Patent ID: 7145990

Claim:
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.
