Abstract:
1. An apparatus comprising: a test signal generator to provide a test signal and selectively transfer the test signal using a first signal route to a line-under-test in response to line qualification mode, wherein the first signal route includes a compensation device to modify the test signal; a receiver to receive a reflected signal from the line-under-test, wherein the reflected signal comprises a signal reflected by the line-under-test in response to the test signal, wherein the receiver selectively uses a second signal route to route the reflected signal in response to line qualification mode; and a signal processor to modify one of a duration and amplitude of the test signal based on the reflected signal, wherein the first signal route comprises a route to bypass a hybrid line interface element and the second signal route comprises a route to bypass the hybrid line interface element, wherein the first signal route and second signal route are to bypass the hybrid line interface to reduce introduction of board echo attributable to the hybrid line interface.
