4.8 Virtual Cable Test
The virtual cable test feature uses Time Domain Reflectometry (TDR) to test
the quality of the cables connected to the port. Some of the possible problems
than can be diagnosed include opens, shorts, cable impedance mismatch,
bad connectors, termination mismatch, and bad magnetics. It can also test the
distance to the problem location, with the precision of ±1 meter.
