Note In a linear ADM configuration, two OC-N cards in 1+1 protection are connected to two OC-N cards in
1+1 protection on a second node. On the second node, two more OC-N cards are connected to a third
node. The third node can be connected to a fourth node, and so on, depending on the number of nodes
in the linear ADM. Slots 1 to 4 and 14 to 17 or Slots 5 to 6 and 12 to 13 can be used if connections
between nodes are consistent. For example, Slot 5 on the first linear ADM node connects to Slot 5 on
the second linear ADM node for the working path, and Slot 6 connects to Slot 6 for the protect path. The
working OC-N ports have DCC terminations, and the OC-N cards are in a 1+1 protection group.

This procedure adds a single ONS 15454 node to the end of an
ONS 15454 linear add-drop multiplexer (ADM) network. If the linear
ADM carries traffic, you cannot add a node between two linear ADM
nodes using this procedure unless you delete and recreate the circuits.
To avoid deleting and recreating the circuits, use the
