Abstract
A digital subscriber loop line card-installed mechanism conducts parametric measurements on the wireline to which the line card is connected, and adjusts taps of an echo cancellation operator in accordance with the response of the wireline to an electrical stimulus imparted to the wireline. The echo canceler tap coefficients are then processed to determine the location of a fault, such as a short circuit, open-circuit and the like, on the wireline. Fault information measurement data is then reported to a supervisory control location, which dispatches the appropriate technician to resolve the cause of the problem.
