Abstract

PURPOSE:To call a destination station even in case of the occurrence of power failure by providing a means which switches the control to directly control a select signal transmission equipment by a dialing equipment or control this equipment through a control means. CONSTITUTION:A call originating equipment 3 is operated by the line current of a line 9. A call originating equipment 4 is operated by the electromotive force of the power supply part of the device. In case of the occurrence of a power failure, direct dialing is possible by the call originating equipment 3. Switching between the use of the equipment 3 and the use of the equipment 4 is controlled by a hook switch 7. Consequently, a handset is hooked off to perform dialing if a CPU 1, the call originating equipment 4, and the other circuits cannot be operated because of the occurrence of a power failure or the like, thereby calling the destination station.
