Abstract
Proposed is an improved method of determining the location of a common fault on a line in a telecommunications network. An overall performance measure is generated for each of the lines in the network based on various electrical measurements, highlighting potentially faulty lines. Nodes within the network also have a performance measure calculated based on the performance measures of the lines passing through the node. Examples of nodes include cross connection points, junction boxes, cabinets, and sections of cabling. A common faulty node is identified from all nodes along a line, based on the overall performance measures associated with those nodes. Then, all other faulty lines running through that node are identified. A distance to fault measurement is estimated for each of the identified faulty lines, using capacitance measurements for each line. A common fault location is determined based on aggregating the estimated distances to fault calculated for each of the identified faulty lines.
