§ 64.613   Numbering directory for Internet-based TRS users.

   (a) TRS Numbering Directory.

   (1) The TRS Numbering Directory shall contain records mapping the
   geographically appropriate NANP telephone number of each Registered
   Internet-based TRS User and hearing point-to-point video user to a
   unique Uniform Resource Identifier (URI).

   (2) For each record associated with a VRS user's geographically
   appropriate NANP telephone number, the URI shall contain a server
   domain name or the IP address of the user's device. For each record
   associated with an IP Relay user's geographically appropriate NANP
   telephone number, the URI shall contain the user's user name and domain
   name that can be subsequently resolved to reach the user.

   (3) Within one year after the effective date of this Order,
   Internet-based TRS providers must ensure that a user's toll free number
   that is associated with a geographically appropriate NANP number will
   be associated with the same URI as that geographically appropriate NANP
   telephone number.

   (4) Only the TRS Numbering Administrator and Internet-based TRS
   providers may access the TRS Numbering Directory.

   (b) Administration—(1) Neutrality. (i) The TRS Numbering Administrator
   shall be a non-governmental entity that is impartial and not an
   affiliate of any Internet-based TRS provider.

   (ii) Neither the TRS Numbering Administrator nor any affiliate may
   issue a majority of its debt to, nor derive a majority of its revenues
   from, any Internet-based TRS provider.

   (iii) Nor may the TRS Numbering Administrator nor any affiliate be
   unduly influenced, as determined by the North American Numbering
   Council, by parties with a vested interest in the outcome of
   TRS-related numbering administration and activities.

   (iv) Any subcontractor that performs any function of the TRS Numbering
   Administrator must also meet these neutrality criteria.

   (2) Terms of Administration. The TRS Numbering Administrator shall
   administer the TRS Numbering Directory pursuant to the terms of its
   contract.

   (3) Compensation. The TRS Fund, as defined by 47 CFR 64.604(a)(5)(iii),
   may compensate the TRS Numbering Administrator for the reasonable costs
   of administration pursuant to the terms of its contract.
