ABSTRACT:
A fault management system is directed to the access network part of a communications network where terminating lines in the form of pairs of copper wires extend from a local switch through a series of nodes to terminal equipment provided for user of the network. Each night, a test head performs a series of tests on each of the terminating lines. The results of the tests are transmitted to an access network management system where they are analyzed with respect to a set of parameters to identify characteristics that would indicate that a fault is likely to occur on the associated circuit within a predetermined period e.g. 1 year. Further analysis can then be carried out to establish the probability of the fault actually occurring and/or whether the potential fault analyzed is going to occur in either the underground or the over-ground part of the network. Further analysis determines relative costs of repair for circuits or network elements in which faults or potential faults have been identified.
