Chapter 2 Alarm Troubleshooting

2.10.4 Generic Signal and Circuit Procedures

d.Verify that the Disable OSPF on Link check box is unchecked.

e.Click OK.

Clear an OC-N Port Facility or Terminal Loopback Circuit

Step 1 Log into a node on the network. If you are already logged in, continue with Step 2.

Step 2 Double-click the 15310-CL-CTX or CTX2500 card in CTC to display the card view.

Step 3 Click the Maintenance > Optical > Loopback > Port tabs.

Step 4 In the Loopback Type column, determine whether any port row shows a state other than None.

Step 5 If a row contains another state besides None, click in the column cell to display the drop-down list and select None.

Step 6 In the Admin State column, determine whether any port row shows a state other than IS.

Step 7 If a row shows a state other than IS, click in the column cell to display the drop-down list and select IS. Step 8 Click Apply.

Note If ports managed into IS administrative state are not receiving signals, the LOS alarm is either raised or remains, and the port service state transitions to OOS-AU,FLT.

Clear an OC-N Port XC Loopback Circuit

Step 1 Log into a node on the network. If you are already logged in, continue with Step 2.

Step 2 Double-click the reporting card in CTC to display the card view.

Step 3 Click the Maintenance > Optical > Loopback > SONET STS tabs.

Step 4 Uncheck the XC loopback check box.

Step 5 Click Apply.

Clear a DS-3 or DS-1 Port Loopback Circuit

Step 1 Log into a node on the network. If you are already logged in, continue with Step 2.

Step 2 Double-click the 15310-CL-CTX or CTX2500 card in CTC to display the card view.

Step 3 Click the Provisioning > DS3 or the Maintenance > DS1 tabs.

Step 4 In the Loopback Type column, determine whether any port row shows a state other than None.

Step 5 If a row contains another state besides None, click in the column cell to display the drop-down list and select None.

Step 6 In the Admin State column, determine whether any port row shows a state other than IS.
