Patent ID: 7702095

Claim:
A network for carrying analog telephone, power and data signals, the network comprising: a single wire pair concurrently carrying a DC power signal, an analog telephone signal and a bi-directional digital data signal, wherein the analog telephone signal and the bi-directional digital data signal are carried using frequency division multiplexing, with the digital data signal being carried in a digital data signal frequency band and the analog telephone signal being carried in an analog telephone signal frequency band lower than the digital data signal frequency band; a central office-side unit connected to said single wire pair for coupling a central office-side telephone signal to the analog telephone signal, for converting a power source signal to the DC power signal, and for coupling a data network to the bi-directional digital data signal; and a subscriber-side unit connected to said single wire pair, said subscriber-side unit comprising: a telephone connector connectable to an analog telephone set for coupling the analog telephone set to the analog telephone signal, and a data port couplable to a data unit for coupling the data unit to the bi-directional digital data signal, wherein the subscriber-side unit is at least in part powered by the DC power signal.
