Abstract
A method and system for communicating between a number of computers within a residence over an active telephone network, and for communicating data between a telephone exchange and the residence in a first data band concurrently with the computers communicating in a second data band over the telephone wiring network with the residence. A modem bridges communication in the first data band and the second data band enabling the computers to communicate with the telephone exchange, which may provide a data path to other computers, for instance over the Internet. In addition, signals such as video signals can be distributed within the residence in an additional high-frequency band making use of common circuitry for both data and video communication.
Claims4
A communication hub (710) for facilitating the communication of 100BaseT Ethernet signals and ordinary telephone signals across a junction where three conductive paths, each composed of two twisted wires, join together, the hub comprising:
- three data-over-voice ports each of which connects to one of said conductive paths,
- three data ports, each of which connects to a port on a 100BaseT Ethernet hub via a path consisting of two twisted pair wires,
- three high pass filters that block ordinary telephone signals on each of two twisted pair paths but allow 100BaseT Ethernet signals to flow through freely,
- three low pass filters that block 100BaseT signals on each of two twisted pair paths but allow ordinary telephone signals to pass freely,
- one voice port for connection of one or two telephone devices,
- wherein,
- each high pass filter connects between a different one of said data-over-voice ports and a different one of said data ports, and
- each low pass filter connects between a different one of said data-over-voice ports and said voice port,
