Abstract
Stations of a communications network maintain a set of counters which measure the frequency of occurrence of soft errors in said network. Periodically, each station generates and transmits an error report containing the error counts to a ring error monitor provided in one of the stations. The ring error monitor analyzes the report and calculates and stores weighted error counts for stations in an error domain. The stored error counts are integrated, over a selected time interval, and compared with a threshold value normal for a communications network, operating at acceptable error rate. The results of the comparison set error flags if the limits are exceeded indicating possible future station failures.
