A predetermined DC voltage is applied to the line to close it, and in response to the caller's hook-on operation, the call line is temporarily disconnected, and at the same time, a termination signal such as a busy tone is sent to the called party. In a type of telephone switching system, a device connected to the called party side of the telephone line, which passes the ringing signal received via the line extending from the exchange to the called party side, and a capacitor that supplies a light emitting section of the photocoupler to generate a predetermined light emission output; and an output of the light receiving section of the photocoupler is connected to a set side input, so that the capacitor is set in response to the light emission output. When this flip-flop is set, a hook-off operation is performed to close the line between the line transformer for terminating the line and the exchange, and at the same time, the output of the light receiving section of the photocoupler is a control circuit that switches the voltage to be applied to the reset side input of the flip-flop; and the hook-off operation of the control circuit stops the light emission output of the light emitting section of the photocoupler and maintains a constant DC voltage at a predetermined DC voltage applied to the line. by charging the capacitor to accumulate a charge of
and a rectifier circuit that discharges the accumulated charge in the capacitor to the light emitting section of the photocoupler so that a predetermined light emission output is generated.
