An expert network analyzer: fault diagnosis and prediction

We present the framework of an expert system that will be capable of diagnosing and predicting faults in a cable television plant. The structure of the diagnostic expert system under development comprises equipment specific and network specific parts. We present the integration of status monitoring data into our system and their use in determining failure points in the network. Once a failure point has been reliably determined, then the equipment part of the system is used to diagnose the failure. The cause of failure is determined at either the network level, the equipment level or both
