Chapter 1 General Troubleshooting

Identify Points of Failure on an OC-N Circuit Path

c. Adjust the test set accordingly.

Step 2 Use CTC to set up the facility loopback circuit on the port being tested:

a. Click the Circuits tab and click Create.

b. Give the circuit an easily identifiable name, such as OCN1toOCN5.

c. Set circuit Type and Size to the normal preferences, such as STS and STS1.

d. Leave the Bidirectional check box checked and click Next.

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 2.7.162 LPBKFACILITY (OCN) condition to appear during a loopback setup.

The condition clears when you remove the loopback.

Step 4 Create the facility 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 15310-CL-CTX or CTX2500 card with the OC-N port that requires

the loopback.

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.

Note It is normal for a 2.7.162 LPBKFACILITY (OCN) condition to appear during loopback

setup. The condition clears when you remove the loopback.

Step 5 Continue with the “Test the Facility Loopback Circuit” procedure on page 1-25.

Test the Facility Loopback Circuit

Step 1 If the test set is not already sending traffic, send test traffic on the loopback circuit.

Step 2 Examine the traffic 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 with the facility loopback:

1 2 ... 56 57 58 59 60 61 62 63 64 65 66 ... 379 380
