Linear ADM Configurations
Procedure: Create a Linear ADM
Complete the following steps for each node that will be included in the linear ADM.
Step 1
Complete the general setup information for the node. For procedures, see the
Information" section on page
Set up the network information for the node. For procedures, see the
Step 2
section on page
Set up 1+1 protection for the OC-N cards in the ADM. In
Step 3
ports and Slots 5 and 13 are the protect ports. In this example, you would set up one protection group
for Node 1 (Slots 5 and 6), two for Node 2 (Slots 5 and 6, and 12 and 13) and one for Node 3 (Slots 12
and 13). To create protection groups, see the
Step 4
For OC-N ports connecting ONS 15454s, set the SONET DCC terminations:

using line timing, set the working OC-N card as the timing source.
Place the OC-N ports in service:

c.
Repeat Step 6 for each OC-N card connected to the linear ADM.
Procedure: Convert a Linear ADM to UPSR
The following procedures describe how to convert a three-node linear ADM to a UPSR. You will need
a SONET test set to monitor traffic while you perform these procedures.
Caution
This procedure is service affecting.
Caution
Always wear an authorized electrostatic discharge wrist band when removing or installing ONS
15454 cards.
Step 1
Start CTC and log into one of the nodes that you want to convert from linear to ring.
