Abstract
The present invention provides a system and method for using existing wiring or cabling in a residence or other customer premises both (a) to transmit network telecommunications to a gateway or similar device for processing, and (b) to distribute processed signals from the device to video, telephony and data receivers. The invention enables and facilitates the receipt by telephone company subscribers of high-speed digital telecommunications over twisted-wire pair cabling historically installed and used for voice telephone service. In an embodiment, the system of the present invention comprises a bidirectional transmission facility, a first diplexer, and a second diplexer; the first diplexer receives network signals and transmits them or passes them on, using the bidirectioal transmission facility, to the second diplexer; and the second diplexer receives distribution signals and transmits them or passes them on, using the bidirectional transmission medium, to the first diplexer.
