Chapter 1 General Troubleshooting

Identify Points of Failure on an OC-N Circuit Path

g. In the Circuit Destination dialog box, fill in the destination Node, Slot, Port, and Type (the OC-N

port in the source node) and click Finish.

Step 3 Confirm that the newly created circuit appears on the Circuits tab list as a two-way circuit.

Note It is normal for a 2.7.166 LPBKTERMINAL (OCN) condition to appear during a loopback

setup. The condition clears when you remove the loopback.

Step 4 Create the terminal loopback on the destination port being tested:

a. In node view, double-click the card that requires the loopback.

b. Click the Maintenance > Optical > Loopback > Port tabs.

c. Select OOS,MT from the Admin State column.

d. Select Termin al from the Loopback Type column.

e. Click Apply.

f. Click Yes in the confirmation dialog box.

Step 5 Continue with the “Test the Terminal Loopback Circuit” procedure on page 1-20.

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.

If the test set indicates a good circuit, no further testing is necessary on the loopback circuit:

Step 3 Clear the terminal loopback:

a. Double-click the card in the source node having the terminal loopback.

b. Click the Maintenance > Optical > Loopback > Port tabs.

c. Select None from the Loopback Type column for the port being tested.

d. Select the appropriate state (IS,AINS; OOS,DSBLD; or OOS,MT) in the Admin State column for

the port being tested.

e. Click Apply.

f. Click Yes in the confirmation dialog box.

Step 4 Clear the terminal loopback circuit:

a. Click the Circuits tab.

b. Choose the loopback circuit being tested.

c. Click Delete.

d. Click Yes in the Delete Circuits dialog box.

Step 5 If the test set indicates a faulty circuit, the problem might be a faulty port. Continue with the

“1.3.4 Perform a Facility Loopback on an Intermediate-Node OC-N Port” procedure on page 1-21.
