NTP-G130 Remove a DWDM Node
Step 5 If OCHNC circuits pass through the node to be removed on the active path and are protected by a splitter
or Y-cable protection group, navigate to a node connected to the node that will be removed and complete
the “DLP-G179 Apply a Force Y-Cable or Splitter Protection Switch” task on page 10-35. Otherwise,
continue with Step 6.
Step 6 Complete the following steps for each circuit identified in Step 4 that was not switched in Step 5:
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 OOS,DSBLD (ANSI) or Locked,disabled (ETSI).
Step 7 Delete the cross-connects on the node that will be removed for each circuit placed in the OOS-DSLBD
or Locked,disabled state in Step 6:
a. From the Tools menu, choose Open TL1 Session.
b. In the Select Node dialog box, select the new node and click OK.
c. In the TL1 dialog box, use the DLT-WLEN command to delete the OCHNC cross-connects for each
unprotected pass-through circuit as follows:
DLT-WLEN:[<TID>]:<AID>:<CTAG>:::[SIZE=<SIZE>]:[<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
Reference Guide or the Cisco ONS 15454 SDH TL1 Reference Guide.
d. Close the TL1 dialog box.
e. Repeat Step 6 to change the circuits placed in OOS-DSLBD back in service by changing the Target
circuit Admin State field to IS,AINS (ANSI) or Unlocked,automaticInService (ETSI).
Step 8 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 5.
Step 9 Complete the “DLP-G106 Delete Optical Channel Network Connections” task on page 7-12 to delete
circuits identified in Step 4 that will terminate (add/drop) on the new DWDM node.
Step 10 Complete the “DLP-G105 Provision DWDM Optical Channel Network Connections” task on page 7-10
to recreate circuits identified in Step 4 that will terminate on the new DWDM node. Choose the new
DWDM node as the start/end (add/drop, respectively) for each circuit.
Step 11 Complete the “DLP-G105 Provision DWDM Optical Channel Network Connections” task on page 7-10
to create new circuits that originate or terminate in the new DWDM node.
Stop. You have completed this procedure.
