   essential call center function of call distribution, and that are a
   necessary core component of Internet-based TRS.

   (3) American Sign Language (ASL). A visual language based on hand
   shape, position, movement, and orientation of the hands in relation to
   each other and the body.

   (4) ANI. For 911 systems, the Automatic Number Identification (ANI)
   identifies the calling party and may be used as the callback number.

   (5) ASCII. An acronym for American Standard Code for Information

   new default provider, having obtained the user's authorization verified

   “released” from the telephone line after the CA has set up a telephone
   call between the originating TTY caller and a called TTY party, such as
   when a TTY user must go through a TRS facility to contact another TTY
   user because the called TTY party can only be reached through a
   voice-only interface, such as a switchboard.

   (9) Common carrier or carrier. Any common carrier engaged in interstate
   Communication by wire or radio as defined in section 3(h) of the
   Communications Act of 1934, as amended (the Act), and any common

   HCO service that allows TRS users to use one telephone line for hearing
   and the other for sending TTY messages. HCO-to-TTY allows a relay

   identify unique TRS users and to ensure that each has a single default
   provider;

   (ii) Assigning each VRS user a unique identifier;

   (iii) Allowing VRS providers and other authorized entities to query the
   TRS User Registration Database to determine if a prospective user
   already has a default provider;

   (iv) Allowing VRS providers to indicate that a VRS user has used the
   service; and

   (v) Maintaining the confidentiality of proprietary data housed in the

   unauthorized persons. The purpose of this database is to ensure
   accurate registration and verification of VRS users and improve the
   efficiency of the TRS program.

   (45) Unauthorized provider. An iTRS provider that becomes the iTRS
   user's new default provider without having obtained the user's
   authorization verified in accordance with the procedures specified in
   this part.

   (47) Video relay service (VRS). A telecommunications relay service that
   allows people with hearing or speech disabilities who use sign language
   to communicate with voice telephone users through video equipment. The
   video link allows the CA to view and interpret the party's signed
   conversation and relay the conversation back and forth with a voice
   caller.

   (48) Visual privacy screen. A screen or any other feature that is
   designed to prevent one party or both parties on the video leg of a VRS
   call from viewing the other party during a call.

   (49) Voice carry over (VCO). A form of TRS where the person with the
   hearing disability is able to speak directly to the other end user. The
   CA types the response back to the person with the hearing disability.
   The CA does not voice the conversation. Two-line VCO is a VCO service
   that allows TRS users to use one telephone line for voicing and the
   other for receiving TTY messages. A VCO-to-TTY TRS call allows a relay
   conversation to take place between a VCO user and a TTY user.
   VCO-to-VCO allows a relay conversation to take place between two VCO
   users.

   (50) VRS access technology. Any equipment, software, or other
   technology issued, leased, or provided by an Internet-based TRS
   provider that can be used to make and receive a VRS call.

   procured by or on behalf of the Commission that provides VRS
   functionality, including the ability to make and receive VRS and
   point-to-point calls, dial-around functionality, and the ability to
   update user registration location, and against which providers may test
   their own VRS access technology and platforms for compliance with the
   Commission's interoperability and portability rules.

   (b) For purposes of this subpart, all regulations and requirements
   applicable to common carriers shall also be applicable to providers of
   interconnected VoIP service.
