ABSTRACT:
In a communication apparatus in which a first level unit, a second level unit and a third level unit are hierarchically arranged and these units are connected to one another by multicore cables, one of the many cores of each multicore cable is used as monitoring core, and the first level unit sends out to each monitoring core a probe signal generated by sampling the digital signals supplied via the individual cores of the multicore cable and multiplexing them on a time-division basis. The second level unit compares each of these probe signals and a string of signal samples supplied via the multicore cable corresponding to this probe signal, generates a faulty connection indicating signal in response to any discrepancy between them; generates, similarly to the first level unit, a probe signal for detecting any faulty connection between the second level and third level units; multiplexes these signals on a time-division basis; and inserts the multiplexed signal into the monitoring core to the third level unit. The third level unit, on the basis of the probe signal for this signal supplied via the monitoring core, can display a faulty connection signal both for each multicore cable and for each individual core.
