§  9.14   Emergency calling requirements.

   (a) Emergency call handling requirements for TTY-based TRS providers.
   TTY-based TRS providers must use a system for incoming emergency calls
   that, at a minimum, automatically and immediately transfers the caller
   to an appropriate Public Safety Answering Point (PSAP). An appropriate
   PSAP is either a PSAP that the caller would have reached if the caller
   had dialed 911 directly, or a PSAP that is capable of enabling the
   dispatch of emergency services to the caller in an expeditious manner.

   (b) Additional emergency calling requirements applicable to
   internet-based TRS providers. (1) The requirements of paragraphs
   (b)(2)(i) and (iv) of this section shall not apply to providers of VRS
   and IP Relay to which § 9.14(c) and (d) apply.

   (2) Each provider of internet-based TRS shall:

   (i) When responsible for placing or routing voice calls to the public
   switched telephone network, accept and handle emergency calls and
   access, either directly or via a third party, a commercially available
   database that will allow the provider to determine an appropriate PSAP,
   designated statewide default answering point, or appropriate local
   emergency authority that corresponds to the caller's location, and to
   relay the call to that entity;

   (ii) Implement a system that ensures that the provider answers an
   incoming emergency call before other non-emergency calls (i.e.,
   prioritize emergency calls and move them to the top of the queue);

   (iii) Provide 911 and E911 service in accordance with paragraphs (c)
   through (e) of this section, as applicable;

   (iv) Deliver to the PSAP, designated statewide default answering point,
   or appropriate local emergency authority, at the outset of the outbound
   leg of an emergency call, at a minimum, the name of the relay user and
   location of the emergency, as well as the name of the relay provider,
   the CA's callback number, and the CA's identification number, thereby
   enabling the PSAP, designated statewide default answering point, or
   appropriate local emergency authority to re-establish contact with the
   CA in the event the call is disconnected;

   (v) In the event one or both legs of an emergency call are disconnected
   (i.e., either the call between the TRS user and the CA, or the outbound
   voice telephone call between the CA and the PSAP, designated statewide
   default answering point, or appropriate local emergency authority),
   immediately re-establish contact with the TRS user and/or the
   appropriate PSAP, designated statewide default answering point, or
   appropriate local emergency authority and resume handling the call; and

   (vi) Ensure that information obtained as a result of this section is
   limited to that needed to facilitate 911 services, is made available
   only to emergency call handlers and emergency response or law
   enforcement personnel, and is used for the sole purpose of ascertaining
   a user's location in an emergency situation or for other emergency or
   law enforcement purposes.

   (c) E911 Service for VRS and IP Relay before January 6, 2021, for fixed
   services, and before January 6, 2022, for non-fixed services—(1) Scope.
   The following requirements of paragraphs (c)(1) through (4) of this
   section are only applicable to providers of VRS or IP Relay. Further,
   these requirements apply only to 911 calls placed by registered users
   whose Registered Location is in a geographic area served by a Wireline
   E911 Network and is available to the provider handling the call.

   (2) E911 Service. VRS or IP Relay providers must, as a condition of
   providing service to a user:

   (i) Provide that user with E911 service as described in this section;

   (ii) Request, at the beginning of each emergency call, the caller's
   name and location information, unless the VRS or IP Relay provider
   already has, or has access to, Registered Location information for the
   caller;

   (iii) Transmit all 911 calls, as well as ANI, the caller's Registered
   Location, the name of the VRS or IP Relay provider, and the CA's
   identification number for each call, to the PSAP, designated statewide
   default answering point, or appropriate local emergency authority that
   serves the caller's Registered Location and that has been designated
   for telecommunications carriers pursuant to § 9.4, provided that “all
   911 calls” is defined as “any communication initiated by an VRS or IP
   Relay user dialing 911”;

   (iv) Route all 911 calls through the use of ANI and, if necessary,
   pseudo-ANI, via the dedicated Wireline E911 Network, provided that
   nothing in this subparagraph shall preclude routing the call first to a
   call center to ascertain the caller's location in the event that the
   VRS or IP Relay provider believes the caller may not be located at the
   Registered Location; and

   (v) Make the Registered Location, the name of the VRS or IP Relay
   provider, and the CA's identification number available to the
   appropriate PSAP, designated statewide default answering point, or
   appropriate local emergency authority from or through the appropriate
   automatic location information (ALI) database.

   (3) Service level obligation. Notwithstanding the provisions in
   paragraph (c)(2) of this section, if a PSAP, designated statewide
   default answering point, or appropriate local emergency authority is
   not capable of receiving and processing either ANI or location
   information, a VRS or IP Relay provider need not provide such ANI or
   location information; however, nothing in this paragraph affects the
   obligation under paragraph (c)(2)(iv) of this section of a VRS or IP
   Relay provider to transmit via the Wireline E911 Network all 911 calls
   to the PSAP, designated statewide default answering point, or
   appropriate local emergency authority that serves the caller's
   Registered Location and that has been designated for telecommunications
   carriers pursuant to § 9.4.

   (4) Registered location requirement. VRS and IP Relay providers must:

   (i) Obtain from each Registered internet-based TRS user, prior to the
   initiation of service, the physical location at which the service will
   first be used; and

   (ii) If the VRS or IP Relay is capable of being used from more than one
   location, provide their registered internet-based TRS users one or more
   methods of updating the user's Registered Location, including at least
   one option that requires use only of the iTRS access technology
   necessary to access the VRS or IP Relay. Any method used must allow a
   registered internet-based TRS user to update the Registered Location at
   will and in a timely manner.

   (d) E911 Service for VRS and IP Relay on or after January 6, 2021, for
   fixed services, and on or after January 6, 2022, for non-fixed
   services—(1) Scope. The following requirements of paragraphs (d)(1)
   through (4) of this section are only applicable to providers of VRS or
   IP Relay. Further, these requirements apply only to 911 calls placed by
   registered users whose dispatchable location is in a geographic area
   served by a Wireline E911 Network and is available to the provider
   handling the call.

   (2) E911 Service. VRS or IP Relay providers must, as a condition of
   providing service to a user:

   (i) Provide that user with E911 service as described in this section;

   (ii) Request, at the beginning of each emergency call, the caller's
   name and dispatchable location, unless the VRS or IP relay provider
   already has, or has access to the location information described in
   paragraph (d)(4) of this section;

   (iii) Transmit the following to the PSAP, designated statewide default
   answering point, or appropriate local emergency authority that serves
   the caller's dispatchable location and that has been designated for
   telecommunications carriers pursuant to § 9.4:

   (A) All 911 calls, provided that “all 911 calls” is defined as “any
   communication initiated by an VRS or IP Relay user dialing 911;”

   (B) ANI, the name of the VRS or IP Relay provider, and the CA's
   identification number for each call; and

   (C) The location information described in paragraph (d)(4) of this
   section.

   (iv) Route all 911 calls through the use of ANI and, if necessary,
   pseudo-ANI, via the dedicated Wireline E911 Network, provided that
   nothing in this subparagraph shall preclude routing the call first to a
   call center to ascertain the caller's location in the event that the
   VRS or IP Relay provider is unable to obtain or confirm the caller's
   location information; and

   (v) Make the location information described in paragraph (d)(4) of this
   section, the name of the VRS or IP Relay provider, and the CA's
   identification number available to the appropriate PSAP, designated
   statewide default answering point, or appropriate local emergency
   authority from or through the appropriate automatic location
   information (ALI) database.

   (3) Service level obligation. Notwithstanding the provisions in
   paragraph (d)(2) of this section, if a PSAP, designated statewide
   default answering point, or appropriate local emergency authority is
   not capable of receiving and processing either ANI or location
   information, a VRS or IP Relay provider need not provide such ANI or
   location information; however, nothing in this paragraph affects the
   obligation under paragraph (d)(2)(iv) of this section of a VRS or IP
   Relay provider to transmit via the Wireline E911 Network all 911 calls
   to the PSAP, designated statewide default answering point, or
