Chapter 12 Add and Remove Cards and Nodes
NTP-G129 Add a DWDM Node
Step 4 In network view, click the Circuits tab.
Step 5 Identify the OCHNCs that are carried on the fiber span that you identified in Step 2 in both the
east-to-west and west-to-east directions.
Step 6 If the OCHNC circuit is on the active path and is protected by a splitter or Y-cable protection group,
complete the “DLP-G179 Apply a Force Y-Cable or Splitter Protection Switch” task on page 10-35 to
force traffic away from the span where the node will be added. If not, continue with Step 7.
Step 7 For each circuit identified in Step 5 that was not switched in Step 6 (unprotected circuits), complete the
following steps:
a. Select the circuit and click Edit.
b. In the Edit Circuit dialog box, click the State tab.
c. In the Target Circuit Admin State field, choose choose OOS,DSBLD (ANSI) or Locked,disabled
(ETSI).
Step 8 Remove the fibers from the cards at the adjacent nodes that will connect to the new node.
Step 9 At the node that will be added, complete the following procedures and tasks:
• NTP-G22 Verify Common Card Installation, page 3-4
• NTP-G26 Set Up CTC Network Access, page 3-11
• NTP-G30 Install the DWDM Cards, page 3-39
• NTP-G36 Calculate Cable Connections, page 3-80
• NTP-G138 Import a Cisco MetroPlanner Configuration File, page 3-82
• NTP-G37 Run Automatic Node Setup, page 3-83
• Node acceptance tests in Chapter 4, “Perform Node Acceptance Tests”
Step 10 Create cross-connects on the new node for all circuits identified in Step 5:
a. From the Tools menu, choose Open TL1 Session.
b. In the Select Node dialog box, choose the new node and click OK.
c. In the TL1 dialog box, use the ENT-WLEN command to create the OCHNC cross-connects for each
unprotected pass-through circuit as follows:
ENT
-WLEN:
[<TID>]
:<AID>:<CT
A
G>:::[SI
ZE=<SIZ
E>]:[<PST
>],[<SST>];
where:
–
<AID> is the wavelength AID.
–
<SIZE> is the circuit size allocated on this wavelength.
–
<PST> is the primary state.
–
<SST> is the secondary state.
For additional information and a list of valid command values, see the Cisco ONS SONET TL1
Command Guide or the Cisco ONS 15454 SDH TL1 Command Guide.
d. Close the TL1 dialog box.
e. Repeat Step 7 to change the circuits placed in OOS-DSLBD or Locked,disabled back in service by
choosing IS,AINS (ANSI) or Unlocked,automaticInService (ETSI).in the Target Circuit Admin
State field.
Step 11 Complete the “DLP-G180 Clear a Manual or Force Y-Cable or Splitter Protection Switch” task on
page 10-36 for the circuits that were switched in Step 7.
