Cisco ONS 15454 SDH Procedure Guide, R7.0
13-2
This procedure upgrades a point-to-point configuration (two nodes) to a
linear add/drop multiplexer (ADM) configuration (three or more nodes)
by adding a node to a 1+1 protection group without losing traffic.
Compatible hardware
Attenuators might be needed for some applications.
The in-service topology upgrade procedure requires that the node to be
added is reachable (has IP connectivity with Cisco Transport Controller
[CTC]). Two technicians who can communicate with each other during
the upgrade might be needed if the PC running CTC and the
ONS 15454 SDH nodes are not at the same location.
As needed

The terminal network has no critical or major alarms.
The node that you will add has no critical or major alarms.
The node has compatible software version with that of the terminal nodes.
The node has four unused optical ports matching the speed of the 1+1 protection and no DCC has
been provisioned on these four ports.
Fiber is available to connect the added node to the terminal nodes.
