Abstract

PURPOSE:To eliminate the operation of the circuit change-over switch by carrying out the circuit switching via the hook switch which is operated by picking up and putting down the handset of the telephone and then simplifying the operation for talking. CONSTITUTION:When the handset is picked up at the originating side, the detection signal is supplied to control circuit 18 from hook-off detecting circuit 17. Circuit 18 delivers the coded information based on the detection signal. On the other hand, the supplied information is confirmed by circuit 18 at the incoming side, and buzzer circuit 9 and lamp circuit 10 are operated to inform the call request. Thus the detection signal of circuit 17 is supplied to circuit 18 when the handset is picked up at the incoming side. And then the circuit is switched to the talking side. Thus based on this switching, circuit 18 switches circuit change-over circuit 19. As a result, the circuit is switched to the talking from the communication to realize the talking.
