1. A method comprising:
determining, by a receiver, a forward time value comprising a time a forward signal takes to travel from a transmitter over a channel to the receiver;
determining, by the receiver, a reflected time value comprising a time a reflected signal takes to travel to the receiver, wherein the reflected signal is associated with the forward signal; and
determining that a discontinuity exists on the channel based on the forward time value and the reflected time value, wherein the reflected signal is caused by the discontinuity and a high impedance or low impedance at the transmitter present after the forward signal is sent wherein the high impedance is higher than a nominal impedance of the transmitter and the low impedance is lower than the nominal impedance of the transmitter.
