“Bad Patch Cord” Message

Figure 29. Channel Connections
“Bad Patch Cord” Message
To comply with standards for tests on channels, the tester
removes the effects of the channel adapters and their
connections from the test results. Before it removes these effects,
the tester makes sure that the plugs on the patch cord do not
have too much near-end crosstalk (NEXT). Too much NEXT is
frequently caused by too much untwisted wire in the plug. If a
plug is bad, the tester shows the message Bad patch cord at main
or Bad patch cord at remote, and does not remove the effects of
the channel adapters and their connections. The tester saves the
message with the results.
If you see one of these messages, replace the patch cord or install
a new plug at the bad end.
