Abstract
As disclosed, a two-way automatic communications system (TWACS) and method are used by an electrical utility in which outbound messages are sent from the utility to a consumer and inbound messages are sent from the consumer to the utility. The respective outbound and inbound messages are sent and received over the utility's power distribution system. A receiver including an analog filter component, an A/D converter and a digital processor detects the outbound messages. A substation transceiver is configured for sending analog outbound messages from the utility to a consumer. A transponder is configured for sending inbound messages to the transceiver from the consumer to the utility, the respective outbound and inbound messages being modulated on a mains signal of the utility's power distribution system. The receiver in another form includes an analog filter component, a detecting circuit and a demodulator.
