ABSTRACT:
An automated electric power distribution network includes a radio communication system for transmitting multipurpose, multitone signals in one or more signaling channels over the auxiliary channel or channels of one or more commercial broadcast stations. Energy management terminals receive the signals at remote locations served by the distribution network. Radio receivers at the terminals have frequency selective detectors responsive to different multitone signals. The selective allocation of the multitone signals at different remote locations provides different communication links for effecting common or different electric energy usage related responses at grouped or separate locations. Complex address and/or function encoded signal information is reduced by providing the frequency selective reception of the several multitone signaling channels available in a radio or television station auxiliary channel.
