Abstract: PURPOSE:To simplify a circuit and to switch efficiently a telephone circuit by switching a holding tone signal from a holding tone source and a generation signal from a DTMF signal generator circuit and transmitting them to a telephone circuit through a transmission circuit. CONSTITUTION:When a telephone circuit 1' is held, a holding tone signal from a holding tone source 5 is transmitted to the telephone circuit 1' side through a gate circuit 6, and a relay contact point rl21 operates. Consequently the holding tone signal is transmitted to the circuit 1' through a transformer T21, capacitor C21 and the relay contact point rl21. Moreover, a holding signal with respect to a telephone circuit 2' is transmitted to the circuit 2' in the same manner. When dialing is executed with respect to the circuit 1', a DTME signal generated in a DTMF signal generator circuit 4 is transmitted to the circuit 1' side through the circuit 6 and then transmitted to the circuit 1' side through the transformer T21, capacitor C21 and relay contact point rl21. The dialing is executed with respect to the circuit 2'. Thus the DTMF signal generator circuit can be shared, and a single signal transmission circuit can be sufficient, thereby simplifying the circuit.
