Chapter 13 Convert Network Configurations
NTP- D154 Convert a Point-to-Point to a Linear ADM Manually
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at one of the two point-to-point nodes. If
you are already logged in, continue with Step 2.
Step 2 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83.
Step 3 Log into the node that will be added to the point-to-point configuration (the new node).
Step 4 Complete the “NTP-D24 Verify Card Installation” procedure on page 4-2 to ensure that the new node
has two STM-N cards with the same rate as the point-to-point nodes.
Step 5 Complete the “NTP-D35 Verify Node Turn-Up” procedure on page 5-2 for the new node.
Step 6 Physically connect the fibers between the point-to-point node and the new node. The fiber connections
should be connected working card to working card and protect card to protect card.
Step 7 On the new node, create a 1+1 protection group for the STM-N cards that will connect to the
point-to-point node. See the “DLP-D73 Create a 1+1 Protection Group” task on page 17-64.
Step 8 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 for
the working STM-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-D364 Provision
Multiplex-Section DCC Terminations” task on page 20-71.) Make sure to set the port administrative
state in the Create RS-DCC Termination dialog box to Unlocked.
Note DCC failure alarms appear until you create DCC terminations in the point-to-point node.
Step 9 Display the point-to-point node that will connect to the new node in CTC node view.
Step 10 Complete the “NTP-D24 Verify Card Installation” procedure on page 4-2 to ensure that the
point-to-point node has STM-N cards installed that can connect to the new node.
Step 11 Create a 1+1 protection group for the STM-N cards in the point-to-point node that will connect to the
new node. See the “DLP-D73 Create a 1+1 Protection Group” task on page 17-64 for instructions.
Step 12 Create DCC terminations on the working STM-N card in the point-to-point node that will connect to the
new node. See the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68.
(Alternatively, if additional bandwidth is needed for CTC management, complete the “DLP-D364
Provision Multiplex-Section DCC Terminations” task on page 20-71.) In the Create RS-DCC
Termination dialog box, set the port administrative state to Unlocked.
Step 13 From the View menu, choose Go to Node View to display the new node in node view.
Step 14 Complete the “NTP-D28 Set Up Timing” procedure on page 4-9 for the new node. If the new node is
using line timing, set the working STM-N card as the timing source.
Step 15 From the View menu, choose Go to Network View to display the network view to 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-D227 Disable Alarm Filtering” task on
page 19-25 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 SDH Troubleshooting Guide for procedures.
Step 17 Repeat the procedure to add an additional node to the linear ADM.
Stop. You have completed this procedure.
