Abstract

PURPOSE:To reduce power consumption by starting power supply to a dial pulse controlling circuit only when a subscriber's key input or hook off is detected by a microcomputer and stopping power source supply after completion of control of the controlling circuit. CONSTITUTION:A microcomputer 3 is always in the state of operation. However, the power source of a dial pulse controlling circuit 2 is cut off. The microcomputer 3 detects hook off and detects that a telephone set is used. When a dial key is depressed by a keyboard, etc., the microcomputer 3 sends out an HS signal to the dial pulse controlling circuit 2. On receiving the HS signal, the power source is applied to the controlling circuit 2 and the circuit becomes the state of operation. After sending out of the dial pulse, the microcomputer 3 is informed of completion of sending out of the dial by disappearance of a mute signal, and makes the controlling circuit 2 to the state of non-operation.
