ABSTRACT:
A repeater-installed fault location mechanism conducts parametric measurements on a segment of wireline to which the repeater is connected, and adjusts taps of an echo cancellation operator in the repeater transceiver equipment, in accordance with the response of the wireline to an electrical stimulus imparted to the wireline segment. Information representative of the echo canceler tap coefficients is then transmitted over an overhead to a processor, to determine fault the location of a fault.
