Abstract:
A system for communicating information between an external source of information and destinations of information each at a different one of a plurality of residences over a telephone wiring network used for passing telephone signals in a telephone voice band between telephone devices at the residences and a telephone exchange, comprising:a plurality of transceivers, each located at a different one of the residences and coupled to a destination of information at said residence; a signal interface located on the telephone wiring network between the telephone exchange and each of the residences; a plurality of separate conductive paths, each coupling the signal interface and a different one of the plurality of transceivers and providing at least part of a path for telephone signals in the voice band between the telephone exchange and one or more of the telephone devices at the same residence as said transceiver, wherein each of said separate conductive paths exceeds 1000 feet in length; at each of the residences at which one of the transceivers is located, a branch conductive path coupled at a location separated from said transceiver to the separate conductive path from the signal interface to said transceiver, said branch conductive path providing at least part of the path for telephone signals in the voice band between the telephone exchange and a telephone device at said residence; and for each branch conductive path, a filter coupled between the branch conductive path and the corresponding telephone device; wherein each transceiver includes circuitry for communicating with the signal interface in a high frequency band of frequencies above the highest frequency of the telephone voice band over the separate conductive path coupling said transceiver with the signal interface; each of the filters that is coupled to a branch conductive path is configured for preventing signals in the high band of frequencies from passing to the telephone device coupled to said branch conductive path; and the signal interface includes circuitry for receiving a plurality of external signals encoding information streams from the external source of information, circuitry for transmitting over the telephone wiring network to the transceivers a plurality of internal signals in the high frequency band encoding the information streams, and circuitry for limiting transmission of signals in the high frequency band from the telephone wiring network to the telephone exchange and for passing signals in the telephone frequency band between the telephone wiring network and the telephone exchange.
