  • Multichannel telephone system
    Patent number: 4672657
    Abstract: A multi-channel RF telephone system that utilizes a dedicated channel status monitor to develop a list of available communications channels, and a common channel transceiver to transmit this list to the telephones. The telephones select a channel to use from this list by sequentially accessing the list a number of times based upon, at least in part, an identification number uniquely assigned to the telephone in question. If the selected channel is in fact unavailable, the telephone can update the list it maintains independently.
