§ 90.465   Control of systems of communication.

   (a) Depending on design considerations, control of a system of
   communication may be exercised in varying ways. In single frequency
   simplex, base/mobile operations, control may be exercised by the
   control operator at the fixed control point. In mobile relay systems,
   where there is an associated control point or control station, control
   may be exercised by the operator at the control point or control
   station. In mobile-only systems, control may be exercised by the mobile
   operator. In communication systems involving multiple base stations or
   fixed relays control of the system may result from a combination of
   factors and considerations, including control by a fixed control point
   operator at some point within the system of communication or control by
   the mobile station operator of the licensee.

   (b) In internal systems, as defined in § 90.7, control may be
   maintained by conforming the system to the requirements of § § 90.471
   through 90.475.

   (c) In interconnected systems, as defined in § 90.7, control may be
   maintained by conforming operation and system design to that permitted
   in § § 90.477 through 90.483.
