23. NOTE:
The DS3 test set is used at the end equipped with DS3 circuit packs and
the M13 test set is used at end equipped with TMUX circuit packs.
At the cross-connection associated with the near-end DDM-2000, connect the
DS3 or M13 test set to the IN and OUT jacks associated with the circuit under
test.
24. Use the DS3 or M13 test set to test for error-free transmission.
25. Was the test successful (error free)?
If YES, then continue with Step 26.
If NO, then proceed to Step 35.
26. Is this the first service being placed on the group and is protection circuit pack
installed?
If YES, then continue with Step 27.
If NO, then proceed to Step 30.

test.
28. Repeat the DS3 transmission test with the DS3 or M13 test set.
29. Was the test successful (error free)?
If YES, then continue with Step 30.
If NO, then proceed to Step 35.
30. Reseat the DS3 or TMUX circuit pack associated with the circuit under test.
31. The DS3 circuit under test has passed the DS3 transmission test. Remove the
looping patch cords from the cross-connections.
32. At the near-end (and the far-end) DDM-2000, momentarily depress the
UPD/INIT button on the SYSCTL to update the SYSCTL.
