§ 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.
