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
Step 2
Set up the network information for the node. For procedures, see the
.
Step 3
, 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
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:
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
) will have one SDCC, and intermediate
nodes (Node 2 in
) will have two SDCCs.
Step 5
Use the
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.
