Abstract

PURPOSE:To increase the reliability of the control system and to make light the wired terminal unit in weight and to simplify it, for the exclusive unit of outgoing call, by generating the control signal only to the mobile terminal unit. CONSTITUTION:The period of operation of the transmitter 22 is conrolled with the logic control circuit 30, the detector 19 stopping electromagnetic waves at waiting and detecting the control signal f1 developed by itself to the mobile terminal is provided, and the control signal f1 returned via the wired terminal by feeding a part of the output of the receiver 12 is detected, allowing to perform loop check.
