Abstract
Failure of a local exchange in a communications network (such as the PSTN) is detected by monitoring a combination of parameters. Each parameter in the combination is monitored for meeting predetermined criteria. In particular, a local exchange failure is recognized when the average value of the All Circuits Engaged (ACE) parameters over all traffic routes into a local exchange rises in a significant manner and the average value of the Circuits in Service (CCTS IS) parameters over all traffic routes into that exchange decreases in a significant manner.
