§  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.
