Abstract

A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems.
