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 “Setting Up Basic Node
Information” section on page 3-2.
Step 2 Set up the network information for the node. For procedures, see the “Setting Up Network Information”
section on page 3-2.
Step 3 Set up 1+1 protection for the OC-N cards in the ADM. In Figure 5-33, Slots 6 and 12 are the working
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 “Creating Protection Groups” section on page 3-9.
Step 4 For OC-N ports connecting ONS 15454s, set the SONET DCC terminations:
a. Log into a linear ADM node and select the Provisioning > Sonet DCC tabs.
b. In the SDCC Terminations section, click Create.
c. On the Create SDCC Terminations dialog box, select the working port. Click OK.
Note Terminating nodes (Nodes 1 and 3 in Figure 5-33) will have one SDCC, and intermediate
nodes (Node 2 in Figure 5-33) will have two SDCCs.
Step 5 Use the “Setting Up ONS 15454 Timing” section on page 3-12 to set up the node timing. If a node is
using line timing, set the working OC-N card as the timing source.
Step 6 Place the OC-N ports in service:
a. Open an OC-N card that is connected to the linear ADM.
b. On the Provisioning > Line tabs under Status, select In Service.
c. Click Apply.
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.
Step 2 Click the Maintenance > Protection tabs (Figure 5-34).
