Abstract

PURPOSE:To reduce the steady-state power consumption of the system by supplying a power supply to a line monitor circuit only when the line monitor is required. CONSTITUTION:When a terminal set 7 is not busy, P relay contacts 8a, 8b are turned to the position shown in figure and no power supply is given to a line monitor circuit 3. When the terminal set 7 is hooked off for talking, the off-hook information is fed to a radio utilization exchange 5 via a radio subscriber terminal equipment 6 and an antenna 9 and the information activates a relay 8. Then the contacts 8a, 8b are changed over and a power supply is supplied to the monitor circuit 3. The monitor circuit 3 is started by the power supply to monitor a DC voltage supplied from a subscriber circuit 1 to a speech line. When the termination of call of the subscriber is detected by the interruption of the DC voltage, the line monitor circuit 3 outputs a clear signal to be sent to the radio subscriber terminal equipment 6 from a dear terminal (CLR).
