Abstract

PURPOSE:To detect abnormality of a transmission/reception system by switching alternately for each frame 1st transmission/reception system and 2nd transmission/reception system to send a signal from a base station to a slave station, thereby monitoring the response from the slave station. CONSTITUTION:The transmission output of the 1st transmission/reception system 21 and the 2nd transmission/reception system 22 is switched by a changeover switch at each frame, sent alternately to a slave station from a base station and a reply signal in response to an outgoing signal from each slave station comes to the base station with a delay of one frame period. If any error takes place in the time slot period when the 2nd transmission/reception system transmits, the reply from the slave station 53 assingned with the time slot T2 is missing or normal reply signal (b) does not arrive. Thus, the base station 1 identifies the occurrence of a fault anywhere in the path of transmission/ reception system 22 slave station 52 transmission/reception system 22.
