§ 64.605   Emergency calling requirements.

   (a) Additional emergency calling requirements applicable to internet-based
   TRS providers. (1) As of December 31, 2008, the requirements of paragraphs
   (a)(2)(i) and (a)(2)(iv) of this section shall not apply to providers of VRS
   and IP Relay to which § 64.605(b) applies.

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

   (i) 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) Request, at the beginning of each emergency call, the caller's name
   and location information, unless the Internet-based TRS provider already
   has, or has access to, a Registered Location for the caller;

   (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.

   (b) E911 Service for VRS and IP Relay—(1) Scope. The following requirements
   are only applicable to providers of VRS or IP Relay. Further, the following
   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. As of December 31, 2008:

   (i) VRS or IP Relay providers must, as a condition of providing service to a
   user, provide that user with E911 service as described in this section;

   (ii) VRS or IP Relay providers must 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 § 64.3001 of this chapter,
   provided that “all 911 calls” is defined as “any communication initiated by
   an VRS or IP Relay user dialing 911”;

   (iii) All 911 calls must be routed through the use of ANI and, if necessary,
   pseudo-ANI, via the dedicated Wireline E911 Network; and

   (iv) The Registered Location, the name of the VRS or IP Relay provider, and
   the CA's identification number must be 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
   (b)(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) 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 § 64.3001 of this chapter.

   (4) Registered location requirement. As of December 31, 2008, 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 utilized; 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 their 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 utilized must allow a registered Internet-based
   TRS user to update the Registered Location at will and in a timely manner.
