发明名称 DISTRIBUTED SWITCHING TELECOMMUNICATIONS SYSTEM
摘要 A system that interconnects several units such as telephones to a transmission media such as a coaxial cable (11, 12). An interface (20) between the cable and the phones, divides the cable into channels and interconnects the phones to the different channels. This Distributed Switching System (DSS) for phones eliminates the need for the long pair of wires and the central switch in a telephone system.
