Test Commands
The test commands enable you to run loopbacks and test patterns on the CSU,
and to test the front panel LEDs. These tests can help you isolate areas of trouble
if you are having problems with your CSU.
To access all Test commands from the Test branch, press F2 to select Test from
the top-level menu screen.
Remote Loopback Tests

following to a far-end device:

You cannot perform remote loopbacks if any of the local loopbacks are active. If
you attempt to do so, the error message
