31. The DS3 circuit path under test has passed the DS3 transmission test. Have
all required paths been tested?
If NO, then continue with Step 32.
If YES, then proceed to Step 33.
32. Repeat this procedure from Step 4 for the next path to be tested.
33. Remove the looping patch cords from the cross-connections.
34. At the near-end (and the far-end) DDM-2000, momentarily depress the
UPD/INIT button on the SYSCTL to update the SYSCTL.
35. Repeat this procedure from Step 2 for any additional DS3 circuits to be tested.
36. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
37. Has the DS3 circuit pack that failed been replaced?
If YES, then proceed to Step 40.
If NO, then continue with Step 38.

Reference: DLP-523
39. Repeat this procedure for the DS3 circuit pack that failed.
40. Trouble may be in the DSX cross-connect wiring, STS1 cross-connections in
the network (if ring configuration), or the shelf backplane. Use the
rtrv-crs-sts1: command to ensure proper STS1 cross-connections have
been made at each shelf in the ring for the DS3 being tested. If no trouble
found, check DSX cross-connect wiring and backplane connections. If other
alarms or trouble indications are present, refer to Trouble Clearing: IXL-001
to isolate the trouble. If no alarms or indications are present and a CIT is
available, use the RETRIEVE commands (for example, rtrv-alm,
rtrv-hsty, etc.) to check for other trouble indications.
41. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
