1.4 Troubleshooting Wideband Electrical Card(W BE-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 ONS15310-CL.
c. Click the Maintenance > Optical > Loopback > Port tabs.
d. Select OOS,MT from the Admin State column.
e. Select Term in al from the Loopback Type column.
f. Click Apply.
g. Click Yes in the confirmation dialog box.
Step5 Continue with the “Test the Terminal Loopback Circuit” procedure on page1-25.
Test the Terminal Loopback Circuit
Step1 If the test set is not already sending traffic, send test traffic on the loopback circuit.
Step2 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.
Step3 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.
1.4 Troubleshooting Wideband Electrical Card(WBE-28 and WBE-84 Cards) FEAC on DS3 Ports
WBE-28/WBE-84 cards support far-end alarm and control(FEAC) functions on DS3 ports. Click the
WBE-28/WBE-84 Maintenance > DS3 tabs at the card view to reveal the two additional function
