The system includes a transmitter disposed at a first location and configured to transmit a signal containing an instruction code that uniquely identifies an instruction to be carried out. The system further includes a transceiver disposed remotely from the transmitter and configured to receive the transmitted signal. The transceiver circuit includes a line interface circuit configured to interface with a telephone line that is part of the public switched telephone network (PSTN) and initiate a phone call over the telephone line. Finally, the system includes a central station remotely located from said transceiver but being in communication with said transceiver via the PSTN. The central station further include a decoder configured to decode the instruction code. In accordance with a broader aspect, the invention is directed to a general purpose transceiver having a receiver for receiving an information signal and a transmitter configured to transmit an outgoing signal over a phone line to a central station.
