Abstract

PURPOSE: To inhibit the collection of the record information by the third caller and thus to prevent the leak of the privacy information by installing the transmitter and receiver circuit for the specific signals at the originating and incoming terminal units which are connected via the telephone exchange.
CONSTITUTION: The communication system comprises originating terminal unit 11, telephone exchange 12 and incoming terminal unit 13. Unit 11 contains telephone 14, dial pulse trunk circuit 15, switch circuit 16 which switches telephone circuit 22 to record information receiver 21 from circuit 15, and others. In addition, identification circuit 17 is provided to receive the connection confirmation signals via circuit 15 and 16 when exchange 12 is connected for identification, along with memory circuit 18, collation circuit 19, signal transmission circuit 20, facsimile receiver 21 and others. On the other hand, automatic response circuit 24 is installed to unit 13 to monitor the state of the caller's side, signal transmitter circuit 15 and 27, decision circuit 26, collation circuit 29 and others. Thus whether or not the reception signal is the prescribed audible frequency signal is collated and decided, and then facsimile transmission 30 is actuated.
