Abstract
A fault detection system and a processor implemented method of detecting a wire fault in a wired network are described. The wired network services a set of customer equipment devices. In one aspect, a method comprises: obtaining, from a plurality of the customer equipment devices, pre-equalization coefficients associated with equalizers of the plurality of the customer equipment devices; determining tap energies for taps associated with the equalizers based on the pre-equalization coefficients; selecting one of the taps; for each of a plurality of the customer equipment devices, assigning the customer equipment device to one of a plurality of groups by comparing the tap energy for the selected tap for that customer equipment device to thresholds associated with the groups; and determining that a wire fault is probable when one of the groups includes at least a threshold number of customer equipment devices.
