Abstract

PURPOSE:To make it possible to prevent an error connection due to malfunction, etc., of a dial by coupling a magnetic card, on which a connection-established number is previously stored, with a connection-established number read circuit and by sending the connection number to an exchange automatically. CONSTITUTION:After a dial tone is confirmed by a receiver, magnetic card 11 with a previously-stored connection-established number is coupled with connection- established number read circuit 7. This read circuit 7 reads memory contents out of magnetic card 11 and then stores them in memory circuit 8. The connection-established number stored in memory circuit 8 is sent to sending circuit 8. This sending circuit 9 converts the signal from circuit 8 into a fixed dial signal, which is transmitted to switching control part 10. This control part 10 exercises switching control over the signal from sending circuit 9 and that from dial signal sending mechanism part 2. Under the switching control, the connection number from sending circuit 9 is sent out to telephone-set network 3 and then led to exchange 5 via communication line 4.
