Abstract:
A system for increasing the capacity of preexisting subscriber lines located within a subscriber's premises comprising:at least two external analog telephone subscriber lines supplied by a telephone service provider including data, voice, and control signals;a master multiplexer subscriber line unit located external to said subscriber's premises comprising:at least two frontend electronic connections to said at least two external analog telephone subscriber lines supplied by the telephone service provider;multiplexing and demultiplexing circuitry for data voice communications for said at least two external analog telephone subscriber lines;detection and generation circuitry for analog telephone signaling and control;an interior preexisting conventional two conductor telephone wire;a slave demultiplexer subscriber line unit located within said subscriber's premises comprising:at least two output electronic connections for the generation of signals for two internal analog telephone subscriber lines for connection to analog terminal subscriber equipment;multiplexing and demultiplexing circuitry for data voice communications for said at least two internal analog telephone subscriber lines;AC power supply provided by said subscriber;detection and generation circuitry for analog telephone signaling and control, andwherein said at least two external analog telephone subscriber lines supplied by a telephone service provider are functionally connected to said analog terminal subscriber equipment through said master multiplexer, multiplexed across said interior preexisting conventional two conductor telephone wire, received by said slave multiplexer and connected to said at least two internal analog telephone subscriber lines thereby increasing the internal preexisting line capacity without physically adding additional lines internally.
