3.5.7 Deleting NEs
Step 3 Click Save.
Note If a topological link is deleted while NEs are automatically grouped in subnetworks, CTM deletes
isolated NEs, creates a new subnetwork, and moves the deleted NEs to the new subnetwork.
If a topological link is discovered or added manually, it will result in a network that contains disjointed
subnetworks. CTM deletes the NEs from the disjointed subnetwork that contains fewer NEs, deletes the
disjointed subnetwork, and adds the deleted NEs to the subnetwork where the topological link was added
manually.
3.5.7 Deleting NEs
From the Domain Explorer tree, you can delete a single NE, multiple NEs, or out-of-service NEs.
Note Before deleting an NE, make sure to delete all links from the NE. See 3.6.8 Deleting Links, page 3-44.
3.5.7.1 Deleting a Single NE
Step 1 In the Domain Explorer tree, select the NE that will be deleted.
Step 2 In the Status tab of the Network Element Properties pane, set the Operational State field to
Out of Service; then, click Save. Click Yes in the confirmation dialog box.
Step 3 You can delete either a selected instance of the NE or all instances of the NE:
• Deleting the selected instance of the NE—Only the specific NE that you selected in the Domain
Explorer tree is deleted. To delete the selected instance of the NE, choose Edit > Delete; then, click
Yes. If this is the last instance of the NE, the NE is placed in the Deleted Network Elements group.
Note A GNE that has associated subtending NEs cannot be deleted. A subtending NE can be
disassociated from the GNE by removing the NE from the CTM domain or by assigning it
to a different GNE.
• Deleting all instances of the NE—All NEs in the user domain that have the same NE ID are deleted.
To delete all instances of the selected NE, choose Edit > Delete All; then, click Yes in the
confirmation dialog box. The NE is placed in the Deleted Network Elements group.
No client views for an NE can be opened in the Deleted Network Elements group. Also, no properties
of a deleted NE can be modified. The deleted NE and its associated data are removed from all client
views except the Domain Explorer.
Note Only out-of-service or preprovisioned NEs can be placed in the Deleted Network Elements group.
