PURPOSE:To obtain a power feeding controller for digital telephone set capable of saving power consumption. CONSTITUTION:A maintenance console 3 or a digital telephone set 2 is used to enter a power feeding stop time or restoration time to the digital telephone set 2 and registered in a power feeding information memory 10 in an exchange 1. A CPU 5 compares a registered time with a time signal from a clock circuit 11 and controls the power feeding to the digital telephone set 2 through a digital telephone set feeding control section 7 in response to the result of comparison. Thus, the power consumption is saved by registering the time so as to stop the power feeding when no digital telephone set is in use for night or the like. |
