Abstract: A combined power and communication delivery system for installation at or beyond the demarcation point in a residential or business building is described. The system has a power input module and a plurality of traditional voice and data communication wires, one pair of the wires being an unused voice or data communication line and being connected to the power input module thereby making the one pair a current-carrying line, and the plurality of wires terminating at at least one female multi-wire telephone jack. The system further having at least one power-communication cable, having a first end being a male multi-wire plug to releasably engage the female multi-wire telephone jack, a second end partially depending from the first end carrying one or more voice and data communication transmission lines, and a third end partially depending from the first end to transmit current from the current-carrying line.
