interconnected VoIP service'' (and to providers of such a service 
as ``interconnected VoIP providers'') and in doing so intend to 
encompass all VoIP services subject to 911 obligations under part 9 
of our rules, including providers of internet Protocol Captioned 
Telephone Service (IP CTS), who are also the providers of the 
associated interconnected VoIP service. IP CTS is a form of 
Telecommunications Relay Service (TRS) ``that permits an individual 
with a hearing or a speech disability to communicate in text using 
an internet Protocol-enabled device via the internet, rather than 
using a text telephone (TTY) and the public switched telephone 
network.'' 47 CFR 64.601(a)(24). We also include other providers of 
internet-based TRS, video relay service (VRS), and Internet Protocol 
Relay Service (IP Relay).

    911 Parity. By 2008, Congress recognized that the nation's 911 
system was ``evolving from its origins in the circuit-switched world 
into an IP-based network'' \34\ and that for interconnected VoIP 
providers to fulfill their 911 service obligations to subscribers, they 
must have access to the same emergency services capabilities and 
infrastructure as other voice providers.\35\ Congress passed the New 
and Emerging Technologies Improvement Act of 2008 (NET 911 Act) to 
facilitate the rapid deployment of VoIP 911 services and encourage the 
transition to a national IP-enabled emergency network.\36\ The NET 911 
Act extended critical 911 service-related rights, protections, and 
obligations to VoIP service providers,\37\ and mandated parity for VoIP 
providers vis-[agrave]-vis other voice providers subject to 911 
obligations with respect to the rates, terms, and conditions applicable 
to exercising their rights and obligations to provision VoIP 911 
service.\38\

B. Transition to Next Generation 911

1. Legal and Policy Landscape
    Like communications networks generally, 911 networks are evolving 
from TDM-based architectures to IP-based architectures. With the 
transition to NG911, the circuit-switched architecture of legacy 911 
will eventually be entirely replaced by IP-based technologies and 
applications that provide all of the same functions as the legacy 911 
system, as well as new capabilities. 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 by individuals seeking emergency 
assistance.\39\
---------------------------------------------------------------------------

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

    Congress has recognized the Commission's role in facilitating the 
transition to NG911. As part of the 2010 National Broadband Plan, the 
Commission recommended that Congress consider developing a new ``legal 
and regulatory framework for development of NG911 and the transition 
from legacy 911 to NG911 networks.'' \40\ Also in 2010, Congress 
enacted the Twenty-First Century Communications and Video Accessibility 
Act (CVAA), which authorized the Commission to implement regulations 
necessary to achieve reliable and interoperable communication that 
ensures access to

[[Page 78070]]

an IP-enabled emergency network by individuals with disabilities, where 
achievable and technically feasible.\41\ In 2012, Congress enacted the 
Next Generation 9-1-1 Advancement Act of 2012 (NG911 Act) as part of 
the Middle Class Tax Relief and Job Creation Act of 2012, and directed 
the Commission to prepare and submit a report to Congress on 
recommendations for the legal and statutory framework for NG911 
services.\42\ In 2013, the Commission submitted that report, 
recommending among other things that Congress: (1) facilitate the 
exercise of existing authority over NG911 by certain federal agencies 
(including the Commission); and (2) consider enacting legislation that 
would ensure there is no gap between federal and state authority over 
NG911.\43\ The Commission stated that ``[t]he Commission already has 
sufficient authority to regulate the 911 and NG911 activity of, inter 
alia, wireline and wireless carriers, interconnected VoIP providers, 
and other IP-based service providers.'' \44\

    The technological and regulatory landscape underlying 911 has 
evolved significantly since 2013. The Commission has adopted 
requirements for text-to-911, real-time text, wireless indoor location 
accuracy, and dispatchable location.\45\ In addition, the Commission 
has updated 911 outage and reliability rules, including establishing 
reliability requirements for covered 911 service providers.\46\ With 
respect to technology, E911 Phase II is now widely implemented,\47\ and 
many state and local jurisdictions have deployed ESInets and taken 
other transitional steps towards NG911.\48\ Although the NG911 
transition remains ongoing and there are no fully enabled NG911 systems 
yet operating,\49\ the technical architecture of NG911 systems has been 
developed in detail and is well-established,\50\ and one service 
provider--Verizon--states that it has achieved end-to-end readiness 
with two local jurisdictions based on the NENA i3 standard.\51\

2. Standards Work and Federal Advisory Committee Reports
    NENA i3 Transitional and End State NG911. The public safety 
community has recognized the need to evolve to NG911, and industry 
associations and standards bodies have worked toward defining standard 
architectures and protocols for NG911. For example, NENA's ``i3'' 
standard describes a system architecture for NG911 that standardizes 
the structure and design of the software services, databases, network 
elements, and interfaces needed to process multimedia emergency calls 
and data for NG911.\52\ The i3 standard is intended to ``support[ ] 
end-to-end IP connectivity,'' while using ``gateways . . . to 
accommodate legacy wireline and wireless originating networks that are 
non-IP as well as legacy PSAPs that interconnect to the i3 solution 
architecture.'' \53\ In addition, NENA i3 addresses the concept of the 
ESInet, ``an IP-based inter-network (network or networks) that can be 
shared by all public safety agencies that may be involved in any 
emergency,'' and identifies ``a set of core services that process 9-1-1 
calls on that network (NGCS-NG9-1-1 Core Services).'' \54\ The i3 
standard envisions that NG911 will reach a mature ``end state'' \55\ 
after all PSAPs have migrated from legacy E911 systems based on TDM 
circuit-switched telephony to all-IP systems that operate over ESInets 
and provide the full array of NGCS.\56\ The standard

[[Page 78071]]

also recognizes that achieving end state NG911 will take time and that 
significant intermediate and transitional mechanisms are needed in the 
interim. Accordingly, the i3 standard provides for Legacy Network 
Gateways (LNGs) and other transitional network elements to ensure that 
TDM-based OSPs can originate 911 calls and that legacy PSAPs can 
receive them while the NG911 transition is ongoing.

7, 2021), <a href="https://cdn.ymaws.com/www.nena.org/resource/resmgr/standards/NENA-STA-010.3e-2021_i3_Stan.pdf">https://cdn.ymaws.com/www.nena.org/resource/resmgr/standards/NENA-STA-010.3e-2021_i3_Stan.pdf</a> (NENA i3). In July 2021, 
NENA released the third version of the i3 standard for NG911. See 
NENA, NENA Releases New Version of the i3 Standard for Next 
Generation 9-1-1 (July 12, 2021) <a href="https://www.nena.org/news/572966/NENA-Releases-New-Version-of-the-i3-Standard-for-Next-Generation-9-1-1.htm">https://www.nena.org/news/572966/NENA-Releases-New-Version-of-the-i3-Standard-for-Next-Generation-9-1-1.htm</a>. In October 2021, the NENA i3 standard was approved by the 
American National Standards Institute (ANSI). See NENA, ANSI 
Approves NENA's i3 Standard for Next Generation 9-1-1 (Oct. 7,

    \53\ NENA i3 at 2.
    \54\ NENA i3 at 2 (footnote omitted).
    \55\ The NENA i3 standard describes how NG911 works after 
transition, including ongoing interworking requirements for IP-based 
and Time Division Multiplexed (TDM)-based PSAPs and originating 
networks. The i3 standard does not provide solutions for how legacy 
PSAPs, originating networks, Selective Routers (SRs), and Automatic 
Location Identification (ALI) systems evolve. Rather, the i3 
standard describes the end state when transition is complete. 
According to the NENA i3 standard, ``[a]t that point, SRs and 
existing ALI systems are decommissioned and all 9-1-1 calls are 
routed using the Emergency Call Routing Function (ECRF) and arrive 
at the ESInet/NGCS via Session Initiation Protocol (SIP).'' NENA i3 
at 2.
    \56\ Id. at 2. To get to this ``end state,'' the NENA i3 
standard observes that it is critical to understand several 
underlying assumptions. For example, ``[a]ll calls entering the 
ESInet are SIP-based. Gateways, if needed, are outside of, or on the 
edge of, the ESInet. Calls that are IP-based, but use a protocol 
other than SIP or are not fully i3-compliant, must be interworked to 
i3-compliant SIP prior to being presented to the ESInet.'' NENA i3 
at 3.
---------------------------------------------------------------------------

    Task Force on Optimal PSAP Architecture. In 2014, the FCC 
established the Task Force on Optimal PSAP Architecture (Task Force or 
TFOPA) to provide recommendations regarding actions that PSAPs can take 
to optimize their security, operations, and funding as they implement 
NG911.\57\ In its Final Report, TFOPA noted that the transition to 
NG911 requires comprehensive changes across the ``Originating Service 
Environment (OSE),'' which includes originating service providers as 
part of a broader environment that provides the 911 caller's location 
as part of the call setup.\58\ This environment includes IP call set-
up, location determination, validation, and delivery to ESInets across 
the country.\59\ In addition, the three TFOPA Working Groups issued 
supplemental reports in 2016 concerning (1) an ``Optimal Cybersecurity 
Approach for PSAPs''; \60\ (2) an ``NG 9-1-1 Readiness Scorecard''; 
\61\ and (3) a ``Funding Sustainment Model.'' \62\

Regarding readiness, TFOPA WG 2, for example, observed that the 
NG911 transition process followed a ``maturity continuum'' ranging 
from a ``legacy state'' through ``foundational, transitional, and 
intermediate'' stages, on the way to a goal of full ``end state'' 
NG911 relative to PSAPs. TFOPA WG 2 Report at 12-14. Specifically, 
the WG 2 Report defined ``Jurisdictional End State'' (noting that a 
jurisdiction could be a Local, Regional, State or Tribal Authority 
and could be intrastate or interstate) as ``the state in which PSAPs 
are served by i3 standards-based systems and/or elements, from 
ingress through multimedia `call' handling. Originating Service 
Providers are providing SIP interfaces and location information 
during call set-up time. Within the jurisdiction, ESInets are 
interconnected providing interoperability which is supported by 
established agreements, policies and procedures. Systems in the End 
State are NG9-1-1 Compliant.'' TFOPA WG 2 Report at 13. Based on 
anecdotal information, including based on ESInet and NG911 early 
adopter case studies, TFOPA WG 2 noted that a ``phased'' 
implementation model offers the greatest opportunity for success, as 
opposed to a one-step implementation. TFOPA WG 2 Report at 12, 76-

    Communications Security, Reliability, and Interoperability Council 
(CSRIC) VI and Small Carrier NG911 Considerations. In 2017, the 
Commission directed CSRIC VI to recommend measures to improve both 
legacy 911 and NG911 systems, including recommending ways in which the 
Commission can further the NG911 transition, enhance the reliability 
and effectiveness of NG911, and assist small originating service 
providers as they transition to providing NG911 service.\63\ The CSRIC 
VI Working Group 1 considered four types of small originating service 
providers: wireless carriers, LECs, television cable operators, and 
internet/Data Service Providers.\64\ The CSRIC NG911 Transition Report 
describes the issues these carriers face as they update their networks 
to support NG911, and it advises the FCC on small carrier concerns 
related to NG911 implementation.\65\ The Transition Report is organized 
into three major sections, dealing with the scope and nature of the 
report; \66\ analysis, findings and recommendations; \67\ and a small 
carrier readiness checklist \68\ structured around service provider 
support for migration to NG911. The report's recommendations relating 
to small carriers address: (1) transition timelines; \69\ (2) the 
regulatory environment; \70\ (3) NG911 funding; \71\ (4) 
interconnection options; \72\ and (5) delivering caller location to the 
NG911 ESInet.\73\ The report includes advice on how small carriers 
should prepare to deliver their 911 traffic in an NG911 compatible 
manner; what economic challenges small carriers may face; and what 
barriers to implementation, if any, the FCC should address.\74\

    \67\ The ``Analysis, Findings and Recommendation'' section 
builds on a review of today's legacy environment and addresses 
service provider interconnection with both transitionary and ``end-
state'' NG9-1-1 systems, call and data related matters, security, 
and regulatory/policy factors. Id. sec. 5.1.
    \68\ The small carrier checklist is structured around three 
stages of small carrier ``readiness'' to support NG9-1-1. Id. sec. 
5.2. Essential ``elements'' of readiness are identified, ranging 
from public safety governance and regulatory matters, to routing and 
location matters, geographic information system (GIS) needs, network 
considerations, security and operational planning requirements. Id.
    \69\ CSRIC advises that small carrier transition timelines will 
vary by carrier depending on the resources they have available to 
focus on the transition and notes that it is important that small 
carriers work with their state or regional 911 Authority to 
coordinate their transition timelines and expectations. Id. sec. 
5.1.6.1.
    \70\ Historically, state and Federal statutes or regulations 
regarding time division multiplex (TDM) network interconnection to a 
legacy 9-1-1 selective router in a particular Local Access and 
Transport Area (LATA) by small carriers has often been based on the 
process for interconnecting with the largest incumbent Local 
Exchange Carrier (ILEC) in an area. Id. sec. 4.1 As traffic exchange 
evolves into full IP environment, regulatory and technical 
expectations and responsibilities may change. Id. sec. 1.1.
    \71\ CSRIC advises that 911 Authorities should understand 
historical cost recovery models for rural carriers and remain 
flexible to accommodate any economic challenges caused by the 
migration to NG911. Id. sec. 1.1.
    \72\ Id. sec. 1.1 (``Small carriers need to evaluate the 
interconnection options to the NG9-1-1 ESInet based upon 
negotiations with the NG9-1-1 System Service Provider (SSP). They 
may interconnect with native IP or via gateways based upon their own 
network transition plans.'').
    \73\ Id. sec. 5.2.2 (``[A] `pure' or `end-state' NG9-1-1 
implementation assumes OSPs have changed the means by which they 
deliver 9-1-1 calls, however it is not realistic or expected that 
all small carrier OSPs will change at the same time. Therefore, the 
model is complicated by mechanisms to `transition' from legacy 
methods to NG9-1-1 methods. The LNG is required until all OSPs 
deliver location information with their 9-1-1 call setup messages 
(location-by-value) or provide location databases that may be 
queried (location-by-reference).'').
    \74\ See id. secs. 1.1, 3.2.
---------------------------------------------------------------------------

    One of CSRIC's chief recommendations was for the Commission to 
``explore opportunities to resolve [the] cost recover[y] debate,'' 
referring to disputes between carriers and 911 Authorities over how to 
fairly allocate the costs of NG911 networks.\75\ CSRIC suggested that 
the Commission update its King County decision in order to resolve 
ongoing uncertainty about cost responsibilities in the NG911 
environment.\76\ CSRIC also suggested a three-stage structure for the 
transition to NG911, ranging from current legacy 911 systems; through a 
``transitionary phase'' in which carriers may not yet

[[Page 78072]]

originate 911 traffic in IP but are able to interconnect with a 911 
Authority's ESInet and deliver IP-based traffic via IP translation; and 
an ``End State . . . where the small carrier has deployed an IP-based 
network.'' \77\ In CSRIC's transitionary phase, the originating service 
provider would deliver 911 calls in IP via one of two options--either 
(1) by providing an LNG itself and converting its TDM signaling to SIP 
before interconnecting with the ESInet using native SIP and converting 
the legacy data access protocols (e.g. E2) to those used by the ESInet, 
or (2) by using legacy signaling (e.g., TDM) and data access protocols 
(e.g., E2) to interconnect with the ESInet at an LNG provided by the 
ESInet vendor.\78\ CSRIC also suggested that smaller carriers with 
fewer resources may need a longer timeline to transition to NG911, and 
it stressed the importance of coordination between carriers and 911 
Authorities.\79\ Overall, the CSRIC NG911 Transition Report called on 
the FCC to provide structure and certainty to the NG911 transition via 
rulemaking while maintaining some flexibility and accounting for 
smaller carriers' more-limited resources.

C. Recent Regulatory Changes

    NASNA Petition. In October 2021, NASNA filed a petition asking the 
Commission to initiate a rulemaking or notice of inquiry to facilitate 
the transition to NG911 (NASNA Petition).\80\ Specifically, NASNA asked 
the Commission to assert authority over the delivery of 911 
communications by OSPs to ESInets and to amend the Commission's rules 
as needed to advance the transition to NG911.\81\ As part of its 
petition, NASNA urged the Commission to set a default cost demarcation 
point in the NG911 environment analogous to its King County ruling in 
the E911 environment.\82\ NASNA also asked the Commission to set 
deadlines for OSPs to begin delivering 911 traffic in NG911 format when 
the relevant state or local 911 Authority achieves NG911 readiness, and 
to establish a registry through which 911 authorities would notify OSPs 
of their NG911 readiness status.\83\ The Public Safety and Homeland 
Security Bureau (PSHSB or Bureau) placed the Petition on public notice 
in December 2021, and received twenty-two comments, eight replies, and 
seven ex partes.\84\

    Wireless Location-Based Routing. In December 2022, the Commission 
issued the Location-Based Routing Notice proposing to require CMRS and 
covered text providers to implement location-based routing for 911 
calls and texts nationwide.\85\ As part of that proceeding, the 
Commission sought comment on aspects of the NG911 transition raised by 
the NASNA Petition as they applied to CMRS and covered text providers. 
Specifically, the Commission proposed to require CMRS and covered text 
providers to deliver 911 calls, texts, and associated routing 
information in IP format upon request of 911 Authorities that have 
established the capability to accept NG911-compatible IP-based 911 
communications.\86\ In addition, the Commission proposed to establish 
time frames for CMRS and covered text providers to deliver IP-based 911 
traffic.\87\ Further, the Commission sought comment on whether to make 
available a registry or database that would allow state and local 911 
authorities to notify CMRS and covered text providers of the 911 
authorities' readiness to accept IP-based communications.\88\ The 
Commission noted that these proposals, if adopted, would effectively 
implement a key element of NASNA's petition with respect to transition 
to NG911 for wireless 911 calls and texts, which represent an estimated 
80 percent of 911 traffic in many areas.\89\

    NG911 Notice Proposed Framework. In June 2023, the Commission 
issued the NG911 Notice seeking to establish a framework that would 
expedite the nation's transition to NG911 by proposing comprehensive 
requirements that would apply to wireline, CMRS, interconnected VoIP, 
and internet-based TRS providers.\90\ First, the Commission proposed to 
require wireline, interconnected VoIP, and internet-based TRS providers 
to complete all translation and routing to deliver 911 calls, including 
associated location information, in the requested IP-based format to an 
ESInet or other designated point(s) that allow emergency calls to be 
answered upon request of 911 authorities who have certified the 
capability to accept IP-based 911 communications.\91\ Second, as state 
and local 911 authorities transition to IP-based networks, the 
Commission proposed to require wireline, interconnected VoIP, CMRS, and 
internet-based TRS providers to transmit all 911 calls to destination 
point(s) designated by a 911 Authority.\92\ Third, the Commission 
proposed that in the absence of agreements by states or localities on 
alternative cost recovery mechanisms, wireline, interconnected VoIP, 
CMRS, and internet-based TRS providers must cover the costs of 
transmitting 911 calls to the point(s) designated by a 911 Authority, 
including any costs associated with completing the translation and 
routing necessary to deliver such calls and associated location 
information to the designated destination point(s) in the requested IP-
based format.\93\

authorities who have certified the capability to accept IP-based 911 
communications.'' Id.
    \93\ NG911 Notice, 38 FCC Rcd at 6205-06, para. 2. Under this 
proposal, the Commission noted that ``states and localities would 
remain free to establish alternative cost allocation arrangements

providers would be presumptively responsible for the costs 
associated with delivering traffic to the destination point(s) 
identified by the appropriate 911 authority.'' Id.
---------------------------------------------------------------------------

    In the NG911 Notice, the Commission explained that it sought to 
create a consistent framework for ensuring that all originating service 
providers take the necessary steps to implement the transition to NG911 
in coordination with 911 Authorities.\94\ In addition, the Commission 
sought to align the NG911 transition rules for wireline,

[[Page 78073]]

interconnected VoIP, and internet-based TRS providers with similar 
requirements that the Commission had proposed for CMRS and covered text 
providers in the LBR Notice, thereby promoting consistency across 
service platforms.\95\ The Commission also explained that the 
demarcation point and cost allocation proposals sought to address what 
NASNA described in its Petition as ``the critical component, and 
biggest regulatory roadblock, to transitioning to NG911 services.''

III. Discussion

    In this document and the Order, we require OSPs to support the 
NG911 transition. In the sections below and in the Order, we explain 
the basis for adopting NG911 transition rules, including the 
significant and potentially life-saving benefits that NG911 affords, 
and we set forth the scope and extent of our NG911 requirements. We 
also find that the deadlines adopted are achievable and technically 
feasible for OSPs.

A. The Need for Rules To Facilitate the NG911 Transition

    In the NG911 Notice and LBR Notice, the Commission proposed to 
expedite the nationwide transition to NG911 by adopting certain 
requirements that would apply to wireline, CMRS, covered text, 
interconnected VoIP, covered text providers, and internet-based TRS 
providers.\101\ Together, our proposals were intended not only to 
expedite this vital transition, but also to help ensure that the 
nation's 911 system functions effectively and utilizes advanced 
capabilities.\102\ In addition, the proposed rules in the NG911 Notice 
responded to the petition from NASNA, the organization that represents 
state 911 administrators, urging the Commission to adopt rules to 
facilitate the transition to NG911.\103\

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

    As the Commission noted in the NG911 Notice, to achieve the 
transition to NG911, state and local 911 authorities must implement IP-
based technologies and applications that will provide all of the 
functions of the legacy E911 system as well as new capabilities.\104\ 
NG911 relies on IP-based architecture to provide an expanded array of 
emergency communications services that encompasses both the core 
functionalities of legacy E911 and additional functionalities that take 
advantage of the enhanced capabilities of IP-based devices and 
networks.\105\ The transition to NG911 involves fundamental changes in 
the technology that 911 Authorities use to receive and process 911 
traffic, and it requires equally fundamental changes in the way OSPs 
deliver 911 traffic to PSAPs.\106\ The benefits that result from the 
transition to NG911 include improvements to 911 network reliability and 
resilience,\107\ improvements to interoperability between PSAPs, and 
location information that is available to PSAPs more quickly. As the 
Commission observed in the NG911 Notice, in its end state, NG911 will 
also support the transmission of text, photos, video, and data.\108\

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

    Most states have already made significant commitments to 
implementing NG911.\109\ Thirty-seven states and jurisdictions reported 
to the FCC in 2023 that they had ESInets operating in 2022.\110\ 
Despite investments in these new capabilities, however, some states 
report experiencing delays in OSPs connecting to their ESInets.\111\ 
Disputes with OSPs include issues of both cost allocation and the 
points to which the OSPs will deliver 911 traffic.\112\ In addition, 
some commenters contend that some OSPs have financial incentives to 
delay transitioning from legacy 911 to NG911, resulting in protracted 
disputes and mounting costs for 911 Authorities, and

[[Page 78074]]

further contributing to delays.\113\ As a result of these delays, 911 
Authorities incur prolonged and compounded costs because they must 
maintain both legacy and IP networks during the transition.\114\ 
Managing 911 traffic on both legacy and IP networks may also result in 
increased vulnerability and risk of 911 outages.\115\

Comments at 2). Specifically, the introduction of IP based elements 
requires dedicated monitoring and security measures separate from 
legacy systems, and the continued presence of legacy components of 
911 networks presents a risk of outages. For example, as noted by 
NASNA, the 911 Authority for the State of California tracks 
reliability and availability of the legacy 911 system and their 
statistics indicate an increase in the rate of downtime. ``In 2017 
the average number of minutes of outage was 17,000 minutes per 
month, but in 2022 the average increased to over 59,000 outage 
minutes per month.'' National Association of State 911 
Administrators (NASNA) LBR Notice Comments at 7-8 (rec. Feb. 16, 
2023) (NASNA LBR Notice Comments). This decrease in the reliability 
of legacy systems will best be offset when NG911 is fully 
implemented.
---------------------------------------------------------------------------

    Adopting rules in this proceeding is necessary to advance the 
critical transition to NG911, with its vital public safety benefits for 
the entire American public. Currently, as 911 Authorities deploy NG911 
infrastructure, there are no rules at the federal level describing what 
OSPs must do to support the transition. The lack of rules creates 
uncertainty for 911 stakeholders and increases delays in the 
transition. In addition, the increased costs incurred to support both 
911 and NG911 systems concurrently while the transition to NG911 is 
delayed reduce the limited amount of funding actually available to 
implement NG911 itself, further stalling the eventual transition to 
lifesaving NG911 technology across the country. The magnitude of delays 
and costs in the national transition to NG911 to date demonstrates the 
necessity and importance of the Commission taking action to establish a 
regulatory framework for the orderly and efficient implementation of 
NG911. In addition, we believe that promulgating a consistent 
regulatory approach to 911 for all OSPs reflects the reality that 
distinctions between OSP types are becoming less relevant as 
technologies converge and advance.\116\ This ``all platforms'' approach 
promotes accountability, transparency, and certainty.

    Numerous commenters on the NG911 Notice have voiced support for the 
Commission's goals in this rulemaking and have acknowledged the need 
for rules to facilitate the transition to NG911, although some have 
advocated for changes to the proposed rules.\117\ For example, NASNA 
says it is ``grateful'' to the Commission for its ``forward-thinking 
action in facilitating NG911,'' says ``[t]his rulemaking will be 
instrumental'' in moving NG911 forward, and ``urges timely 
implementation of effective rules to make NG911 a reality nationwide.'' 
The Maine PUC ``applauds the FCC for undertaking this rulemaking to 
expedite the much-needed transition to NG911.'' \118\ The Pennsylvania 
Emergency Management Agency notes that Pennsylvania's ability to 
successfully and completely implement NG911 service and retire legacy 
E911 technologies is hampered by the current lack of rules clarifying 
roles and responsibilities among stakeholders, and that a regulatory 
framework is needed.\119\ Similarly, Communications Equality Advocates 
(CEA) ``[a]pplauds'' the Commission's efforts to pave the way for full 
migration to NG911.\120\ NENA supports the Commission's NG911 
rulemaking proceeding and ``commends'' the Commission for initiating a 
proceeding ``to build a framework to make NG9-1-1 in our nation a 
reality.'' \121\ APCO indicates support of the Commission adopting 
NG911 rules, noting the Commission's proposals ``have the potential to 
accelerate the transition'' to NG911.\122\

[[Page 78075]]

Commenter iCERT notes its ``strong support for accelerating the 
implementation of NG911 across the country,'' urges the FCC ``to 
establish a clear regulatory framework,'' and urges the FCC ``to act 
promptly in this proceeding'' due to the ``urgent need to implement 
NG911 throughout the nation.'' \123\ Comtech expresses support for the 
Commission's proposed NG911 rules and notes ``the urgent need for swift 
adoption of these rules to help mitigate NG911 deployment delays.'' 
\124\ Other commenters note the benefits of transitioning to NG911 and 
support Commission action to facilitate that transition.\125\ Only one 
commenter appears to be opposed to the Commission adopting rules in 
some form to facilitate the transition to NG911.\126\

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

    Therefore, based on the foregoing and the record as a whole, we 
conclude that there is a need for the Commission to establish rules to 
facilitate the NG911 transition. We believe the rules provide a 
regulatory framework that will assist in expediting the critical 
transition to NG911 nationwide, which will serve to greatly promote 
public safety in the years to come.

B. Definitions of Key Terms

    In this section, we discuss and adopt definitions for certain key 
terms, such as ``Next Generation 911 (NG911),'' ``commonly accepted 
standards,'' ``Emergency Services internet Protocol Network (ESInet),'' 
and other terms. The definitions we adopt for additional key terms, 
such as ``911 Traffic,'' ``NG911 Delivery Point,'' ``Session Initiation 
Protocol (SIP),'' ``Functional Element,'' ``Location Validation 
Function (LVF),'' and ``Location Information Server (LIS)'' are 
discussed in subsequent sections of this document and the Order.
    Next Generation 911 (NG911). In the NG911 Notice, the Commission 
sought comment on defining the term ``Next Generation 911.'' \127\ As 
reflected in relevant proposed legislation and the comments of parties 
in the NG911 and LBR proceedings, stakeholders have varying views on 
how, or even whether, to define Next Generation 911 in the Commission's 
rules. In the NG911 Notice, the Commission noted that there are 
multiple definitions of ``NG911'' in proposed federal legislation and a 
definition of ``Next Generation 9-1-1 services'' in federal law.\128\ 
The Spectrum Auction Reauthorization Act of 2023 (H.R. 3565), a bill 
introduced in May 2023, proposed the following definition of ``Next 
Generation 9-1-1'':
---------------------------------------------------------------------------

    \127\ See, e.g., NG911 Notice, 38 FCC Rcd at 6229-30, para. 51.
    \128\ NG911 Notice, 38 FCC Rcd at 6229-30, para. 51.

    [A]n internet Protocol-based system that--(A) ensures 
interoperability; (B) is secure; (C) employs commonly accepted 
standards; (D) enables emergency communications centers to receive, 
process, and analyze all types of 9-1-1 requests for emergency 
assistance; (E) acquires and integrates additional information 
useful to handling 9-1-1 requests for emergency assistance; and (F) 
supports sharing information related to 9-1-1 requests for emergency 
assistance among emergency communications centers and emergency 
response providers.\129\

    Several other pieces of recent proposed federal legislation have 
used the same or a very similar definition of NG911.\130\
---------------------------------------------------------------------------

    \130\ The same definition of NG911 used in H.R. 3565 was also 
used in a March 2023 House bill, H.R. 1784 (the Next Generation 9-1-
1 Act of 2023), and in a 2022 House bill, H.R. 7624 (the Spectrum 
Innovation Act of 2022). See H.R. 1784, 118th Cong. sec. 159(d)(12) 
(2023), <a href="https://www.congress.gov/bill/118th-congress/house-bill/1784/text">https://www.congress.gov/bill/118th-congress/house-bill/1784/text</a>; H.R. 7624, 117th Cong. sec. 159(d)(11) (2022), <a href="https://www.congress.gov/bill/117th-congress/house-bill/7624/text">https://www.congress.gov/bill/117th-congress/house-bill/7624/text</a>. In 
addition, a bill introduced in the Senate in July 2023, S. 2712, 
proposes a similar definition of NG911: ``NEXT GENERATION 9-1-1.--
The term `Next Generation 9-1-1' means an interoperable, secure, 
internet Protocol-based system that--(A) employs commonly accepted 
standards; (B) enables emergency communications centers to receive, 
process, and analyze all types of 9-1-1 requests for emergency 
assistance; (C) acquires and integrates additional information 
useful to handling 9-1-1 requests for emergency assistance; and (D) 
supports sharing information related to 9-1-1 requests for emergency 
assistance among emergency communications centers and emergency 
response providers.'' S. 2712, 118th Cong. sec. 4(9) (2023), <a href="https://www.congress.gov/bill/118th-congress/senate-bill/2712/text?s=1&r=72">https://www.congress.gov/bill/118th-congress/senate-bill/2712/text?s=1&r=72</a>. Congress used a somewhat different definition of 
NG911 in the Next Generation 9-1-1 Advancement Act of 2012, for 
purposes of administration of Federal 911 implementation grants. 
That earlier statute provides that ``Next Generation 9-1-1 
services'' means ``an IP-based system comprised of hardware, 
software, data, and operational policies and procedures that--(A) 
provides standardized interfaces from emergency call and message 
services to support emergency communications; (B) processes all 
types of emergency calls, including voice, data, and multimedia 
information; (C) acquires and integrates additional emergency call 
data useful to call routing and handling; (D) delivers the emergency 
calls, messages, and data to the appropriate public safety answering 
point and other appropriate emergency entities; (E) supports data or 
video communications needs for coordinated incident response and 
management; and (F) provides broadband service to public safety 
answering points or other first responder entities.'' 47 U.S.C. 
942(e)(5).

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

[[Page 78076]]

    Some commenters on the LBR Notice argued that the Commission should 
adopt a definition of NG911.\131\ For example, APCO urged the 
Commission to adopt the definition of NG911 ``as defined by the public 
safety community with support from a variety of stakeholders'' that 
appeared in legislation passed by the House of Representatives in 2022 
but that was not enacted into law.\132\ By contrast, NENA urged the 
Commission to ``be cautious in adopting formal definitions [of terms 
such as NG911] . . . without full industry-wide support and without 
considering all potential consequences of such definitions.'' \133\ 
NENA also asked the Commission to consider using the term ``i3 
compatible'' or some other mutually agreed upon terminology rather than 
``IP-enabled'' to describe standards-based NG911.\134\

    \132\ APCO LBR Notice Comments, at 5 (rec. Feb. 16, 2023). In 
its LBR comments, APCO urged the Commission to define NG911 as ``an

(C) employs commonly accepted standards; (D) enables emergency

    In the NG911 Notice, the Commission sought comment on whether it 
should adopt one of these definitions or incorporate elements of these 
or other definitions of NG911 into our rules.\135\ The Commission asked

proposed NG911 rules and, if so, sought input on crafting a definition 
that would be technologically neutral.\136\ The Commission noted that 
recent proposed legislative definitions include qualitative descriptors 
of NG911 systems, such as security, interoperability, and use of 
commonly accepted standards, as well as specific technical 
capabilities.\137\ The Commission asked if it should include any or all 
of these elements in a definition of NG911 adopted by the Commission, 
and whether the definitions discussed encompass current NG911 networks 
and technologies as well as possible future NG911 technologies.\138\

    In comments on the NG911 Notice, APCO contends that a definition of 
NG911 is necessary. APCO again urges the Commission to adopt the same 
definition of NG911 proposed in the Spectrum Auction Reauthorization 
Act of 2023 (H.R. 3565), calling this a ``comprehensive definition . . 
. crafted by the public safety community,'' and stating that adopting 
this definition is important for aligning the rules with public 
safety's needs and the Commission's objectives.\139\ Similarly, NASNA 
indicates a definition of NG911 is needed and advocates adopting the 
NG911 definition used in H.R. 3565.\140\ Mission Critical Partners also 
believes that a definition of NG911 is needed, stating that, to speed 
up the process of migrating to NG911, ``it would be best to have the 
Commission define, for purposes of the rulemaking, what NG911 means.'' 
However, Mission Critical Partners states that ``NG911 has been defined 
differently by many groups,'' and advocates for a different and more 
detailed definition of NG911 than that recommended by APCO and 
NASNA.\141\ NENA notes that a definition of NG911 and other terms ``can 
provide stakeholders with clarity'' as the transition to NG911 
progresses, and recommends that an NG911 definition be standards based. 
Nevertheless, NENA again cautions the Commission only to adopt formal 
definitions for terms with public and private 911 industry-wide 
support.\142\

Notice Reply at 2-3 (rec. Sept. 8, 2023) (APCO NG911 Notice Reply) 
(noting that commenters offer a variety of opinions on how to define 
NG911, which ``underscores the need for the Commission to provide a 
common understanding of the public safety community's goals and 
expectations for NG9-1-1''; stating that providing a comprehensive 
NG911 definition is necessary to achieve the Commission's objectives 
and that adopting ``the public safety community's comprehensive 
definition'' of NG911 will provide ``a north star''). APCO also 
advocates that adopting this specific NG911 definition ``is a basic 
step to ensure that, should Congress pass NG9-1-1 funding 
legislation, the Commission's rules facilitating NG9-1-1 will align 
with the $15 billion grant program for communities across the 
country to deploy NG9-1-1.'' APCO NG911 Notice Comments at 3. We 
note, however, that should Congress pass NG911 funding legislation 
in the future, Congress will not necessarily use this particular 
definition of NG911 and may instead adopt a different definition.
    \140\ NASNA NG911 Notice Comments at 4-5 (NASNA believes the 
Commission's proposed rule should reflect the following NG911 
definition: ``A tiered system consisting of multiple IP-based 
networks that: (A) ensures interoperability; (B) is secure; (C) 
employs commonly accepted standards; (D) enables emergency 
communications centers and Public Safety Answering Points to 
receive, process, and analyze all types of 911 requests for 
emergency assistance; (E) acquires and integrates additional 
information useful to handling 911 requests for emergency 
assistance; and (F) supports sharing information related to 911 
requests for emergency assistance among emergency communications 
centers and emergency response providers.''). NASNA explains that it 
believes the standards suggested by APCO and the standards suggested 
by NENA ``both have applicability as it relates to the proposed 
rules,'' but ``we believe it is important to acknowledge that an 
end-to-end NG911 `system' consists of multiple networks and systems 
which are subject to different, but complementary interoperable 
standards.'' NASNA further explains that, ``[w]ith this perspective, 
NASNA offers a revision to the Next Generation 911 definition as it 
relates to the rules of this NPRM which recognizes the various 
networks at work.'' NASNA NG911 Notice Comments at 4-5.
    \141\ Mission Critical Partners suggests, ``[f]or example,'' the 
following definition: ``Next Generation 911, commonly referred to as 
NG911, is a system of interconnected systems that delivers and 
processes calls for help from the public and delivers the media to 
the appropriate [Emergency Communications Center]/PSAP. NG911 must 
include at a minimum: An IP-based transport ability that 
interconnects the system components, ECCs/PSAPs, and disparate NG911 
systems. This should be a robust, properly sized, resilient 
network.[;] Ability to receive SIP sessions to include all types of 
media (voice, video, picture, Real-Time Text [RTT], etc.). While the 
Commission could limit this requirement to specific types of media, 
that would require future rule changes.[;] Ability to receive and 
process call-routing and location data from the geolocation SIP 
header.[;] Ability to process routing and location data by value and 
by reference.[;] Ability to have authoritative geographic 
information system (GIS) information, including address points, 
street centerlines, and boundary polygons, needed to process calls 
and sessions.[;] Ability to deliver calls and sessions to ECCs/
PSAPs.[;] Ability to bridge additional users into calls in progress, 
e.g., language services, other ECCs/PSAPs.[;] Ability to apply rules 
to the routing of calls and sessions using all available data 
provided in the SIP messaging, including routing and location data 
that is dereferenced.[;] Ability to provide cybersecurity functions 
at the edges of all interconnected networks and throughout the inner 
workings of each NGCS.[;] Ability to transfer calls and sessions 
between ECCs/PSAPs on the network and to other NG911 systems without 
the loss of location data.[;] Ability to log, and report on, call 
data and associated network, service, and system activity.'' Id. at

own definition of NG911, but acknowledges that a variety of other 
definitions have been proposed and that the NENA definition ``is not 
sufficient for the specific scope of the Commission's proceeding 
without modification,'' including adding reference ``an i3-centric 
architecture.'' Id.
---------------------------------------------------------------------------

    Commenters also express differing views on whether a codified 
definition of NG911 should reference the NENA i3 standard or any 
specific technical standard. To ensure compatibility and

[[Page 78077]]

interoperability of NG911 systems, NENA argues that any definition of 
NG911 should reference ``an i3-centric architecture.'' \143\ Colorado 
PUC agrees that the Commission should consider including language 
regarding ``i3 standard compatibility'' in the NG911 definition, 
stating that ``[t]he vast majority, if not all'' implementations of 
NG911 technology across the country have the goal of deploying i3-based 
NG911 systems.\144\ In contrast, APCO opposes incorporating i3 or any 
other specific NG911 standard into the Commission's rules, noting that 
there are alternative potential standards, that the telecommunications 
ecosystem and technology continue to evolve, and that Emergency 
Communications Centers (ECCs) should have flexibility to pursue their 
preferred approaches with a ``technology-neutral approach'' that 
ensures ``ECCs can continually benefit from ongoing innovation.'' \145\ 
APCO urges that the Commission must avoid rules or assumptions that 
might ``lock ECCs into a particular approach to implementing NG9-1-1'' 
and should not adopt rules ``that bake in specific architectures for 
NG9-1-1.'' APCO states that this is why the public safety community's 
``comprehensive definition of NG9-1-1 [i.e., the definition in H.R. 
3565, H.R. 1784, and H.R. 7624] references the use of `commonly 
accepted standards' rather than identify[ing] a particular standard for 
NG9-1-1.'' \146\ Mission Critical Partners also advocates for a 
``technology-neutral definition'' of NG911 ``to reduce any ambiguity by 
providers or 911 authorities regarding compliance with the proposed 
NG911 rulemaking.'' \147\

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

    We find that adopting a definition of NG911 will facilitate 
compliance with the NG911 rules, as it will help promote clarity and 
certainty about the Commission's NG911 requirements. Accordingly, we 
adopt the definition of NG911 used in the Spectrum Auction 
Reauthorization Act of 2023 (H.R. 3565), a definition that is supported 
by multiple stakeholders in the public safety community and that has 
been used in several recent pieces of proposed Federal legislation. 
Although not all commenters to this proceeding support this specific 
definition, we believe that it comes closest to reflecting a broad 
consensus as to the essential elements that should be included in a 
definition of NG911. In particular, the definition will advance our 
goal of a technology-neutral approach to implementation of NG911, and 
it contains the important requirements that an NG911 system ensure 
interoperability, be secure, and employ commonly accepted standards.
    We decline to reference any specific standard or set of standards 
as part of the codified definition of NG911. Although NENA and Colorado 
PUC advocate for including a reference to the i3 standard in the rules, 
we conclude that the better approach is to adopt a technology-neutral 
definition that avoids referencing any specific standard. As discussed 
below, we believe commenters' concerns that NG911 development be 
standards-based are fully addressed by including ``commonly accepted 
standards'' as an element of our NG911 definition.\148\
---------------------------------------------------------------------------

    \148\ We agree with commenters that the i3 standard meets the 
definition of a ``commonly accepted standard'' under the definition 
in this document and the Order.
---------------------------------------------------------------------------

    We have also considered, but decline to adopt, the more detailed 
NG911 definition suggested by Mission Critical Partners. Mission 
Critical Partners' proposed NG911 definition identifies many specific 
operational and technical functions, such as the ability to ``bridge 
additional users into calls in progress;'' ``provide cybersecurity 
functions at the edges of all interconnected networks and throughout 
the inner workings of each NGCS,'' ``transfer calls and sessions 
between ECCs/PSAPs on the network and to other NG911 systems without 
the loss of location data,'' and ``log, and report on, call data and 
associated network, service, and system activity.'' While we anticipate 
that many NG911 networks will support these capabilities, incorporating 
this level of detail into the codified definition of NG911 appears 
unnecessary and could cause confusion to the extent that it goes beyond 
the level of detail in the draft legislative definition supported by 
most commenters.\149\
---------------------------------------------------------------------------

    \149\ We note, however, that some of the elements of Mission 
Critical Partners' proposed ``NG911'' definition are already 
included in the ``NG911'' definition. For example, Mission Critical 
Partners' element of ``[a]n IP-based transport ability that 
interconnects the system components, ECCs/PSAPs, and disparate NG911 
systems'' appears to match our final definition's requirement of 
``ensures interoperability,'' and its required element of 
``[a]bility to provide cybersecurity functions at the edges of all 
interconnected networks and throughout the inner workings of each 
NGCS'' appears to match our final definition's requirement of ``is 
secure.'' Mission Critical Partners NG911 Notice Comments at 10-11.
---------------------------------------------------------------------------

    The definition of NG911 addresses other concerns raised by 
commenters on the NG911 Notice. In the NG911 Notice, the Commission 
sought comment on how to ensure that its proposed rules would support 
interoperability in the NG911 environment.\150\ Commenters confirm the 
importance of interoperability in NG911 to enable the efficient 
transfer of emergency calls, texts, and data between ESInets, PSAPs, 
and first responders.\151\ In addition, commenters note that the 
uniform use of commonly accepted standards by OSPs and NG911 vendors is 
a necessary prerequisite to interoperability,\152\ although it is not 
enough by itself to achieve interoperability.\153\ Consistent with 
commenters' views, the definition of NG911 in this document and the

[[Page 78078]]

Order therefore specifies that NG911 systems shall ``ensure 
interoperability.'' \154\

capable of processing `all types' of requests.'' CEA states that ``[w]e 
read this requirement as mandating that NG911 standards support 
accessible technologies.'' We agree with CEA's reading and find that 
adopting the same language used in H.R. 3565 is sufficient to 
incorporate the accessibility component into the NG911 definition.

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

    Commonly Accepted Standards. The NG911 definition specifies that 
NG911 systems and technology must be based on ``commonly accepted 
standards.'' In the NG911 Notice, we discussed the concept of commonly 
accepted standards but did not propose a specific definition of that 
term.\157\

proposed by commenters or discussed in the NG911 Notice included the 
term ``commonly accepted standards.'' See, e.g., NG911 Notice, 38 
FCC Rcd 6229-30, para. 51 & n.166; NASNA NG911 Notice Comments at 4-

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

    Commenters generally support including a definition of ``commonly 
accepted standards'' in the rules. The proposed legislation in H.R. 
3565 provides a definition of ``commonly accepted standards.'' \158\ 
NENA offers a similar definition that ``very closely aligns with the 
definitions as promulgated in multiple NG9-1-1 funding bills as 
introduced in Congress.'' \159\ We find that requiring that the 
commonly accepted standards be developed and approved by an accredited 
standards development organization will help ensure that there is a 
minimum threshold for ensuring the integrity and validity of such 
standards, as technology continues to evolve over time. Accordingly, we 
adopt the following definition of ``commonly accepted standards'':
---------------------------------------------------------------------------

    \158\ H.R. 3565 states: ``The term `commonly accepted standards' 
means the technical standards followed by the communications 
industry for network, device, and internet Protocol connectivity 
that--(A) enable interoperability; and (B) are--(i) developed and 
approved by a standards development organization that is accredited 
by an American standards body (such as the American National 
Standards Institute) or an equivalent international standards body 
in a process--(I) that is open to the public, including open for 
participation by any person; and (II) provides for a conflict 
resolution process; (ii) subject to an open comment and input 
process before being finalized by the standards development 
organization; (iii) consensus-based; and (iv) made publicly 
available once approved.''
    \159\ NENA NG911 Notice Reply at 12-13 & nn.39-40 (rec. Sept. 6, 
2023). NENA's proposed definition requires that the technical 
standards be ``developed and approved by a recognized standards 
development organization, that may be accredited by a United States 
or international standards accreditation body.''

    The technical standards followed by the communications industry 
for network, device, and internet Protocol connectivity that--(1) 
enable interoperability; and (2) are--(i) developed and approved by 
a standards development organization that is accredited by a United 
States standards body (such as the American National Standards 
Institute) or an equivalent international standards body in a 
process that--(A) is open to the public, including open for 
participation by any person; and (B) provides for a conflict 
resolution process; (ii) subject to an open comment and input 
process before being finalized by the standards development 
organization; (iii) consensus-based; and (iv) made publicly 
---------------------------------------------------------------------------
available once approved.

    This definition tracks the definition of ``commonly accepted 
standards'' set forth in H.R. 3565, with minor non-substantive 
revisions.\160\
---------------------------------------------------------------------------

    \160\ The definition we adopt refers to accreditation by a 
``United States standards body'' rather than an ``American standards 
body.'' In addition, we have moved the word ``that'' to precede the 
(2)(i)(A) provision, so that it modifies both subsections that 
follow. Finally, we have made non-substantive changes to the 
introductory wording and numbering of the definition for consistency 
with adjacent rule provisions.
---------------------------------------------------------------------------

    As noted above, this definition of ``commonly accepted standards'' 
does not specify a particular standard or set of standards to which 911 
Authorities or networks must adhere. This approach gives parties 
flexibility to implement changes or improvements as more advanced 
technologies become available and allows industry standards to evolve 
without the need for rule changes. Equally important, our approach 
discourages the use of ``proprietary . . . standards,'' \161\ which do 
not meet the definition of ``commonly accepted standards'' as they (1) 
would not enable interoperability; and (2) would not be developed and 
approved by a standards development organization accredited by a United 
States standards body or equivalent international standards body, 
subject to an open, consensus-based comment and input process prior to 
finalization, or made publicly available once approved.

by-vendor.'').
---------------------------------------------------------------------------

    We also emphasize that the NENA i3 standard qualifies as a 
``commonly accepted standard'' under the definition in this document 
and the Order. \162\ As numerous commenters indicate, the i3 standard 
is the prevailing standard adopted by all NG911 systems currently being 
deployed in the U.S. (and in Canada and Europe) is the NENA i3 
standard.\163\ The i3 standard has been approved by the American 
National Standards Institute (ANSI),\164\ following an open comment and 
input process, and was made publicly available once approved.\165\ In 
addition, work is ongoing to improve and augment the i3 standard as the 
NG911 transition proceeds.\166\ While we do not specifically reference 
the i3 standard in our rules, as some commenters advocate,\167\ we 
regard the widespread

[[Page 78079]]

adoption of i3 as a positive trend that will help ensure that the 
development of NG911 is in accordance with ``commonly accepted 
standards'' as defined in our rules. At the same time, our rules 
provide flexibility that will ``help promote a technology-neutral 
approach that ensures that ECCs can continually benefit from ongoing 
innovation.''

    911 Authority. In the NG911 Notice, the Commission proposed to

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

    The South Carolina Revenue and Fiscal Affairs Office (South 
Carolina RFA) agrees that the NG911 Notice's proposed definition 
``sufficiently encompasses the roles and responsibilities of the 911 
Authority for the State.'' Other commenters, however, propose to modify 
the definition. NASNA states that the definition should reference 911 
Authorities' broader responsibilities for coordinating the deployment 
of the ESInet and its data inputs and proposes to define ``911 
authority'' as ``[t]he state, territorial, regional, Tribal, or local 
agency or entity with the authority and responsibility under applicable 
law to procure and administer an ESInet and NG911 core services on 
behalf of one or more PSAPs and to designate the point(s) to receive 
emergency calls.'' Commenter Brian Rosen similarly states that the 
Commission should define ``911 Authority'' as ``the entity contracting 
for the ESInet and the NGCS service.'' \170\ Colorado PUC notes that 
there may be 911 Authorities with concurrent jurisdiction over the same 
geographic area but ``having different roles and responsibilities'' 
over the 911 system and suggests including language indicating this 
possibility.\171\ We agree with these commenters and include a 
reference in our definition of ``911 Authority'' to the operation or 
administration 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.'' This definition better captures the 
range of responsibilities that 911 Authorities have and is broad enough 
to accommodate the possibility of overlapping authorities--for example, 
a state's public safety agencies and its public utility commission--
over various aspects of the state's 911 network(s).

a state may have a single state-level 911 authority, but each region 
may also have a local 911 authority, with the state and local 
authorities having different roles and responsibilities.'').
---------------------------------------------------------------------------

    We find that this modified definition of ``911 Authority'' will 
provide greater clarity and assist parties in complying with our rules. 
Accordingly, we adopt the following definition of ``911 Authority'':

    ``911 Authority'': 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.\172\
---------------------------------------------------------------------------

    \172\ The term ``NG911 Delivery Point'' is also defined in this 
rulemaking.

    Emergency Services internet Protocol Network (ESInet). In the NG911 
Notice, the Commission proposed to adopt a definition of ``Emergency 
Services internet Protocol Network (ESInet)'' that would define the 
term ``in reference to the protocol used on the network, the entities 
that manage the network, and the use of the network for purposes of 
emergency services communications.'' \173\ The Commission's proposed 
definition was ``[a]n internet Protocol (IP)-based network managed by 
public safety authorities and used for emergency services 
communications, including Next Generation 911.'' \174\

``Emergency Services internet Protocol Network (ESInet)'' as ``[a]n 
internet Protocol (IP)-based network used for emergency services 
communications, including Next Generation 911'').
---------------------------------------------------------------------------

    Mission Critical Partners generally supports this definition of 
ESInet but notes that the ESInet is ``simply a transport mechanism.'' 
\175\ NASNA proposes to define ESInet as: ``[t]he internet Protocol 
(IP)-based network tier of a Next Generation 911 system that exists 
between the points designated by the 911 authority and a PSAP, which is 
used for emergency services communications, including Next Generation 
911.'' NENA states that ``[w]ithin the confines of this proceeding,'' 
it concurs with NASNA's proposed definition for ESInet.\176\ Alaska 
Telecom notes that the Commission seeks comment on the definitions of 
both ``NG911'' and ``ESInet,'' and says that any definitions adopted 
should reference ``statewide, or at least regional, ESInet 
development,'' as doing so will ensure that deployment of NG911

(``Furthermore, deploying NG911 networks in coordination with an in-

providers to somehow deliver traffic to a demarcation point far

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

    We adopt a definition of ``ESInet'' similar to that proposed in the 
NG911 Notice, with slight revisions to add greater clarity and 
certainty to what constitutes an ESInet for purposes of these NG911 
rules. The modifications in this final definition are consistent with 
the criteria set forth by the Commission in the NG911 Notice, and also 
reflect wording that NASNA and NENA support and recommend in their 
proposed ``ESInet'' definition. The definition is as follows:

    Emergency Services internet Protocol Network (ESInet). An 
internet Protocol (IP)-

[[Page 78080]]

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.

    The adopted definition of ``ESInet'' reflects the three criteria 
that we proposed in the NG911 Notice for the definition of ``ESInet''--
the protocol used on the network, the entities that manage the network, 
and the use of the network for purposes of emergency services 
communications.\178\ In addition, while our proposed definition 
provided that the network must be managed by ``public safety 
authorities,'' the final definition adopted provides greater clarity by 
specifying that the network must be managed or operated by a ``911 
Authority or its agents or vendors,'' with ``911 Authority'' being a 
term specifically defined elsewhere in the rules.
---------------------------------------------------------------------------

    \178\ NG911 Notice, 38 FCC Rcd at 6230, para. 52.
---------------------------------------------------------------------------

    NASNA and NENA propose stating in the definition that the ESInet is 
the ``internet Protocol (IP)-based tier of a Next Generation 911 system 
that exists between the points designated by the 911 authority and a 
PSAP.'' While ESInets typically operate in the manner described by 
NASNA and NENA, we believe that ESInets should be defined functionally 
without reference to any particular ``tier'' or network configuration. 
Alaska Telecom recommends that the ``ESInet'' definition reference 
``statewide, or at least regional, ESInet development'' to ensure that 
NG911 networks are not deployed on a PSAP-by-PSAP, provider-by-provider 
basis. We find that it is not necessary to include specific wording on 
this issue. The ``ESInet'' definition is intended to be flexible and 
leaves the scale of ESInet deployment (e.g., local, state, or regional) 
to the discretion of stakeholders.
    Originating Service Providers. The NG911 Notice discussed wireline 
providers, rural wireline providers, and non-rural telecommunications 
wireline providers,\179\ but it did not propose specific definitions 
for ``Wireline Provider'' or ``Non-Rural Wireline Provider.'' 
Similarly, the NG911 Notice did not specifically propose to define the 
terms ``Nationwide CMRS Provider,'' ``Non-Nationwide CMRS Provider,'' 
and ``Rural Incumbent Local Exchange Carrier (RLEC).'' In addition, the 
Commission noted that it had previously defined the term ``Covered Text 
Provider'' at 47 CFR 9.10(q)(1),\180\ but did not specifically propose 
to adopt a definition of that term in this proceeding. However, in the 
NG911 Notice the Commission sought comment on whether there are ``any 
other terms that we should define for purposes of the cost allocation 
and IP-delivery rules.'' \181\ The terms ``Wireline Provider,'' ``Non-
Rural Wireline Provider,'' ``Covered Text Provider,'' ``Nationwide CMRS 
Provider,'' ``Non-Nationwide CMRS Provider,'' and ``Rural Incumbent 
Local Exchange Carrier (RLEC)'' are used in certain NG911 rules. We 
find that specifically defining these terms will ensure greater clarity 
and certainty, and will help parties to comply with our regulations. 
Accordingly, we incorporate and adopt the definitions for these terms 
that have previously been set forth in other existing statutes and 
regulations.

    The NG911 Notice and the LBR Notice did not specifically propose a 
defined term that would encompass all providers that would be 
specifically subject to NG911 rules. We define the term ``Originating 
Service Providers'' for purposes of this rulemaking and the new NG911 
rules as follows:

    Originating Service Providers. Providers 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.

    Other Definitions. Some commenters suggest that the Commission 
codify definitions of additional terms, such as ``Associated Location 
Information,'' \182\ ``IP-based format,'' \183\ and ``Phases of 
Readiness.'' \184\ We conclude that adopting formal definitions of 
these terms is unnecessary, but we note that some of the suggested 
additional terms are discussed and explained in other sections of this 
document and the Order.\185\ We believe that the formal definitions we 
adopt in this proceeding provide sufficient certainty, clarity, and 
guidance for stakeholders at this time.

technically more precise term than ``IP-based format'' and similar 
terms. In this document and in section III.C.2 of the Order, we

C. Service Providers' Obligation To Deliver 911 Traffic in IP Format 
Upon Request

1. Two-Phased Implementation of IP-Based Transmission Formats
a. Overview
    For the transition to NG911, we adopt rules that require OSPs to 
take steps in two phases to complete all translation and routing to 
deliver 911 traffic, including associated routing and location 
information, in the requested IP-based format. These requirements are 
intended to correspond to and complement the readiness phases for 911 
Authorities, such that once a 911 Authority is ready to receive NG911 
traffic in a specific IP format, the OSP will be required to deliver it 
in that format.
    In the LBR Notice, the Commission proposed to require CMRS and 
covered text providers to deliver 911 calls, texts, and associated 
location information in IP-based format to NG911-capable PSAPs that 
request it.\186\ The Commission reasoned that such a requirement would 
advance the transition to NG911 by helping address operational and 
routing issues for jurisdictions that have implemented NG911.\187\ The 
Commission also noted that the 2016 TFOPA Report concluded that a 
significant impediment to NG911 service was that originating service 
providers were not prepared to deliver 911 calls via IP technology with 
location information to NG911 service providers.\188\ The Commission 
reasoned that requiring OSPs to deliver IP-formatted calls and routing 
information to NG911-capable PSAPs would alleviate the burden on state 
and local

    In the NG911 Notice, the Commission proposed to require wireline, 
interconnected VoIP, and internet-based TRS providers to complete all 
translation necessary to deliver 911 calls, including associated 
location information, in the requested IP-based format to an ESInet or 
other designated point(s) that allow emergency calls to be answered 
upon request of 911 Authorities who have established the capability to 
accept NG911-compatible, IP-based 911 communications.\191\ The 
Commission reasoned that its proposal would help jurisdictions that are 
seeking to implement NG911 by alleviating the burden on 911 Authorities 
to maintain transitional gateways and other network elements to process 
and convert legacy calls \192\ and would complement its IP-delivery 
proposal in the LBR Notice.\193\ In the NG911 Notice, the Commission 
sought comment on achieving regulatory parity in its requirements for 
delivery of IP-based 911 calls by CMRS, wireline, interconnected VoIP, 
and internet-based TRS providers, and asked whether there were reasons 
to apply different requirements to 911 calls from different 
platforms.\194\ In addition, the Commission sought specific comment on 
how its proposal should extend to 911 calls that originate on non-IP 
wireline networks \195\ and how to extend its proposed requirement to 
internet-based TRS.\196\

requirements to deliver 911 communications in IP-based format to 
those we have proposed for CMRS and covered text providers.'').

    In both the LBR Notice and NG911 Notice, the Commission proposed to 
require OSPs to complete all NG911 transition steps in a single 
phase.\197\ In the NG911 Notice, the Commission also sought comment on 
whether to consider different or additional phases, including NASNA's 
proposal for three phases based on TFOPA's ``NG911 Readiness

    In response to the NG911 Notice, several commenters, including 
NASNA, USTelecom, Intrado, MSCI, iCERT, and the Colorado PUC, advocate 
for regulations that account for multiple phases in the transition to 
NG911.\200\ Several of these commenters indicate that a phased approach 
would better reflect the realities of the ongoing, typically phased, 
implementation of NG911 thus far. NASNA states that the implementation 
of NG911 is ``typically a multi-phase transition process'' and that 
``there is not just one phase of readiness.'' Intrado states that ``a 
phased-in approach . . . account[s] for, on the one hand, the 
significant difference between delivering IP-formatted traffic to the 
NG911 POI and delivering i3-formatted traffic and, on the other hand, 
differences in OSP type.'' iCERT states that ``FCC rules should 
recognize and accommodate various stages of NG911 implementation.'' 
MSCI argues that requiring immediate implementation of full NG911 
capabilities in a single phase would ``complicate, if not frustrate, 
the Commission's goal to more quickly transition TDM-based 
communications to IP-based communications.'' However, some commenters 
support implementation of the transition in a single phase,\201\ urge 
the Commission to seek further comment on phased approaches, or urge 
the Commission to create an industry task force to further study 
NG911.\202\

    We require OSPs to complete in two phases all translation and 
routing to deliver 911 traffic, including associated location 
information, in the requested IP-based format.\203\ In Phase 1, OSPs 
will be required to deliver 911 traffic in a basic SIP format, thereby 
implementing the fundamental IP translation or transport that is a 
prerequisite for the delivery of 911 traffic in SIP format that 
complies with commonly accepted standards. In Phase 2, OSPs will be 
required to deliver 911 traffic in SIP format that complies with NG911 
commonly accepted standards. This approach represents a division of the 
one phase approach proposed in the LBR Notice and NG911 Notice.
---------------------------------------------------------------------------

    \203\ Associated location information means the location 
information that OSPs are required to determine and transmit under 
current part 9 rules. We clarify that nothing in our rules is 
intended to change location determination requirements for OSPs, 
meaning the accuracy or reliability of the location information 
provided with 911 calls. See, e.g., 47 CFR 9.8 (indicating the 
dispatchable location requirement for wireline providers); 
9.10(i)(2)(i) (indicating horizontal dispatchable location 
requirements for CMRS providers); 9.10(i)(2)(ii) (indicating 
vertical dispatchable location requirements for CMRS providers); 
9.11(b)(4) (indicating dispatchable location requirements for 
interconnected VoIP providers); 9.14(d)(4) (indicating dispatchable 
location requirements for VRS and IP Relay providers); 9.14(e)(4) 
(indicating dispatchable location requirements for IP CTS 
providers).
---------------------------------------------------------------------------

    We adopt two phases for all OSPs--i.e., wireline providers, CMRS 
providers, covered text providers, interconnected VoIP providers, and 
internet-based TRS providers--to facilitate an ordered and synchronized 
transition to NG911, to better reflect the transition to NG911 as it 
currently is progressing, and to achieve regulatory parity in the 
requirements for the delivery of IP-based 911 calls across different 
platforms. We agree with Colorado PUC that ``every implementation of 
NG911 is being accomplished on a phased basis, so allowing for multiple 
iterations of requirements to be established is necessary.'' \204\ This 
approach recognizes that OSPs will need additional time to achieve 
delivery of 911 traffic using NG911 commonly accepted standards in 
Phase 2.
---------------------------------------------------------------------------

    \204\ Colorado PUC NG911 Notice Comments at 4 (emphasis 
omitted).
---------------------------------------------------------------------------

    The phased approach we adopt is consistent with phased approaches 
recommended by Intrado and MSCI, with minor adjustments to accommodate 
our regulatory goal of encompassing current and future NG911 commonly 
accepted standards. Intrado states that ``NG911 delivery is divisible 
into two distinct stages--(1) IP transit (i.e., SIP delivery to the 
POI) and (2) NG911-formatted call information under

[[Page 78082]]

the i3 standard, with the former being a prerequisite for the latter.'' 
MSCI suggests that the Commission consider ``a two-step approach to 
NG911 deployment. The first step would involve a requirement that an 
OSP deliver 911 calls in IP format [upon request of a 911 Authority] . 
. . . The second step would involve a requirement that an OSP deliver 
911 calls consistent with NENA i3 standard . . . .'' The rules are very 
similar to Intrado's and MSCI's recommendations.
    NASNA proposed a three-phase approach in which the initial phase 
would be triggered when the 911 Authority has an ESInet that is ready 
to receive 911 calls from the OSPs via an LNG. Colorado PUC similarly 
contemplates a phase in which 911 Authorities would maintain an LNG. We 
conclude that incorporating this initial phase into our rules is 
unnecessary and potentially counterproductive, as it merely describes 
the earliest transitional stage in which 911 Authorities continue to 
maintain LNGs to accommodate OSPs that have not transitioned to IP. We 
agree with MSCI that including this ``legacy phase'' could ``prolong 
the migration.'' \205\ Instead, Phase 1 and Phase 2 in our rules 
correspond to the second and third phases proposed by NASNA, which call 
for OSPs to first support basic SIP and then support SIP that complies 
with NG911 commonly accepted standards.
---------------------------------------------------------------------------

    \205\ Mission Critical Partners NG911 Notice Comments at 8-9 
(citing NASNA Petition).
---------------------------------------------------------------------------

    We prefer the two-phase approach to the single-phase approach 
proposed in the LBR Notice and NG911 Notice because a single-phase 
approach is less capable of encompassing the sequencing of steps that 
both 911 Authorities and OSPs must take during the NG911 transition. As 
discussed by several commenters, a phased regulatory approach aligns 
with the typical multi-phased implementation of NG911. In addition, we 
find it unnecessary to seek further comment on whether to adopt a 
phased approach, given that the Commission sought comment on NASNA's 
phased recommendation in the NG911 Notice and has gathered an adequate 
record for decision.\206\ We additionally conclude that, in light of 
the extensive record in this proceeding, an industry task force is not 
needed to further study these NG911 rules. We also find that a two-
phased approach will not needlessly slow the transition to NG911, as 
argued by APCO, as the phased approach we adopt will ensure that OSPs 
and 911 Authorities take the necessary steps at each phase of the 
transition to NG911.
---------------------------------------------------------------------------

    \206\ NG911 Notice, 38 FCC Rcd at 6224-25, para. 41.
---------------------------------------------------------------------------

    We affirm the Commission's reasoning in the LBR Notice and NG911 
Notice that IP delivery requirements will advance the transition to 
NG911 by alleviating the burden on 911 Authorities to maintain 
transitional gateways and helping 911 Authorities realize the public 
safety benefits of NG911 networks. We agree with iCERT's assertion that 
the need to accommodate TDM-based 911 calls creates added costs for 
state and local 911 authorities, and that the adoption of IP delivery 
requirements will reduce the cost burdens of maintaining and operating 
legacy 911 infrastructure. We also agree with Intrado's assertion that 
establishing direct OSP connectivity via SIP to ESInets ``will 
materially reduce the number of 911 outages through improved network 
reliability and availability.'' \207\ We agree with Comtech that 
maintaining both legacy and IP-based systems for the delivery of 911 
traffic involves significant costs and creates increased vulnerability 
and risk of 911 outages. NENA also states that it is prohibitively 
expensive to maintain TDM and IP networks for 911 simultaneously.

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

    In addition, we affirm the principle of parity in NG911 
requirements for OSPs at Phases 1 and 2, though as discussed in this 
document and section III.C.3 of the Order, differences among types of 
OSPs regarding their current NG911 transition progress and capabilities 
merit adjustment of compliance timelines for some classes of OSPs. 
NENA, iCERT, NASNA, Maine PUC, Colorado PUC, Mission Critical Partners, 
and the Ad Hoc NG911 Service Providers Coalition support parity among 
different types of OSPs. Several commenters indicate that the 
Commission should decline to extend IP delivery requirements to 
wireline and VoIP providers as these services deliver location 
information to 911 Authorities differently than CMRS providers.\208\ We 
note that interconnected VoIP providers already use a LIS functional 
element to transmit location information to 911 Authorities, subject to 
the NENA i2 standard,\209\ and we therefore find arguments that 
interconnected VoIP providers cannot provide location information to 
NG911 networks via a LIS to be unsupported. The record also confirms 
that it is technically feasible for wireline providers to use a LIS to 
transmit location information to 911 Authorities, even when they do not 
originate calls in IP. We also note that nothing under these rules 
changes the existing obligations that all OSPs have to determine the 
location of the 911 caller under the OSP-specific rules in part 9.

b. Phase 1
(i) Requirement
    Upon receipt of a valid Phase 1 request from a 911 Authority, OSPs 
must (i) deliver all 911 traffic bound for the relevant PSAPs in the 
IP-based SIP format requested by the 911 Authority, (ii) obtain and 
deliver 911 traffic to enable the ESInet and other NG911 network 
facilities to transmit all 911 traffic to the destination PSAP, (iii) 
deliver all such 911 traffic to one or more in-state NG911 Delivery 
Points designated by the 911 Authority, and (iv) complete connectivity 
testing to confirm that the 911 Authority receives 911 traffic in the 
IP-based SIP format requested by the 911 Authority. OSPs are not 
required to originate 911 traffic in an IP format, and therefore may 
use a legacy TDM-to-IP gateway (LNG) to achieve compliance with these 
Phase 1 requirements.

    Implementing Phase 1 will help reduce costs and improve 911 
reliability by moving 911 traffic from legacy to IP transmission 
facilities, and will establish the foundation necessary for subsequent 
implementation of Phase 2. MSCI and iCERT argue, and we agree, that 
delivery in IP is a critical first step before compliance with NG911 
commonly accepted standards.\210\ Intrado asserts that IP delivery will 
``materially reduce the number of 911 outages through improved network 
reliability.'' Mission Critical Partners, iCERT, Comtech, and the State 
of Minnesota Department of Public Safety-Emergency Communication 
Networks (Minnesota DPS-ECN) indicate that relieving 911 Authorities of 
the burden of supporting TDM traffic from OSPs will materially reduce 
costs to those 911 Authorities.

    To the extent that OSPs originate 911 traffic in TDM, we find that 
they should be responsible in Phase 1 for translating such traffic to 
SIP when delivering it to the designated NG911 Delivery Point. We 
disagree with Verizon's argument that requiring each individual TDM-
based OSP to provide an LNG ``imposes unnecessary costs on OSPs'' and 
that ``LNG capabilities should thus presumptively remain the PSAP/NG911 
provider's responsibility.'' \211\ As most OSPs already transmit 
traffic via SIP, it is unreasonable to require 911 Authorities to 
maintain LNGs for the small number of OSPs that continue to originate 
and transmit their traffic in TDM. In addition, we find that it is not 
unreasonably costly for OSPs that originate and transmit traffic in TDM 
to maintain an LNG or contract with a third party to translate 911 
traffic. We find that it should be the responsibility of the OSP to 
translate 911 traffic from legacy formats and deliver 911 traffic in 
the SIP format requested by the 911 Authority. However, nothing in our 
rules prevents a 911 Authority from continuing to host an LNG for OSPs 
to use, either through an alternative agreement with an OSP or by 
choosing not to use the valid request mechanism in our rules. This 
possibility was noted by CSRIC, which observed that a 911 Authority's 
ESInet provider ``can provide the LNG as a service and

[[Page 78084]]

accommodate small carriers coming on board with minimal expense to the 
smaller carrier.'' \212\

    Connectivity Testing. As part of Phase 1, we require OSPs to 
conduct connectivity testing to confirm that the 911 Authority receives 
911 traffic in the IP-based SIP format requested by the 911 Authority. 
Such testing will help to ensure that the connection from the OSP to 
the 911 Authority is implemented correctly and meets the requirements 
of the 911 Authority. The Commission sought comment on testing related 
to NG911 delivery in the LBR Notice and NG911 Notice.\213\ Several 
commenters emphasize the importance of connectivity testing as part of 
the process of initiating delivery of 911 traffic to ESInets.\214\ 
Commenters also note that connectivity testing will require 
cooperation, coordination, and collaboration among multiple parties, 
including OSPs, NG911 vendors, and 911 Authorities.\215\ Because the 
ability of OSPs to complete testing within the required time period 
depends on such cooperation, we condition the testing requirement on 
911 Authorities securing commitments from their NG911 vendors to ensure 
that such vendors are available to complete connectivity testing by the 
compliance deadline applicable to the OSP.

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

(ii) Definitions
    To facilitate compliance with our rules for Phase 1 delivery, we 
adopt definitions for ``911 traffic,'' ``NG911 Delivery Point,'' and 
``Session Initiation Protocol (SIP).'' Adopting functional definitions 
of these terms will provide guidance to OSPs in complying with our cost 
allocation and IP-delivery rules and will assist both OSPs and 911 
Authorities by providing baseline definitions of important technical 
terms relevant to their needs. We define the term ``911 traffic'' as a 
convenient descriptor of the transmissions regulated under these rules. 
We similarly define the term ``NG911 Delivery Point'' as a convenient 
descriptor of the point to which an OSP's 911 traffic is delivered. 
While several commenters called for definitions of the terms ``IP-
capable,'' ``IP-based,'' and ``NG911-capable,'' \216\ the term ``SIP'' 
is a standard technical term used in NG911 reference materials.\217\ 
``SIP'' was also used by several other commenters in the record.\218\ 
We believe that referencing ``SIP'' to describe IP delivery and 911 
Authority readiness at Phases 1 and 2 and defining that term will 
provide clarity regarding the Commission's NG911 rules, as it is a 
technically more precise term than ``IP-based format'' and similar 
terms.

(``SIP connectivity is a foundational building block for NG911.''); 
Intrado NG911 Notice Reply at 3 (rec. Sept. 8, 2023) (Intrado NG911 
Notice Reply) (explaining its proposal that the first stage of PSAP 
readiness would be that a 911 Authority is ``ready to certify that 
it can receive IP-formatted (i.e., SIP) traffic at the designated IP 
POI''). Regarding IP Service Delivery, NASNA urged the Commission to 
assist with the transition to NG911 by, among other things, amending 
the Commission's rules to ``specifically address NG911, including 
the standardized requirements associated with NG911 (e.g., Session 
Initiation Protocol [SIP] format and provide location information 
attached to the SIP header of the call using Presence Information 
Data Format Location Object [PIDF-LO]).'' NG911 Notice, 38 FCC Rcd 
at 6214-15, para. 20 (citing NASNA Petition at 4-5).
---------------------------------------------------------------------------

    We find that defining these terms will help to clarify our NG911 
requirements and assist parties with compliance. Accordingly, we adopt 
the following definitions:

<bullet> 911 traffic. Transmissions 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 information about calling parties' locations and 
originating telephone numbers and routing information transmitted with 
the calls and/or text messages.
<bullet> NG911 Delivery Point. A geographic location, facility, or 
demarcation point designated by a 911 Authority where an originating 
service provider shall transmit and deliver 911 traffic in an IP format 
to ESInets or other NG911 network facilities.
<bullet> Session Initiation Protocol (SIP). A signaling protocol used 
for initiating, maintaining, modifying, and terminating communications 
sessions between internet Protocol (IP) devices. SIP enables voice, 
messaging, video, and other communications services between two or more 
endpoints on IP networks.
c. Phase 2
(i) Requirement
    Upon receipt of a 911 Authority's valid Phase 2 request, OSPs must 
deliver all 911 traffic bound for the relevant PSAPs to NG911 Delivery 
Points designated by the 911 Authority in an IP-based SIP format that 
complies with NG911 commonly accepted standards identified by the 911 
Authority, including having location information embedded in the call 
signaling using Presence Information Data Format--Location Object 
(PIDF-LO) \219\ or its functional equivalent. OSPs must also either (1) 
install and put into operation all equipment, software applications, 
and other infrastructure necessary to use a LIS or its functional 
equivalent for the verification of their customer location information 
and records, or (2) acquire services that can be used for the same 
purpose. In addition, OSPs must complete connectivity testing to 
confirm that the 911 Authority receives 911 traffic in the IP-based SIP 
format that complies with the identified NG911 commonly accepted 
standards. Because Phase 2 builds upon Phase 1, and completion of Phase 
1 is a prerequisite for Phase 2, the OSP must also continue to comply 
with Phase 1 requirements during Phase 2, including the requirement to 
deliver all such 911 traffic to NG911 Delivery Points designated by the 
911 Authority. Phase 2 will facilitate the full use of the functional 
elements of NGCS, including LVF, which can deliver more dynamic and 
actionable information to PSAPs than legacy ALI databases, and policy 
routing functions that can dynamically reroute 911 calls and texts in 
response to real-time events. This will eliminate the need for 911 
Authorities to maintain legacy ANI and ALI components and will provide 
PSAPs with greater

[[Page 78085]]

flexibility to avoid network disruptions and reduce the impact of 
outages on 911 continuity.
---------------------------------------------------------------------------

    \219\ See RFC 4119.
---------------------------------------------------------------------------

    We provide the below illustrative diagram to demonstrate the main 
high-level functions covered at Phase 2. This diagram is not meant to 
represent required network architectures in an ``as built'' 
configuration and is not prescriptive in nature. The call flow is 
illustrated by blue lines representing SIP 911 traffic and red lines 
indicating legacy 911 traffic. In the below diagram, 911 traffic 
originates on the left side of the diagram and flows from left to 
right.
[GRAPHIC] [TIFF OMITTED] TR24SE24.003

    The above diagram uses the following acronyms:

<bullet> ANI = Automatic Number Identification
<bullet> ALI = Automatic Location Information
<bullet> BCF = Border Control Function
<bullet> ECRF = Emergency Call Routing Function
<bullet> ESInet = Emergency Services IP Network
<bullet> ESRP = Emergency Services Routing Proxy
<bullet> GIS = Geographic Information System
<bullet> IMS = IP Multimedia Subsystem
<bullet> LIS = Location Information Server
<bullet> LNG = Legacy Network Gateway
<bullet> LPG = Legacy PSAP Gateway
<bullet> LVF = Location Validation Function
<bullet> MSAG = Master Street Address Guide
<bullet> NG PSAP = Next Generation 911 PSAP
<bullet> NGCS = NG911 Core Services
<bullet> PRF = Policy Routing Function

    OSPs may comply with Phase 2 either by originating 911 traffic in 
IP format or by maintaining or accessing an LNG to convert the traffic 
in order to deliver 911 traffic in SIP format that complies with the 
NG911 commonly accepted standards identified by the requesting 911 
Authority. This addresses a concern raised by several commenters that 
requiring IP origination, as opposed to delivery, could be burdensome 
for some wireline providers.\220\ Although some commenters support an 
origination requirement,\221\ AT&T notes that this could require 
certain OSPs to make ``inefficient alterations to network components 
that are nearing end-of-life.'' USTelecom states that in some instances 
OSPs would have to ``overbuild their existing networks with fiber on an 
abbreviated timeline, a proposition that is not only unnecessary but 
would be extremely costly.'' USTelecom also notes that some wireline 
providers have carrier of last resort (COLR) obligations ``prohibiting 
them from retiring legacy networks and technology.'' We agree that in 
light of these considerations, IP origination should be encouraged but 
not required, so long as OSPs ensure that 911 calls originated in TDM 
are translated and delivered in SIP format. Therefore, in both Phase 1 
and Phase 2, we permit OSPs to choose between upgrading networks to 
enable IP origination or converting their TDM traffic to IP before 
delivery to the NG911 network.\222\

    The Competitive Carriers Association (CCA) questions whether the 
Commission provided sufficient notice of a proposed requirement for 
wireless carriers to translate 911 traffic to IP.\223\ We find that 
both the NG911 Notice and LBR Notice clearly proposed requirements for 
TDM-based wireless carriers to translate 911 traffic to IP. The 
proposed rules in the LBR Notice specified that CMRS providers would be 
required to deliver calls in the requested IP-based format.\224\ In the 
NG911 Notice, the Commission proposed that valid requests by 911 
Authorities for IP-based service would trigger obligations for all 
OSPs, including CMRS providers.\225\ Therefore, there has been 
sufficient notice, and the Commission finds CCA's concern unwarranted.

disagree. There are several commercially available solutions that offer 
LIS services to wireline providers, as well as gateway products for 
translating calls from TDM to IP with the inclusion of location 
data.\227\ We therefore find that it is technically feasible for 
wireline providers to provide location information to 911 Authorities 
in a format that complies with NG911 commonly accepted standards. 
Further, we agree with NCTA that ``any provider that continues to 
originate traffic in TDM format should bear responsibility for adding

    We decline to adopt the Texas 9-1-1 Entities' alternative proposal 
to establish different requirements for OSPs that already are capable 
of originating 911 calls in IP format versus OSPs that continue to rely 
on legacy TDM switching facilities for voice traffic within their 
networks.\231\ Under the Texas 9-1-1 Entities proposal, IP-capable OSPs 
would be required to fully support delivery of 911 calls in Phase 2 
NG911 format, but non-IP capable OSPs would deliver calls to LNGs 
designated by 911 Authorities or their NG911 service providers. The 911 
Authorities or their service providers would be responsible for 
operating the LNGs, which would translate the 911 calls into IP format. 
We decline to adopt this proposal because it would require 911 
Authorities to continue to operate and maintain LNGs to support a small 
number of TDM-based OSPs, thereby incentivizing OSPs to continue to 
maintain legacy infrastructure, increase costs, and lengthen the time 
to transition to NG911.\232\ Instead, our rules appropriately shift the 
burden of maintaining translation gateways to those OSPs that continue 
to originate legacy 911 calls that require translation.\233\

    Connectivity testing. In Phase 2, we require OSPs to complete 
connectivity testing to confirm that the 911 Authority receives 911 
traffic in the IP-based SIP format that complies with the NG911 
commonly accepted standards identified by the requesting 911 Authority. 
Such testing is important to ensure that the connection from the OSP to 
the 911 Authority is implemented correctly and meets the requirements 
of the 911 Authority. Several commenters raise the importance of 
testing as part of the process of initiating delivery of 911 traffic to 
ESInets in a way that complies with NG911 commonly accepted standards. 
As with Phase 1 valid requests, we also adopt a condition prerequisite 
that 911 Authorities secure commitments from their NG911 vendors at 
Phase 2 in order to ensure that such vendors are available to complete 
connectivity testing by the compliance deadline applicable to the OSP.
(ii) Definitions
    To facilitate Phase 2 implementation, there are definitions of 
``Functional Element,'' ``Location Information Server (LIS),'' and 
``Location Validation Function (LVF)'' in the NG911 regulations in this 
document and the Order. In the LBR Notice and NG911 Notice, the 
Commission proposed to

[[Page 78087]]

require OSPs to complete all translation necessary to deliver 911 
calls, including associated location information, in the requested IP-
based format to an ESInet or other designated point(s) that allow 
emergency calls to be answered upon request of 911 authorities who have 
established the capability to accept NG911-compatible, IP-based 911 
communications.\234\ We are establishing functional requirements to 
facilitate the provision of location information with 911 traffic for 
Phase 2.\235\ Under our Phase 2 default rules, LIS based location 
validation uses LVF, and this interaction is analogous to the 
interaction between the ANI/ALI database and MSAG in the E911 context. 
However, in the NG911 environment, LVF replaces the functionality of 
the MSAG. Given the extent to which our rules use these terms, we find 
that defining them will provide greater certainty and clarity regarding 
our NG911 requirements and will assist parties in complying with our 
rules. To codify our approach, we adopt a definition of ``functional 
elements'' that will be part of our definitions for LIS and LVF. 
Accordingly, we adopt the following definitions for these terms:
---------------------------------------------------------------------------

    \234\ LBR Notice, 37 FCC Rcd at 15203, 15215, para. 52, app. A; 
NG911 Notice, 38 FCC Rcd at 6215, para. 21.
    \235\ Under our part 9 rules, dispatchable location refers to 
``[a] location delivered to the PSAP with a 911 call that consists 
of the validated street address of the calling party, plus 
additional information such as suite, apartment or similar 
information necessary to adequately identify the location of the 
calling party, except for Commercial Mobile Radio Service providers, 
which shall convey the location information required by Subpart C of 
this Part.'' 47 CFR 9.3. Under rule 9.10(i), dispatchable location 
refers to ``[a] location delivered to the PSAP by the CMRS provider 
with a 911 call that consists of the street address of the calling 
party, plus additional information such as suite, apartment or 
similar information necessary to adequately identify the location of 
the calling party. The street address of the calling party must be 
validated and, to the extent possible, corroborated against other 
location information prior to delivery of dispatchable location 
information by the CMRS provider to the PSAP.'' 47 CFR 9.10(i).

    <bullet> Functional Element. A set of software features that may be 
combined with hardware interfaces and operations on those interfaces to 
accomplish a defined task.
    <bullet> Location Information Server (LIS). 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.
    <bullet> Location Validation Function (LVF). A Functional Element 
in an NG911 Core Services (NGCS) consisting of a server where civic 
location information is validated against the authoritative Geographic 
Information System (GIS) database information. A civic address is 
considered valid if it can be located within the database uniquely, is 
suitable to provide an accurate route for an emergency call, and is 
adequate and specific enough to direct responders to the right 
location.
d. Modification of Phase Requirements by Mutual Agreement
    We encourage OSPs and 911 Authorities to collaborate throughout the 
transition to NG911. To facilitate such collaboration, and consistent 
with our proposals in the NG911 Notice and LBR Notice, we permit 911 
Authorities and OSPs to enter into mutual agreements specifying 
requirements, timetables, and other terms that are different from the 
Phase 1 and Phase 2 rules in this document and the Order. Commenters 
confirm that such flexibility is important to address unique or 
unforeseen challenges that OSPs may face in transitioning from legacy 
911 to NG911.\236\ The alternative agreement rule provides additional 
flexibility beyond what was proposed in the NG911 Notice and LBR 
Notice, which focused on alternative agreements establishing different 
compliance timeframes for OSPs, as well as different cost recovery 
mechanisms for certain providers.\237\ The rules allow 911 Authorities 
and OSPs to mutually address specific concerns beyond timeframes for 
compliance, including designation of NG911 delivery points or cost 
allocation for OSPs. We find that this additional flexibility should be 
beneficial to both 911 Authorities and OSPs.

the rules should permit a more lenient timeline if a state or local 
911 authority determines that a different timeline is appropriate); 
BRETSA NG911 Notice Reply at ii (recommending that states be given 
the flexibility to adopt rules that diverge from the Commission's 
default requirements as necessitated by state policy); Verizon NG911 
Notice Reply at 3 (stressing the need for flexibility in deadlines 
due to unforeseen challenges); CTIA NG911 Notice Reply at 7 (stating 
that OSPs and PSAPs need flexibility to work through various 
implementation and testing issues); AT&T NG911 Notice Comments at 7 
(stating that timetables should be adaptable to unforeseen 
circumstances); and Alaska Telecom Assoc. NG911 Notice Comments at 7 
(discussing unique challenges in Alaska).

(e)); LBR Notice, 37 FCC Rcd at 15202, 15216, para. 50, app. A 
(Sec.  9.10(s)(6)(iii)).
---------------------------------------------------------------------------

    When OSPs and 911 Authorities enter into an alternative agreement, 
we require OSPs to notify the Commission of the agreement and its 
pertinent terms, as was proposed in the NG911 Notice and LBR 
Notice,\238\ within 30 days of the date of execution of the agreement. 
We also require that the notice specifically identify each provision of 
the agreement that differs from the rules. Mission Critical Partners 
recommends that for certain deployment agreements, ``an explanation and 
detailed plan with a timeline should be included and provided to the 
Commission and the 911 authority requesting the service.'' We permit 
but do not require that the actual plans and timeline documents 
themselves be provided to the Commission. We delegate authority to 
PSHSB to issue instructions for OSPs to provide notification to the 
Commission of the modification of the agreement and its pertinent 
terms.

e. Internet-Based TRS Providers
    The Phase 1 and Phase 2 requirements apply to internet-based TRS 
providers. However, ClearCaptions and Hamilton Relay point out that 
whereas most internet-based TRS providers directly support 911 calling, 
internet Protocol Captioned Telephone Service providers generally rely 
on underlying providers for routing emergency calls.\239\ We therefore 
clarify that Phase 1 and Phase 2 requirements only apply to internet-
based TRS providers that are directly involved with routing 911 
traffic, pursuant to part 9, subpart E of the Commission's rules.

    Brian Rosen suggests that the Commission take additional steps to 
impose additional requirements on IP CTS, IP Relay, and 
videoconferencing services. We did not make such proposals in the NG911 
Notice and therefore decline to take such steps at this time as they 
are outside the scope of this proceeding.
2. Valid Requests for Delivery of 911 Traffic in IP-Based Transmission 
Formats
    We adopt rules defining the prerequisites that 911 Authorities must 
meet in order to make a valid request to OSPs for compliance with the 
requirements of Phase 1 and Phase 2. In the LBR Notice and NG911 
Notice, the Commission proposed that for a 911 Authority request to be 
deemed valid, the 911 Authority would certify that it (1) is 
technically ready to receive 911 calls and texts in the IP-based format 
requested, (2) is specifically authorized

[[Page 78088]]

to accept calls and/or texts in the IP-based format requested, and (3) 
has provided notification to the OSPs receiving the request that it 
meets these requirements.\240\ The Commission also sought comment on 
whether other prerequisites were needed to determine a 911 Authority's 
readiness.\241\
---------------------------------------------------------------------------

Notice, 38 FCC Rcd at 6224, para. 40.
    \241\ LBR Notice, 37 FCC Rcd at 15203, para. 51; NG911 Notice, 
38 FCC Rcd at 6225-26, para. 42.
---------------------------------------------------------------------------

    For both Phases 1 and 2, we adopt the three general prerequisites 
for a valid request proposed in the LBR Notice and NG911 Notice: 
technical readiness, authorization, and notification. We adopt a valid 
request definition at each phase that specifies the functional 
requirements that NG911 networks m
