A self-diagnostic system for a checking all functions of a cellular-transceiver system having a cellular-interface unit, which interface unit couples a standard telephone set to a cellular transceiver, which interface unit converts the DTMF or pulse-type of dialing signals into digital format for transmission to the cellular transceiver, whereby the dialed number made on the land-type of telephone may be used to call a number over the cellular system. The present invention not only monitors and checks the proper functioning of the transceiver and associated power supply, and the like, but will also monitor and check the interface unit, and report the results to an off-site monitoring center by means of the cellular network.
In an apparatus for testing the proper functioning of a cellular, or cellular-like, transceiver and a cellular, or cellular-like, interface unit operatively coupled to said cellular transceiver, said apparatus comprising a cellular, or cellular-like, transceiver and a cellular, or cellular-like, interface unit operatively coupled to said cellular transceiver, and a land-type telephone device directly coupled to said cellular, or cellular-like, interface unit, said interface unit coupling said land-type telephone device to said cellular, or cellular-like, transceiver, whereby said land-type telephone device is coupled for use with the cellular, or cellular-like, system, the improvement comprising:
A method of remotely testing for the proper operation of a cellular, or cellular-like, interface unit by means of a diagnostic unit, which cellular, or cellular-like, interface unit is capable of being coupled to a land-type telephone or telephone-like instrument, said method comprising:
