DDM-2000 OC-3 MULTIPLEXER
13. Use the following command to switch from service to protection circuit pack:
switch-ls:address:pri=manual;.
Response: The green ACTIVE LED lights on the protection circuit
pack.
14. Repeat the transmission test in the mux (or demux) direction using the
following command:
test-trmsn-t1:address:dirn=mux (or demux):dur=( );.
15. Was the test successful (error free)?
If YES, then continue with Step 16.
If NO, then proceed to Step 37.
16. Use the following command to clear active switch requests on the protection
circuit pack:
switch-ls:address:pri=reset;.
17. The DS1 circuit path under test has passed the DS1 transmission test. Have
all required paths been tested?
If NO, then continue with Step 18.
If YES, then proceed to Step 19.
18. Repeat this procedure from Step 4 for the next path to be tested.
19. Remove the looping patch cords from the cross-connect point. Use the
rls-lpbk-t1: command to release loopback(s) at the far end, if required.
20. At the near-end (and the far-end) DDM-2000, momentarily depress the
UPD/INIT button (or use the upd command) on the SYSCTL to update the
SYSCTL.
21. Repeat this procedure from Step 2 for any additional DS1 circuits to be tested.
22. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
23. At the cross-connection associated with the near-end DDM-2000, connect the
DS1 test set to the IN and OUT jacks associated with the circuit under test.
24. Use the DS1 test set to test for error-free transmission.
