Chapter 14 Add and Remove Nodes
NTP- D337 Add a Node to a Linear ADM Using the Wizard
Step 3 Complete “DLP-D73 Create a 1+1 Protection Group” task on page 17-64 for the two STM-N cards that
will connect to the linear ADM node.
Step 4 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 for
the working STM-N card at the new node. Make sure to set the port state in the Create RS-DCC
Termination dialog box to Unlocked. (Do not create a DCC termination on the protect card.)
Note DCC failure alarms appear until you create DCC terminations in the linear ADM node and
connect the fiber during Step 11.
Step 5 Complete the “DLP-D60 Log into CTC” task on page 17-49 at the linear ADM node that will connect
to the new node. If you are already logged in, continue with Step 6.
Step 6 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83.
Step 7 Install the STM-N cards that will connect to the new node. See “NTP-D16 Install STM-N Cards and
Connectors” procedure on page 2-7. If the cards are already installed, continue with Step 8.
Step 8 Connect the working card at the existing linear ADM node to the working card at the new node. See
“DLP-D22 Install Fiber-Optic Cables in a 1+1 Configuration” procedure on page 17-17.
Step 9 Connect the protect card at the existing linear ADM node to the protect card at the new node.
Step 10 Complete “DLP-D73 Create a 1+1 Protection Group” task on page 17-64 for the two STM-N cards that
connect to the new node.
Step 11 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 for
the working STM-N card that connects to the working card on the new node. Make sure to set the port
state in the Create RS-DCC Termination dialog box to Unlocked. (Do not create a DCC termination for
the protect card.)
Step 12 From the View menu, choose Go to Network View. Verify that the newly created linear ADM
configuration is correct. Two green span lines should appear between each linear node.
Step 13 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83 to verify
that no unexpected alarms or conditions are present.
Stop. You have completed this procedure.
NTP-D337 Add a Node to a Linear ADM Using the Wizard
Purpose This procedure adds a node between two nodes in a 1+1 protection group
without losing traffic.
Tools/Equipment
• Compatible hardware necessary for the upgrade.
• Attenuators might be needed for some applications.
Prerequisite Procedures The in-service topology upgrade procedure requires that the node to be
added is reachable (has IP connectivity with CTC). Two technicians who
can communicate with each other during the upgrade might be needed if
the PC running CTC and the ONS 15454 SDH nodes are not at the same
location.
Required/As Needed As needed
