DLP- D88 Optical 1+1 Protection Test
Step 6 On the SOCKS Proxy Server Settings page, choose one of the following:
• External Network Element (ENE)—If selected, the CTC computer is only visible to the
ONS 15454 SDH to which the CTC computer is connected. The computer is not visible to the
DCC-connected nodes. In addition, firewall is enabled, which means that the node prevents IP traffic
from being routed between the DCC and the LAN port.
• Gateway Network Element (GNE)—If selected, the CTC computer is visible to other
DCC-connected nodes. The node prevents IP traffic from being routed between the DCC and the
LAN port.
• Proxy-only—If selected, the ONS 15454 SDH responds to CTC requests with a list of
DCC-connected nodes for which the node serves as a proxy. The CTC computer is visible to other
DCC-connected nodes. The node does not prevent traffic from being routed between the DCC and
LAN port.
Step 7 Click Finish.
Within the next 30 to 40 seconds, the TCC2P cards reboot. CTC switches to network view, and the CTC
Alerts dialog box appears. In network view, the node changes to grey and a DISCONNECTED condition
appears.
Step 8 In the CTC Alerts dialog box, click Close. Wait for the reboot to finish. (This might take several
minutes.)
Step 9 Return to your originating procedure (NTP).

Step 1 From the View menu, choose Go to Network View.
Step 2 Click the Alarms tab.
a. Verify that the alarm filter is not on. See the “DLP-D227 Disable Alarm Filtering” task on
page 19-25 as necessary.
b. Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve
them before continuing. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide if necessary.
Step 3 Click the Conditions tab. Verify that no unexplained conditions appear on the network. If unexplained
conditions appear, resolve them before continuing. Refer to the Cisco ONS 15454 SDH Troubleshooting
Guide if necessary.
Step 4 On the network map, double-click the node containing the 1+1 protection group you are testing to open
it in node view.
Purpose This task verifies that a 1+1 protection group will switch traffic properly.
Tools/Equipment The test set specified by the acceptance test procedure.
