displays a total of the 511 errors; that is, if 511 errors are being received, the display updates accordingly.

TSU LT, and send a 511 pattern from the local TSU LT. Then, view the
CLR E

screen to determine
if the link is functioning properly by verifying that no errors are being counted.

When running a 511 pattern test, press the
E
NTER
key to insert an error into the 511 pattern.
