Abstract

PURPOSE:To eliminate the need for changing-over operation at a telephone set at the time of a computer service is received by changing over automatically from a dial pulse to an MF signal when an opponent responds. CONSTITUTION:When sending is executed from a telephone set 7 and an opponent responds, a response detecting circuit 2 detects the inversion of the voltage of a telephone line 1 and communicates to a CPU 8 that the opponent responds. Thereafter, when dialing is executed by the telephone set 7, the dialing information through a telephone set interface circuit 6 is communicated to the CPU 8 and a calling path 4 is changed over to an MF signal sending circuit 5 by the control of the CPU 8. After an MF signal is sent from the circuit 5, the CPU 8 controls the calling path 4, changes over and connects it to the circuit 6.
