ABSTRACT:
Methods and apparatus to perform and/or analyze communication channels are described. In one embodiment, a test signal may be generated and transferred using a first signal route to a line-under-test in response to line qualification mode. The first signal route may include a compensation device to modify the test signal. In some embodiments, a reflected signal from the line-under-test may be received in response to the test signal. A second signal route may be utilized to route the reflected signal in response to line qualification mode.
