Abstract

PURPOSE:To attain redialing automatically at a prescribed interval by connecting a series comprising a recalling control circuit, an automatic restart circuit and an amplifier with speaker in parallel with a talking circuit. CONSTITUTION:In dialing a number while a handset is hooked off, the dialing of a called party is executed in a loop comprising an exchange 13, a telephone line connecting terminal 1, a hook switch 2, a dial circuit 3 and a talking circuit 4. When the called party is busy, the handset is hooked on andan automatic recalling switch 10 is depressed. In this case, the automatic restart circuit 8 is restarted at a prescribed interval and the dial number stored in a storage circuit 9 is dialed in a loop of the exchange 13, a recalling control circuit 7, the automatic restart circuit 8 and the dial number storage circuit 9. When the called party responds thereto, talking is executed by a loop comprising the exchange 13, the terminal 1, a hook switch 2, the dial circuit 3 and the talking circuit 4.
