Abstract
A method and apparatus for service multiplexing over telephone networks which employ bridged tap construction to allow the simultaneous delivery of different services to physically separated subscribers over a shared single pair of wires. Service is provided to one or more subscribers by connecting them to an open-circuited branch or directly with the working portion of the shared line. Service filters are used at appropriate locations in the network topology to couple or isolate the different communication channels. The wire pairs are used to simultaneously carry different services to physically separated subscribers, i.e., a portion of a common line carries one service to one location and a second service to another location. Telecommunication services are partitioned to occupy separate frequency bands in the spectrum of the transmission line using frequency division multiplexing (FDM) techniques. The location of the terminating point for each service is different and flexible as facilitated by the use of bridged taps, service drop connections and appropriate filtering. Inverse multiplexing, a method of combining multiple physical links (e.g., telephone lines) into a single, virtual communication link, is used to increase transmission bandwidth. The simultaneous delivery of different telecommunication services over a common line to physically separated subscribers may be used in conjunction with inverse multiplexing to increase and/or vary the transmission bandwidth to individual subscribers.
