摘要：PURPOSE:To cure an automatic performance of various types of rvices as the subscriber desires by controlling the outgoing/incoming for the individual carrying the transmitter with him via the controller or the exchange and thus varying the functions of the telephone and the exchange. CONSTITUTION:Transmitter 9 carried by each individual transmits the electric waves or the ultrasonic waves which are modulated by the individual-bad code or frequency. And at the side of receiver 7, the waves or the ultrasonic waves are received within each telephone 13 to perform the demodulation. Then receiver 7 informs exchange 3 via the subscriber line of controller 8 or telephone 13 the fact that the individual carrying the transmitter is near telephone 13, and then the outgoing/incoming regarding the individual carrying transmitter 9 is controlled via controller 8 or exchange 3. Thus, the functions can be altered for telephone 13 or exchange 3, and ensuring an automatic execution for various types of rvices according to the subscriber's desire.
