Abstract
A method and system for distributing multimedia signals to a subscriber from a headend unit using a tap. The multimedia signals are transmitted on a network media as a composite RF and AC signal. A tap is upgraded by with a circuit that separates the AC from the RF signal in the composite signal. The separated AC signal is split in the upgraded tap. The RF signals are split in a circuit on the faceplate of the tap. The AC signal is fed to a power distribution unit which generates an AC output signal that is surge protected, RF filtered and current limited. The split RF signal and AC output signals are fed to connectors on the faceplate. By providing a tap where the AC and RF signal are separated in the same unit, the system can be upgraded with a power distribution unit when AC signals are required to supply power to subscriber equipment.
