12. Is this first service being placed on the group and is a protection DS1,
DS1PM, or T1EXT circuit pack installed?
If YES, continue with Step 13.
If NO, proceed to Step 17.
13. Use the following command to switch from service to protection circuit pack:
switch-ls:
address
:pri=manual;.
14. Repeat the transmission test in the mux (or demux) direction using the
following command:
test-trmsn-t1:
address
:dirn=mux (or demux):dur=( );.
15. Was the test successful (error free)?
If YES, continue with Step 16.
If NO, proceed to Step 36.
16. Use the following command to clear active switch requests:
switch-ls:
address
:pri=reset;.
17.
NOTE:
If this is a single-ring configuration and the transmission test is being
performed in the mux direction, use the switch-path command to
switch the path to the other ring and then repeat this test before releasing
loopbacks.
The DS1 circuit under test has passed the DS1 transmission test. Remove the
looping patch cords from the cross-connect point. Use the rls-lpbk-t1
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 button on the SYSCTL (or use the upd command) to update the
SYSCTL and remove alarms after the loopbacks have been removed.
19. Repeat this procedure from Step 3 for any additional DS1 circuits to be tested.
20. Use the rtrv-sync and switch-sync:s=
mode
:pri=reset commands to
verify/switch timing mode back to
LoopTimed
.
21. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
