Definitions and provisions of general applicability.
(a) For purposes of this subpart, the terms Public Safety Answering Point (PSAP), statewide default answering point, and appropriate local emergency authority are defined in 47 CFR 64.3000; the terms pseudo-ANI and Wireline E911 Network are defined in 47 CFR 9.3; the term affiliate is defined in 47 CFR 52.12(a)(1)(i), and the terms majority and debt are defined in 47 CFR 52.12(a)(1)(ii).
(1) 711. The abbreviated dialing code for accessing relay services anywhere in the United States.
(2) 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.
(3) ANI. For 911 systems, the Automatic Number Identification (ANI) identifies the calling party and may be used as the callback number.
(4) ASCII. An acronym for American Standard Code for Information Interexchange which employs an eight bit code and can operate at any standard transmission baud rate including 300, 1200, 2400, and higher.
(5) Baudot. A seven bit code, only five of which are information bits. Baudot is used by some text telephones to communicate with each other at a 45.5 baud rate.
(6) Call release. A TRS feature that allows the CA to sign-off or be “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.
(7) 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 carrier engaged in intrastate communication by wire or radio, notwithstanding sections 2(b) and 221(b) of the Act.
(8) Communications assistant (CA). A person who transliterates or interprets conversation between two or more end users of TRS. CA supersedes the term “TDD operator.”
(9) Hearing carry over (HCO). A form of TRS where the person with the speech disability is able to listen to the other end user and, in reply, the CA speaks the text as typed by the person with the speech disability. The CA does not type any conversation. Two-line HCO is an 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 conversation to take place between an HCO user and a TTY user. HCO-to-HCO allows a relay conversation to take place between two HCO users.
(10) Interconnected VoIP service. An interconnected Voice over Internet protocol (VoIP) service is a service that:
(ii) Requires a broadband connection from the user's location;
(iii) Requires Internet protocol-compatible customer premises equipment (CPE); and
(iv) Permits users generally to receive calls that originate on the public switched telephone network and to terminate calls to the public switched telephone network.
(11) Internet-based TRS. A telecommunications relay service (TRS) in which an individual with a hearing or a speech disability connects to a TRS communications assistant using an Internet Protocol-enabled device via the Internet, rather than the public switched telephone network. Internet-based TRS does not include the use of a text telephone (TTY) over an interconnected voice over Internet Protocol service.
(12) Internet Protocol Captioned Telephone Service (IP CTS). A telecommunications relay service that permits an individual who can speak but who has difficulty hearing over the telephone to use a telephone and an Internet Protocol-enabled device via the Internet to simultaneously listen to the other party and read captions of what the other party is saying. With IP CTS, the connection carrying the captions between the relay service provider and the relay service user is via the Internet, rather than the public switched telephone network.
(13) Internet Protocol Relay Service (IP Relay). A telecommunications relay service that permits an individual with a hearing or a speech disability to communicate in text using an Internet Protocol-enabled device via the Internet, rather than using a text telephone (TTY) and the public switched telephone network.
(14) Non-English language relay service. A telecommunications relay service that allows persons with hearing or speech disabilities who use languages other than English to communicate with voice telephone users in a shared language other than English, through a CA who is fluent in that language.
(15) Numbering Partner. Any entity with which an Internet-based TRS provider has entered into a commercial arrangement to obtain North American Numbering Plan telephone numbers.
(16) Qualified interpreter. An interpreter who is able to interpret effectively, accurately, and impartially, both receptively and expressively, using any necessary specialized vocabulary.
(17) Registered Location. The most recent information obtained by a VRS or IP Relay provider that identifies the physical location of an end user.
(18) Registered Internet-based TRS User. An individual that has registered with a VRS or IP Relay provider as described in § 64.611 of this chapter.
(19) Speech-to-speech relay service (STS). A telecommunications relay service that allows individuals with speech disabilities to communicate with voice telephone users through the use of specially trained CAs who understand the speech patterns of persons with speech disabilities and can repeat the words spoken by that person.
(20) Speed dialing. A TRS feature that allows a TRS user to place a call using a stored number maintained by the TRS facility. In the context of TRS, speed dialing allows a TRS user to give the CA a short-hand” name or number for the user's most frequently called telephone numbers.
(21) Telecommunications relay services (TRS). Telephone transmission services that provide the ability for an individual who has a hearing or speech disability to engage in communication by wire or radio with a hearing individual in a manner that is functionally equivalent to the ability of an individual who does not have a hearing or speech disability to communicate using voice communication services by wire or radio. Such term includes services that enable two-way communication between an individual who uses a text telephone or other nonvoice terminal device and an individual who does not use such a device, speech-to-speech services, video relay services and non-English relay services. TRS supersedes the terms “dual party relay system,” “message relay services,” and “TDD Relay.”
(22) Text telephone (TTY). A machine that employs graphic communication in the transmission of coded signals through a wire or radio communication system. TTY supersedes the term “TDD” or “telecommunications device for the deaf,” and TT.
(23) Three-way calling feature. A TRS feature that allows more than two parties to be on the telephone line at the same time with the CA.
(24) TRS Numbering Administrator. The neutral administrator of the TRS Numbering Directory selected based on a competitive bidding process.
(25) TRS Numbering Directory. The database administered by the TRS Numbering Administrator, the purpose of which is to map each Registered Internet-based TRS User's NANP telephone number to his or her end device.
(26) 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.
(27) 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.
(28) 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.
(b) For purposes of this subpart, all regulations and requirements applicable to common carriers shall also be applicable to providers of interconnected VoIP service.
