§ 90.461   Direct and remote control of transmitters.

   (a) In general. Radio transmitters may be operated and controlled directly
   (as when the operating position for the transmitter and the transmitter
   being  operated  are  at  the same location), or remotely (as when the
   transmitter being operated and the position from which it is being operated
   are at different locations).

   (b) Control of transmitters at remote locations. Radio transmitters at
   remote locations may be operated and controlled through the use of wire line
   or radio links; or through dial-up circuits, as provided in paragraph (c) of
   this section. Such control links or circuits may be either those of the
   licensee or they may be provided by common carriers authorized by law to
   furnish such service.

   (c)  Dial-up  circuits.  Dial-up circuits may be provided by wire line
   telephone companies under appropriate tariffs, and they may be used by
   licensees for purposes of transmitter control, provided:

   (1) The dial-up circuits serve only to link licensed transmitter control
   points and the transmitters being controlled.

   (2)  The  dial-up circuits are so designed that the transmitters being
   controlled  cannot  be operated from any fixed position other than the
   licensed control points for those transmitters.

   (3) Equipment used to provide the transmitter/dial-up-circuit interface is
   designed to preclude associated mobile units of the licensee from reaching
   any point(s) served by the wire line telephone facilities other than the
   control point(s) of the station(s) controlled.

   (4) Any direct electrical connection to the telephone network shall comply
   with applicable tariffs and with part 68 of the Commission's Rules (See
   § 90.5(j)).

   (5) Interconnection, within the meaning of § § 90.7 and 90.477 through 90.483,
   may not take place at a control point which connects to its associated
   transmitter(s) through dial-up circuits; nor may such dial-up transmitter
   control circuits be used in conjunction with (or shared by) interconnection
   equipment.
