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.
