Abstract
A plurality of communication stations is interconnected by conductors. Each station includes a transmitter and a receiver as well as control means. The transmitters transmit on any of several frequency bands, each such band being assigned to the receiver of a remote station. A signal generator interconnects the stations and generates intervalled pulse trains upon which the control means of the stations operate to impress coded control pulses. The stations include novel phase locking and phase detecting circuits.
