PURPOSE:To confirm the equipment which is operating, by changing the response signal according to current and stand-by radio equipments in case that the false response signal is returned for the test signal from the master station of the radio telephone system from the terminal station having current and stand-by radio equipments. CONSTITUTION:On the assumption that the current equipment is operating in terminal station 21 and the stand-by equipment is operating in terminal station 22 and the current equipment is operating in terminal station 2n. When terminal stations 21-2n receive test signal 4 from master station 1, current equipment operating signal A is transmitted from terminal 21 as false response signal 5, and stand-by equipment operating signal B is transmitted from terminal station 22 as false response signal 5 with a delay. Then, current equipment operating signal A is transmitted from terminal station 2. False response signals from terminal stations 21-2n are monitored by master station 1 to grasp operating equipments of terminal station radio equipments simultaneously with the line test. |
