Sec.  23.1   Definitions.

   Assigned  frequency.  The  frequency  coinciding with the center of an
   authorized bandwidth of emission.

   Authorized bandwidth. The maximum bandwidth authorized to be used by a
   station  as  specified  in the station license. This shall be occupied
   bandwidth or necessary bandwidth, whichever is greater.

   Authorized reference frequency. A frequency having a fixed and specific
   position with respect to the assigned frequency.

   Authorized  service. The term “authorized service” of a point-to-point
   radiotelegraph or radiotelephone station means the transmission of public
   correspondence to a point of communication as defined herein subject to such
   special provisions as may be contained in the license of the station or in
   accordance with  Sec. 23.53.

   Fixed  public  service.  The  term  “fixed  public  service”  means  a
   radiocommunication service carried on between fixed stations open to public
   correspondence.

   Fixed public press service. The term “fixed public press service” means a
   limited  radio communication service carried on between point-to-point
   telegraph stations, consisting of transmissions by fixed stations open to
   limited public correspondence, of news items, or other material related to
   or intended for publication by press agencies, newspapers, or for public
   dissemination. In addition, these transmissions may be directed to one or
   more fixed points specifically named in a station license, or to unnamed
   points in accordance with the provisions of  Sec. 23.53.

   Note:  This  section  is  not  intended  as  a definition of any press
   classification. Correspondence admissible under any press classification is
   determined by the tariffs of the various common carriers on file with the
   Commission.

   Fixed station. The term “fixed station” in the fixed public or fixed public
   press  service includes all apparatus used in rendering the authorized
   service at a particular location under a single instrument of authorization.

   Frequency  tolerance.  The maximum permissible departure by the center
   frequency of the frequency band occupied by an emission from the assigned
   frequency or by the carrier, or suppressed carrier, from the reference
   frequency.

   International fixed public radiocommunication service. A fixed service, the
   stations of which are open to public correspondence and which, in general,
   is intended to provide radiocommunication between any one of the contiguous
   48 states (including the District of Columbia) and the State of Alaska, or
   the State of Hawaii, or any U.S. possession or any foreign point; or between
   any U.S. possession and any other point; or between the State of Alaska and
   any other point; or between the State of Hawaii and any other point. In
   addition, radiocommunications within the contiguous 48 states (including the
   District of Columbia) in connection with the relaying of international
   traffic between stations which provide the above service, are also deemed to
   be the international fixed public radiocommunications service; provided,
   however,  that communications solely between Alaska, or any one of the
   contiguous 48 states (including the District of Columbia), and either Canada
   or  Mexico  are  not  deemed  to  be in the international fixed public
   radiocommunication service when such radiocommunications are transmitted on
   frequencies above 72 MHz.

   International fixed public control service. A fixed service carried on for
   the  purpose of communicating between transmitting stations, receiving
   stations, message centers or control points in the international fixed
   public radiocommunication service.

   Occupied bandwidth. The frequency bandwidth such that, below its lower and
   above its upper frequency limits, the mean powers radiated are each equal to
   0.5 percent of the total mean power radiated by a given emission.

   Point-to-point  telegraph  station. The term “point-to-point telegraph
   station” means a fixed station authorized for radiotelegraph communication.

   Point-to-point  telephone  station. The term “point-to-point telephone
   station” means a fixed station authorized for radiotelephone communication.

   Point of communication. The term “point of communication” means a specific
   location designated in the license to which a station is authorized to
   communicate for the transmission of public correspondence.

   Radiotelegraph. The term “radiotelegraph” as used in this part shall be
   construed to include types N0N, A1A, A2A, A3C, F1B, F2B, and F3C emission.

   Radiotelephone. The term “radiotelephone” as used in this part, with respect
   to   operation  on  frequencies  below  30  MHz,  means  a  system  of
   radiocommunication for the transmission of speech or, in some cases, other
   sounds by means of amplitude modulation including double sideband (A3E),
   single sideband (R3E, H3E, J3E) or independent sideband (B3E) transmission.
