1. An anomaly detection system, comprising:
- an echo canceler having a plurality of taps respectively associated with a plurality of tap coefficients; and
anomaly detection logic 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 configured to perform a comparison between the difference and a threshold and to detect an anomaly along a telecommunication line based on the comparison.

Abstract
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.
