1.4 Troubleshooting Wideband Electrical Card(WBE-28 and WBE-84 Cards) FEAC on DS3 Ports
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 1-25.
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.
