NTP-A303 Convert an Unprotected Point-to-Point or 1+1 Linear ADM to a Two-Fiber BLSR Automatically
Step 8 Complete the “DLP-A377 Provision Section DCC Terminations” task on page 20-61 for the working
OC-N cards in the new node that will connect to the linear ADM network. Alternatively, if additional
bandwidth is needed for CTC management, complete the “DLP-A378 Provision Line DCC Terminations”
task on page 20-62.
Note DCC failure alarms appear until you create DCC terminations in the point-to-point node during
Step 9.
Step 9 In node view, display the point-to-point node that will connect to the new node.
Step 10 Complete the “NTP-A24 Verify Card Installation” procedure on page 4-2 to ensure that the
point-to-point node has OC-N cards installed that can connect to the new node.
Step 11 Create a 1+1 protection group for the OC-N cards that will connect to the new node. See the “DLP-A73
Create a 1+1 Protection Group” task on page 17-81 for instructions.
Step 12 Create DCC terminations on the working OC-N card that will connect to the new node. See the
“DLP-A377 Provision Section DCC Terminations” task on page 20-61.
Step 13 From the View menu, choose Go to Node View to open the new node in node view.
Step 14 Complete the “NTP-A28 Set Up Timing” procedure on page 4-9 for the new node. If the new node is
using line timing, make the working OC-N card the timing source.
Step 15 From the View menu, choose Go to Network View. Verify that the newly created linear ADM
configuration is correct. One green span line should appear between each linear node.
Step 16 Click the Alarms tab.
a. Verify that the alarm filter is not on. See the “DLP-A227 Disable Alarm Filtering” task on
page 19-17 as necessary.
b. Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve
them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide for procedures.
Step 17 Repeat the procedure to add an additional node to the linear ADM.
Stop. You have completed this procedure.
NTP-A303 Convert an Unprotected Point-to-Point or 1+1 Linear
ADM to a Two-Fiber BLSR Automatically
Purpose This procedure converts an unprotected point-to-point (two nodes) or
linear ADM (three or more nodes) to a two-fiber bidirectional line
switched ring (BLSR) without disrupting traffic.
