  §  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 § 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
   § 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.
