The Cable Diagnostics Summary Page contains fields for viewing tests on 
copper cables. Cable testing provides information about where errors 
occurred in the cable, the last time a cable test was performed, and the 
type of cable error which occurred. The tests use Time Domain 
Reflectometry (TDR) technology to test the quality and characteristics of a 
copper cable attached to a port.
