Abstract:
A system for data communication over an active telephone wiring network, which includes a first segment coupling a telephone exchange and a residence and a second portion forming a network within the residence, and over which voice signals pass in a voice band of frequencies between the telephone exchange and one or more telephones coupled to the second portion of the wiring network, the system comprising:a first communication module at a first location on the telephone wiring network including a first port for coupling to the telephone wiring network and providing a communication path in a first data band of frequencies above the voice band between the communication module and the telephone exchange over the telephone wiring network, a second port for passing data signals in the first data band between the first communication module and a modem, circuitry for passing signals in the first data band between the first port and the second port, a plurality of ports for coupling to a data hub and passing data signals in a second data band of frequencies above the first data band between the first communication module and the data hub, and circuitry for passing signals in the second data band between the telephone wiring network and one of the plurality of ports for coupling to the data hub; a second communication module at a second location on the telephone wiring network including a first port for coupling to the telephone wiring network and providing a communication path in the second data band between the first communication module and the second communication module over the telephone wiring network, a second port for passing signals in the second data band from the second communication module to a computer at the second location, and circuitry for passing signals in the second data band between the first port and the second port; a first hub coupled to the first communication module; a modem coupled between the first hub and the second port of the first communication module, wherein the modem bridges data communication in the first data band and data communication in the second data band; and a second hub coupled between the second communication module and the computer at the second location; wherein the second communication module includes a third port for coupling to the second hub, a fourth port for coupling to a branch of the wiring network, circuitry for passing signals in the second data band between the third port and the fourth port, and circuitry for passing signals in the voice band between the first port and the fourth port; and wherein the system provides a data communication channel passing between the computer at the second location and the telephone exchange and said data communication channel passes over the telephone wiring network in the second data band between the second communication module and the first communication module, passes between the first communication module and the modem through the first hub, and passes between the modem and the telephone exchange over the wiring network in the first data band.
