Abstract

PURPOSE:To relieve the load of a power supply, power consumption and heat by avoiding power supply to circuits other than a power supply control circuit in an outgoing trunk and to circuits other than a power supply control circuit and a start signal detection circuit in an incoming trunk while no call exists. CONSTITUTION:A power supply control circuit 4 of an outgoing trunk 3 starts or stops the power supply from a power supply 6 according to a signal from a power supply command circuit 2 of a trunk controller 1. When a host device detects the end of a call, the power supply command circuit 2 of the trunk controller 1 outputs a signal to stop the power supply to the outgoing trunk 3 to the power supply control circuit 4. when the power supply control circuit 4 receives the signal, the power supply from the power supply 5 to the outgoing trunk 3 is stopped. Thus, load of power supply, power consumption and heat are relieved.
