The ONS 15454 offers network management flexibility. You can choose to see the

DCC-connected to the node.

DCC Connectivity

The ONS 15454 uses SONET data communication channels (SDCCs) for CTC

connectivity, automated circuit provisioning, and alarm reporting from remote

nodes. Using a node’s SDCC, CTC automatically finds and recognizes other ONS

15454s. However, during login you can choose to exclude DCC-connected nodes

from auto-discovery, which speeds up login time and reduces clutter on the

network map.

When you log into an ONS 15454 node, only ONS 15454s with DCC connectivity to

the node are autodiscovered and displayed in network view. However, you can create

a login node group to view and manage ONS 15454s that have an IP connection but

no DCC-connectivity to the login node.

For example, in Figure 16, if you logged into Node 1 you would see Node 2 and Node

3 because they have DCC connectivity to Node 1. You would not see Nodes 4, 5, and

6 because DCC connections do not exist. To view all six nodes at once, create a login

node group with the IP addresses of Nodes 1, 4, and 5. Those nodes, and all nodes

optically connected to them, will display when you log into any node in the group.
