DDM-2000 OC-3 MULTIPLEXER
22.
NOTE:
The DS1 test set is used at the end equipped with DS1/DS1PM or T1EXT
circuit packs and the M13 test set is used at the end equipped with TMUX
circuit packs.
At the near-end DDM-2000 cross-connect point or T1 interface, connect the
DS1 or M13 test set to the IN and OUT jacks associated with the circuit under
test.
23. Use the DS1 or M13 test set to test for error-free transmission.
24. Was the test successful (error free)?
If YES, then continue with Step 25.
If NO, then proceed to Step 34.
25. Is this first service being placed on the group and is protection circuit pack
installed?
If YES, then continue with Step 26.
If NO, then proceed to Step 30.
26. Unseat the service DS1/DS1PM, TMUX,orT1EXT circuit pack associated
with the circuit under test.
27. Repeat the DS1 transmission test with the DS1 or M13 test set.
28. Was the test successful (error free)?
If YES, then continue with Step 29.
If NO, then proceed to Step 34.
29. Reseat the DS1/DS1PM, TMUX,orT1EXT circuit pack associated with the
circuit under test.
30. The DS1 circuit under test has passed the DS1 transmission test. Remove the
looping patch cords from the cross-connections.
31. At the near-end (and the far-end) DDM-2000, momentarily depress the
UPD/INIT button on the SYSCTL to update the SYSCTL.
32. Repeat this procedure from Step 21 for any additional DS1 circuits to be
tested.
33. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
