Chapter 14 Add and Remove Nodes
NTP- D353 Add an MS-SPRing Node
See the “DLP-D65 Create a Static Route” task on page 17-56. To view gateway settings, see the
“DLP-D249 Provision IP Settings” task on page 19-52.
Step 8 Complete the “DLP-D60 Log into CTC” task on page 17-49 at a node that is in the MS-SPRing.
Step 9 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83 to verify
that the MS-SPRing is free of major alarms or problems. If trouble is indicated (for example, a major
alarm exists), resolve the problem before proceeding. See Chapter 9, “Manage Alarms” or, if necessary,
refer to the Cisco ONS 15454 SDH Troubleshooting Guide.
Step 10 Click the Provisioning > MS-SPRing tabs.
Step 11 On paper, record the Ring ID, Ring Type, Line Rate, Ring Reversion, and Span Reversion (4 Fiber).
Step 12 From the Node column, record the Node IDs in the MS-SPRing. The Node IDs are the numbers in
parentheses next to the node name.
Step 13 Log into the new node:
• If the node has a LAN connection and it appears on the network map, from the View menu, choose
Go to Other Node, then enter the new node.
• If the new node is not connected to the network, complete the “DLP-D60 Log into CTC” task on
page 17-49.
Step 14 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 15 Using the information recorded in Steps 11 and 12 and the diagram created in Step 2, create an
MS-SPRing on the new node. See the “DLP-D242 Create an MS-SPRing on a Single Node” task on
page 19-45.
Step 16 (Optional) Create test circuits, making sure they pass through the MS-SPRing trunk cards and run test
traffic through the node to ensure the cards are functioning properly. See the “NTP-D324 Create a
Manually Routed High-Order Circuit” procedure on page 6-60 and the “NTP-D62 Test High-Order
Circuits” procedure on page 6-66 for information.
Step 17 Create the data communications channel (DCC) terminations on the new node. See the “DLP-D363
Provision Regenerator-Section DCC Terminations” task on page 20-68.
Note Creating the DCC terminations causes the Regenerator Section DCC (RS-DCC) Termination
Failure (EOC) and Loss of Signal (LOS) alarms to appear. These alarms remain active until you
connect the node to the MS-SPRing.
Note If you map the K3 byte to another byte (such as E2), you must remap the trunk cards on either
side of the new node to the same byte. See the “DLP-D89 Remap the K3 Byte” task on
page 17-83.
Step 18 Complete the “DLP-D60 Log into CTC” task on page 17-49 at an MS-SPRing node that will connect to
the new node.
Step 19 Referring to the diagram created in Step 2, complete the “DLP-D303 Initiate an MS-SPRing Force Ring
Switch” task on page 20-3 on the node that will connect to the new node on its west line (port). In the
Figure 14-2 example, the MS-SPRing force ring would occur at Node 1, West line (Slot 5 and 6).
