Send and Monitor 511
The LTU initiates the test by lighting the Test LED sending a command to the
remote unit to send a 511 test pattern. When the remote unit detects the
command, it sends a 511 pattern and lights the front panel test LED. Each unit
will send and monitor the 511 pattern. The duration and results of the test are
displayed on the Network Test screen of each unit.
NOTE:
The send and monitor test is not a loopback test. Each unit independently
sends and monitors a 511 pattern.
