Zusammenfassung:	An apparatus for detecting and locating a fault in a wired communication network, the apparatus comprises a channel estimator (408) for performing channel estimation to obtain a time domain channel response on an echo channel; and a processor (406) to identify a reference latency for the apparatus; analyze the time domain channel response to determine whether there is any change from a previously obtained time domain channel response on the echo channel, and estimate a location of a fault in the wired communication network using the reference latency and based on the time domain channel response if there is a change from the previously obtained time domain channel response.
