   coordinate-based) sufficient to identify the caller's civic address and
   approximate in-building location, including floor level, in large
   buildings.

   Appropriate local emergency authority. An emergency answering point
   that has not been officially designated as a Public Safety Answering
   Point (PSAP), but has the capability of receiving 911 calls and either
   dispatching emergency services personnel or, if necessary, relaying the
   call to another emergency service provider. An appropriate local
   emergency authority may include, but is not limited to, an existing
   local law enforcement authority, such as the police, county sheriff,
   local emergency medical services provider, or fire department.

   Automated dispatchable location. Automatic generation of dispatchable
   location.

   Automatic Location Information (ALI). Information transmitted while
   providing E911 service that permits emergency service providers to
   identify the geographic location of the calling party.

   to be effectively available to a substantial portion of the public; or

   (2) The functional equivalent of such a mobile service described in
   paragraph (1) of this definition.

   (3) A variety of factors may be evaluated to make a determination
   whether the mobile service in question is the functional equivalent of
   a commercial mobile radio service, including: Consumer demand for the
   service to determine whether the service is closely substitutable for a
   commercial mobile radio service; whether changes in price for the
   service under examination, or for the comparable commercial mobile
   radio service, would prompt customers to change from one service to the
   other; and market research information identifying the targeted market
   for the service under review.

   (4) Unlicensed radio frequency devices under part 15 of this chapter
   are excluded from this definition of Commercial mobile radio service.

   the operational control of a single administrative authority.

   Person engaged in the business of installing an MLTS. A person that
   configures the MLTS or performs other tasks involved in getting the
   system ready to operate. These tasks may include, but are not limited
   to, establishing the dialing pattern for emergency calls, determining
   how calls will route to the Public Switched Telephone Network (PSTN),
   and determining where the MLTS will interface with the PSTN. These
   tasks are performed when the system is initially installed, but they
   may also be performed on a more or less regular basis by the MLTS
   operator as the communications needs of the enterprise change. The MLTS
   installer may be the MLTS manager or a third party acting on behalf of
   the manager.

   Person engaged in the business of managing an MLTS. The entity that is
   responsible for controlling and overseeing implementation of the MLTS
   after installation. These responsibilities include determining how

   responsible for the day-to-day operations of the MLTS.

   Pre-configured. An MLTS that comes equipped with hardware and/or
   software capable of establishing a setting that enables users to
   directly dial 911 as soon as the system is able to initiate calls to
   the public switched telephone network, so long as the MLTS is installed
   and operated properly. This does not preclude the inclusion of
   additional dialing patterns to reach 911. However, if the system is
   configured with these additional dialing patterns, they must be in
   addition to the default direct dialing pattern.

   Private mobile radio service. A mobile service that meets neither the
   paragraph (1) nor paragraph (2) in the definition of commercial mobile
   radio service in this section. A mobile service that does not meet
   paragraph (1) in the definition of commercial mobile radio service in
   this section is presumed to be a private mobile radio service. Private
   mobile radio service includes the following:

   (1) Not-for-profit land mobile radio and paging services that serve the
   licensee's internal communications needs as defined in part 90 of this
   chapter. Shared-use, cost-sharing, or cooperative arrangements,
   multiple licensed systems that use third party managers or users
   combining resources to meet compatible needs for specialized internal
   communications facilities in compliance with the safeguards of § 90.179
   of this chapter are presumptively private mobile radio services;

   (2) Mobile radio service offered to restricted classes of eligible

   this chapter).

   Pseudo Automatic Number Identification (Pseudo-ANI). A number,
   consisting of the same number of digits as ANI, that is not a North
   American Numbering Plan telephone directory number and may be used in
   place of an ANI to convey special meaning. The special meaning assigned
   to the pseudo-ANI is determined by agreements, as necessary, between
   the system originating the call, intermediate systems handling and
   routing the call, and the destination system.

   Public safety answering point or PSAP. An answering point that has been
   designated to receive 911 calls and route them to emergency services
   personnel.

   Public Switched Network. Any common carrier switched network, whether
   by wire or radio, including local exchange carriers, interexchange

   intended to go beyond, or has been beyond, the major portion of the
   Earth's atmosphere. (RR)

   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.

   Statewide default answering point. An emergency answering point
   designated by the State to receive 911 calls for either the entire
   State or those portions of the State not otherwise served by a local
   PSAP.

   Station. A station equipped to engage in radio communication or radio
   transmission of energy (47 U.S.C. 153(k)).

   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.”

   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.

   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.

   Wireline E911 Network. A dedicated wireline network that:

   (1) Is interconnected with but largely separate from the public
   switched telephone network;

   (2) Includes a selective router; and

   (3) Is used to route emergency calls and related information to PSAPs,
   designated statewide default answering points, appropriate local
   emergency authorities or other emergency answering points.
