A method and system for distributing multimedia signals to a subscriber from a headend unit. The multimedia signals are transmitted on a network media as a composite RF and AC signal. A passive unit is upgraded by with a circuit having connectors that separates the AC from the RF signal. The signals are split in the upgraded passive unit. 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 RF signal and AC output signal are separately fed to a customer interface unit where the RF signal is decoded and transmitted to a subscriber. By providing a passive unit 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. |
