Chapter 3 Building the Network
3.5.8 Restoring a Deleted NE
Note • Wait until all records associated with the NE are deleted from the database before adding the NE
back again.
• The amount of time it takes to prune NEs depends on the amount of data that needs to be removed,
the amount of data in the database, the system performance, and so on. The Deleted Network
Elements group is seen by users who have add_delete_NE_group operation permission. You can
purge or undelete an NE that is in the Deleted Network Elements group only if that NE was assigned
to you.
3.5.8 Restoring a Deleted NE
Step 1 In the Domain Explorer tree, click the Deleted Network Elements group.
Step 2 Click the NE that will be restored.
Step 3 Choose Edit > Undelete.
All instances of the NE are restored to their previous locations in the Domain Explorer tree.
Note If the original parent group no longer exists, CTM does not recreate the group. Instead, CTM restores
the NE under the management domain node.
3.5.9 Searching for an NE
CTM allows you to search for a specific NE in the network. See 1.6.5.1 Finding Data in the Domain
Explorer, page 1-38.
3.6 How Do I Build Links?
A link is a connection between two termination points (TPs). CTM represents the physical connectivity
between NEs in the domain by defining the physical links between NEs. It is through these links that
circuits (if supported on the NE) are provisioned. Links can be viewed, modified, created, and deleted.
CTM automatically discovers links between CTC-based and ONS 155xx NEs. For CTC-based NEs,
links are autodiscovered only when the DCCs are created on both ends of the link. Autodiscovery
requires configuration on ONS 15501, ONS 15530, and ONS 15540 NEs. For the ONS 15216,
ONS 15302, ONS 15305, ONS 15800, ONS 15801, ONS 15808, and MDS 9000 NEs, links are
manually added.
For the CRS-1 and XR 12000, links are physical connections between CRS-1s and XR 12000s. For
autodiscovery of links and devices, CDP must be enabled. CTM queries the CRS-1 or XR 12000 for
cdp neighbors and builds the topology if the neighboring NEs have the minimum configuration required
for EMS support.
