Abstract

A line test system for diagnosing and segmenting faults in a switched telephone network. The system includes a remote measurement unit 120) installed at a switch (106) and a test system controller (132). The test system controller (132) stores data about operating parameters of each of the subscriber lines (108) when they are believed to be free of faults. When a fault is reported, the parameters are measured again. By comparison of the measured parameters with the stored parameters, the fault can be segmented between the premise and the network. Segmentation is performed using knowledge based analysis techniques. The actual source of the fault once it is repaired is also stored by the test system controller (132). This historical information is used to improve the accuracy of the knowledge based analysis techniques used for segmentation.
