Chapter 1 General Troubleshooting

Identify Points of Failure on an OC-N Circuit Path

e. In the Circuit Source dialog box, fill in the source Node, Slot, Port, and Type where the test set is

connected and click Next.

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

port in the destination 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. Go to the node view of the destination node:

• From the View menu, choose Go To Other Node.

• Choose the node from the drop-down list in the Select Node dialog box and click OK.

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 Termin al 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 1-27.

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.
