Abstract
A physical layer device according to some implementations includes a cable tester that generates a test pulse on a cable and that determines a cable status including an open status, a short status, and a normal status. A cable impedance estimator communicates with the cable tester and estimates an impedance of the cable based on a reflection amplitude of the test pulse.
