Sec.  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 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.

   Home Carrier . For automatic roaming, a home carrier is the facilities-based
   CMRS carrier with which a subscriber has a direct contractual relationship.
   A home carrier may request automatic roaming service from a host carrier on
   behalf of its subscribers.

   Home Market . For automatic roaming, a CMRS carrier's home market is defined
   as any geographic location where the home carrier has a wireless license or
   spectrum usage rights that could be used to provide CMRS.

   Host Carrier . For automatic roaming, the host carrier is a facilities-based
   CMRS  carrier on whose system a subscriber roams when outside its home
   carrier's home market.

   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   Sec. 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.
