Title: Monitoring system for digital communication channel
Inventor: ICHIKAWA TAKAAKI
IPC: H04J3/14
Filed: 1989-06-05
Abstract: PURPOSE:To prevent a malfunction by providing a 3rd line monitoring means detecting the bit error of the entire communication channel at a reception terminal station and a means raising a line deterioration alarm with ORing signals representing faults being the result of detection of 1st-3rd line monitoring means. CONSTITUTION:A deterioration detection circuit 47 detects a bit error rate between terminal stations and sends an output when the error rate exceeds a prescribed threshold level. The detection output is faulty from its occurrence time t1 when the disconnection of the line takes place on the midway section and the faulty state is consecutive till the time when the fault is recovered. Then even when a frame synchronization fault is not detected for a short time between times t1 and t2, the detection output of the deterioration detection circuit 37 compensates it and an alarming output from an OR circuit 38 is sent consecutively. Thus, even when the line is switched by the OR circuit 38, misrecognition that a line is recovered due to interrupted alarm output caused by a delay in the fault detection of the frame synchronization does not take place.
