Abstract

PURPOSE:To save the power and to increase the reliability, by stopping the dlivery of electromagnetic waves at waiting and performing the loop check for the control signal path. CONSTITUTION:The period of operation of the transmitter 22 of the wired terminal is controlled with the logic control circuit 30, and electromagnetic waves are stopped at waiting. Further, the mobile and wired terminals are provided with the detectors of 19 and 35 of the control signals f1 and f2, and a part of the receiver 12 is fed to the delivery signal switch 9 and that of the receiver 23 is fed to the delivery signal switch 27, and the loop check is performed by detecting that the control signal delivered by itself is returned to itself via the opposing unit. Further, the power supply to the receiver 12 is controlled with the logic control circuit 15, allowing to stop the operation at waiting.
