Patent ID: 8107618

Claim:
A device for use with a wire pair connected for simultaneously carrying a power signal at a power signal frequency, the power signal having a higher power level than a DC telephone signal, and a bi-directional packet-based digital data signal in a digital data frequency band at least in part above an analog telephone frequency band and above the power signal frequency, said device being operative to couple the bi-directional packet-based digital data signal to a data unit, said device comprising: a wiring connector for connecting to the wire pair; a high pass filter coupled to said wiring connector for passing signals in the digital data frequency band; a modem coupled to said high pass filter for transmitting the bi-directional packet-based digital data signal to, and receiving the bi-directional packet-based digital data signal from, the wire pair; a bi-directional packet-based digital data port couplable to the data unit for coupling the bi-directional packet-based digital data signal to the data unit; and a single enclosure housing said wiring connector, said high pass filter, said modem, and said digital data port, wherein the modem is coupled to said wiring connector to be powered from the power signal.
