System and method for detecting anomalies along telecommunication lines

摘要

An anomaly detection system comprises an echo canceler and anomaly detection logic. The echo canceler has a plurality of taps respectively associated with a plurality of tap coefficients. The anomaly detection logic is configured to determine a difference between a new tap coefficient associated with one of the taps and a previous tap coefficient associated with the one tap. The anomaly detection logic is configured to perform a comparison between the difference and a threshold and to detect an anomaly along a telecommunication line based on the comparison.

1. An anomaly detection system, comprising:
a telecommunication line having a plurality of wires including at least a first wire joined to a second wire, the telecommunication line having a time varying anomaly at a junction of the first wire and the second wire, the time varying anomaly causing a transmission characteristic of the telecommunication line to fluctuate at the junction; a transmitter coupled to the telecommunication line; and anomaly detection logic configured to detect the anomaly based on signals communicated across the telecommunication line, the anomaly detection logic further configured to indicate a location of the detected anomaly along the telecommunication line.
