Abstract

Abstract There are disclosed automatic telephone dialing method and apparatus that can be commonly used in a plurality of countries for telephone-related devices such as telephone sets. According to the automatic telephone dialing method, control data for controlling various signals to be delivered to a circuit for placing a call are stored in a storage unit, and the signals are issued while their timing is controlled by the control data stored in the storage unit at the time of initiating a call. The automatic telephone dialing apparatus is composed of a storage unit for storing control data for controlling the timing of signals to be delivered to a circuit in initiating a call, an input unit for entering an address, a dialing signal issuing unit for issuing a dialing signal to the circuit, and a control unit for controlling the timing of delivery of the dialing signal according to the control data stored in the storage unit when issuing the dialing signal to the circuit through the dialing signal issuing unit and also for controlling the storage unit, the input unit, and the dialing signal issuing unit.
