Send and Monitor 511
The Send and Monitor 511 test causes the local and remote units to send a 511
test pattern to each other. The front panel Test LEDs of both units are on during
the test. The duration and results of the test are displayed on the Network Test
screen of the initiating unit. The card will send ones in the G.703 timeslots that are
mapped to the DSL port in test.
NOTE:
The Send and Monitor 511 test is not a loopback test. Each unit independently
sends and monitors a 511 pattern.
Procedure

1. Position the cursor at the Start command next to Send and Monitor 511 on the
Network & DSX-1 Tests screen or the Network & G.703 Tests screen.
2. Press Enter.
The Start command is changed to Stop.
3. To manually stop the test, verify that the cursor is positioned at the Stop

to the test duration, and the R
