The present invention is generally directed to a system and associated
method for communicating information to a predetermined location. 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 A portion of the information signal includes an
instruction code, which may be decoded by the central station and acted
upon accordingly Consistent with the general purpose nature of the
transceiver, the phone number of the central station may be transmitted
to the transceiver as part of the information signal.
