Abstract

A fault location system for a telecommuni-cations network including a local exchange or switch, a node such as a primary connection point and a plurality of line terminations that the customer includes probability calcula-tion to establish the location of a fault; measuring from the exchange. Historical non-faulty reference values of capac-itance are compiled for each line passing through the node providing a measure of the distance of each line. A
low-est valid capacitance value provides an estimate of the ref-erence capacitance between the exchange and the node. A
histogram is compiled of historic fault values and a new fault is compared against the histogram to establish the probabil-ity of it being a fault at the node or elsewhere. As a result the reference capacitance can be obtained without the need for an engineer at the node, and the likely location of a fault can be pinpointed with greater accuracy.
