  • Distributed telephone system
    Patent number: 4757496
    Abstract: A communication system is provided for the interconnection of telephones and other instruments capable of communicating via the voice spectrum, the system providing a single transmission line such as a coaxial cable by which full duplex communication is provided between any pair of telephones. Each instrument is coupled to the transmission line by a control unit which includes computer operated transceiver equipment for paging other ones of the control units to initiate a telephonic communication. Each control unit is provided with an identification number and circuitry for recognizing the identification number contained within a paging signal so as to initiate a response. In a separate spectral portion of the transmission line, there are provided sets of analog communication channels each of which has upper and lower spectral portions to provide two-way communication in opposite directions between a pair of telephones engaged in communication.
