Abstract

PURPOSE:To omit a telephone message transfer by responding automatically a call signal from amain trunk, receiving a selecting signal by a called party, and generating a call tone corresponding to the called party so as to discriminate the called party by means of the call tone. CONSTITUTION:The call signal inputted from a main trunk connecting terminal 1 is received by a call signal receiving section 3 and the call tone is generated from a telephone basic function section 2. Further, the call signal is applied to a control section 9 and when the call signal is received for a prescribed time, the control section 9 activates a main trunk connecting section 4, a DC loop is formed with the main trunk to form the communicating state. Then, a message who is to be called is transmitted from a response section 5, a caller receiving it depresses a push button of the function section 2 to transmit a predetermined selecting signal by called party. A selection signal detecting section 6 receives it, a call tone having a sound tone corresponding to the selecting signal is selected by a sound source section 7 via the control section 9 to ring an electroacoustic transducer section 8. A called party listening to it hooks on a handset of the function section 2, the control section 9 stops the ring of the call tone.
