Abstract
When an SP key is operated when power from a commercial utility is disconnected, an energized state forming circuit forms an energized state from a subscriber's line and power is supplied from the subscriber's power supply section through the energized state forming circuit to a microcomputer. The microcomputer thus is operated from the subscriber's line even after power failure occurs.
