High-speed data communication over a residential telephone wiring network
View Patent ↗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 within 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.
1. A communication hub for facilitating the communication of 100BaseT Ethernet signals and ordinary telephone signals across a junction where time 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.
2. The system of claim 1 further including a bypass path connecting one of said data ports with one of said data-over-voice ports, and a switch connected in series with said bypass path, said switch breaking the connectivity of said path at one setting, and having substantially no effect on the system when at a second setting.
3. The system of claim 1 wherein said 100BaseT Ethernet hub includes circuitry for pre-emphasis and amplification of Ethernet signals after they undergo conventional 802.11 Ethernet processing but before they exit from one of the ports of said hub.
4. The system of claim 1 wherein said 100BaseT Ethernet hub includes circuitry for amplification and equalization of Ethernet signals before they undergo conventional 802.11 Ethernet processing.
5. A communication hub for facilitating the communication of 10BaseT Ethernet signals and ordinary telephone signals across a junction where time 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 10BaseT 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 10BaseT Ethernet signals to flow through freely,
three low pass filters that block 10BaseT 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.
6. The system of claim 5 further including a bypass path connecting one of said data ports with one of said data-over-voice ports, and a switch connected in series with said bypass path, said switch breaking the connectivity of said path at one setting, and having substantially no effect on the system when at a second setting.
7. The system of claim 5 wherein said 10BaseT Ethernet hub includes circuitry for pre-emphasis and amplification of Ethernet signals after they undergo conventional 802.11 Ethernet processing but before they exit from one of the ports of said hub.
8. The system of claim 5 wherein said 10BaseT Ethernet hub includes circuitry for amplification and equalization of Ethernet signals before they undergo conventional 802.11 Ethernet processing.
