Abstract
A tap for delivering electrical power and video signals to subscriber substations includes an input coupling module for coupling a main video signal and a main power signal from a cable conductor to the tap. Means are provided for generating a subscriber video signal and a subscriber power signal by extracting portions of the signals from the main cable. The subscriber video signals and subscriber power signals then are transmitted to subscriber substations. Communication devices in the subscriber substations can be powered by the subscriber power signal in the absence of electrical power from a power utility.
