ABSTRACT:
A communication system which controls access to a single communications channel by a plurality of remote units arranged in predetermined groups is disclosed. Assignment of the channel is controlled by a central control station which provides time periods on the channel for remote units to request permission to transmit on the channel. As the channel becomes clear, the central control station transmits a grant of service to a requesting remote unit group permitting real time transmission of voice or data on the channel. At the conclusion of the transmission, the central control station detects an end-of-transmission condition and revokes the grant of service to the served remote unit group.
