the ring network, 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.
39. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
