13. Use the following command to switch from service to protection circuit
pack:switch-fn:
address
:pri=manual;.
Response: The green ACTIVE LED lights on the protection circuit
pack.
14.
NOTE:
If this is a single-ring configuration and the transmission test is being
performed in the mux direction, the switch-path command should be
used to switch the path to the other ring and then repeat this test.
Repeat the transmission test in the mux (or demux) direction using the
following command: test-trmsn-t3:
address
:dirn=mux (or
demux):dur=( );).
15. Was the test successful (error free)?
If YES, continue with Step 16.
If NO, proceed to Step 34.
16. Use the following command to clear active switch requests:
switch-fn:
address
:pri=reset;.
17. The DS3 circuit under test has passed the DS3 transmission test. Remove the
looping patch cords from the cross-connect point. Use the rls-lpbk-t3
command to release loopback(s) at the far end; if required.
18. At the near end (and the far end) DDM-2000, momentarily depress the
UPD/INIT pushbutton (or use the upd command) on the SYSCTL to update
the SYSCTL.
19. If violation monitor removal mode was set differently than the original mode in
Step 5, reprovision the mode to the original or required setting using the
set-t3 command. Repeat this procedure from the Step 2 for any additional
DS3 circuits to be tested.
20. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
21. See Figure 1. If local tests are being performed, the fiber loopback at the
near-end OLIU must be in place. If end-to-end tests are being performed, at
DSX-3 to STSX cross-connect point associated with the DDM-2000 being
tested, connect a patch cord from the OUT jack to the IN jack for the DS3
channel to be tested.
