§  20.3   Definitions.

   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.

   Automatic Number Identification (ANI). A system that identifies the
   billing account for a call. For 911 systems, the ANI identifies the
   calling party and may be used as a call back number.

   Automatic Roaming . With automatic roaming, under a pre-existing
   contractual agreement between a subscriber's home carrier and a host
   carrier, a roaming subscriber is able to originate or terminate a call
   in the host carrier's service area without taking any special actions.

   Commercial mobile data service. (1) Any mobile data service that is not
   interconnected with the public switched network and is:

   (i) Provided for profit; and

   (ii) Available to the public or to such classes of eligible users as to
   be effectively available to the public.

   (2) Commercial mobile data service includes services provided by Mobile
   Satellite Services and Ancillary Terrestrial Component providers to the
   extent the services provided meet this definition.

   Commercial mobile radio service. A mobile service that is:

   (a)(1) provided for profit, i.e. , with the intent of receiving
   compensation or monetary gain;

   (2) An interconnected service; and

   (3) Available to the public, or to such classes of eligible users as to
   be effectively available to a substantial portion of the public; or

   (b) The functional equivalent of such a mobile service described in
   paragraph (a) of this section.

   Designated PSAP. The Public Safety Answering Point (PSAP) designated by
   the local or state entity that has the authority and responsibility to
   designate the PSAP to receive wireless 911 calls.

   Incumbent Wide Area SMR Licensees. Licensees who have obtained extended
   implementation authorizations in the 800 MHz or 900 MHz service, either
   by waiver or under Section 90.629 of these rules, and who offer
   real-time, two-way voice service that is interconnected with the public
   switched network.

   Handset-based location technology. A method of providing the location
   of wireless 911 callers that requires the use of special
   location-determining hardware and/or software in a portable or mobile
   phone. Handset-based location technology may also employ additional
   location-determining hardware and/or software in the CMRS network
   and/or another fixed infrastructure.

   Host Carrier. For automatic roaming, the host carrier is a
   facilities-based CMRS carrier on whose system another carrier's
   subscriber roams. A facilities-based CMRS carrier may, on behalf of its
   subscribers, request automatic roaming service from a host carrier.

   Interconnection or Interconnected. Direct or indirect connection
   through automatic or manual means (by wire, microwave, or other
   technologies such as store and forward) to permit the transmission or
   reception of messages or signals to or from points in the public
   switched network.

   Interconnected Service. A service:

   (a) That is interconnected with the public switched network, or
   interconnected with the public switched network through an
   interconnected service provider, that gives subscribers the capability
   to communicate to or receive communication from all other users on the
   public switched network; or

   (b) For which a request for such interconnection is pending pursuant to
   section 332(c)(1)(B) of the Communications Act, 47 U.S.C. 332(c)(1)(B).
   A mobile service offers interconnected service even if the service
   allows subscribers to access the public switched network only during
   specified hours of the day, or if the service provides general access
   to points on the public switched network but also restricts access in
   certain limited ways. Interconnected service does not include any
   interface between a licensee's facilities and the public switched
   network exclusively for a licensee's internal control purposes.

   Location-capable handsets. Portable or mobile phones that contain
   special location-determining hardware and/or software, which is used by
   a licensee to locate 911 calls.

   Manual Roaming . With manual roaming, a subscriber must establish a
   relationship with the host carrier on whose system he or she wants to
   roam in order to make a call. Typically, the roaming subscriber
   accomplishes this in the course of attempting to originate a call by
   giving a valid credit card number to the carrier providing the roaming
   service.

   Mobile Service. A radio communication service carried on between mobile
   stations or receivers and land stations, and by mobile stations
   communicating among themselves, and includes:

   (a) Both one-way and two-way radio communications services;

   (b) A mobile service which provides a regularly interacting group of
   base, mobile, portable, and associated control and relay stations
   (whether licensed on an individual, cooperative, or multiple basis) for
   private one-way or two-way land mobile radio communications by eligible
   users over designated areas of operation; and

   (c) Any service for which a license is required in a personal
   communications service under part 24 of this chapter.

   Network-based Location Technology. A method of providing the location
   of wireless 911 callers that employs hardware and/or software in the
   CMRS network and/or another fixed infrastructure, and does not require
   the use of special location-determining hardware and/or software in the
   caller's portable or mobile phone.

   Private Mobile Radio Service. A mobile service that is neither a
   commercial mobile radio service nor the functional equivalent of a
   service that meets the definition of commercial mobile radio service.
   Private mobile radio service includes the following:

   (a) 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;

   (b) Mobile radio service offered to restricted classes of eligible
   users. This includes entities eligible in the Public Safety Radio Pool
   and Radiolocation service.

   (c) 220-222 MHz land mobile service and Automatic Vehicle Monitoring
   systems (part 90 of this chapter) that do not offer interconnected
   service or that are not-for-profit; and

   (d) Personal Radio Services under part 95 of this chapter (General
   Mobile Services, Radio Control Radio Services, and Citizens Band Radio
   Services); Maritime Service Stations (excluding Public Coast stations)
   (part 80 of this chapter); and Aviation Service Stations (part 87 of
   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. A point that has been designated to
   receive 911 calls and route them to emergency service personnel.

   Public Switched Network. Any common carrier switched network, whether
   by wire or radio, including local exchange carriers, interexchange
   carriers, and mobile service providers, that use the North American
   Numbering Plan in connection with the provision of switched services.

   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.
