§  90.473   Operation of internal transmitter control systems through
licensed fixed control points.

   An internal transmitter control system may be operated under the
   control and supervision of a control operator stationed at a fixed
   control point in the system. In such a case, the control point must be
   equipped to permit the control operator to monitor all traffic to and
   from fixed positions and mobile stations or paging units of the
   licensee; and the system shall be so designed to permit the control
   operator to either disconnect any operating position in the internal
   system from the transmitter control circuit or to close the system down
   entirely at will.
