b.
In node view, double-click the controller card (15310-CL-CTX or CTX2500) with the OC-N port
that requires the loopback, such as the 15310-CL-CTX in the destination-node ONS 15310-CL.
c. Click the Maintenance > Optical > Loopback > Port tabs.
d.
Select OOS,MT from the Admin State column.
e.
Select Terminal from the Loopback Type column.
f.
Click Apply .
g. Click Yes in the confirmation dialog box.
Step 5
Continue with the “Test the Terminal Loopback Circuit” procedure on page 1-24 .
Test the Terminal Loopback Circuit
Step 1
If the test set is not already sending traffic, send test traffic on the loopback circuit.
Step 2 Examine the test traffic being received by the test set. Look for errors or any other signal information
that the test set is capable of indicating.
Step 3
If the test set indicates a good circuit, no further testing is necessary on the loopback circuit:
a. Clear the terminal loopback:
•
Double-click the card terminal node with the terminal loopback.
•
Click the Maintenance > Optical > Loopback > Port tabs.
•
Select None from the Loopback Type column for the port being tested.
• Select the appropriate state ( IS,AINS ; OOS,DSBLD ; or OOS,MT ) in the Admin State column
for the port being tested.
•
Click Apply .
• Click Yes in the confirmation dialog box.
b.
Clear the terminal loopback circuit:
•
Click the Circuits tab.
•
Choose the loopback circuit being tested.
• Click Delete .
•
Click Yes in the Delete Circuits dialog box.
If no fault is found, the entire OC-N circuit path has now passed its comprehensive series of loopback
tests. This circuit qualifies to carry live traffic.
