Step 12 Remove the OC-N cards that are no longer connected to the end nodes (Slots 1 and 4, in the example).
Display one of the end nodes (Node 1 or Node 3 in the example).

Click the Provisioning > Sonet DCC tabs.
Step 14
In the SDCC Terminations section, click Create.
Step 15
In the Create SDCC Terminations dialog box, select the slot/port that had been the protect slot in the

linear ADM, for example, for Node 1, this would be Slot 1/Port 1 (OC-48).
Click OK.
Step 17
An EOC SDCC alarm will occur until an SDCC termination is created on the adjacent node.
Go to the node on the opposite end (Node 3 in the

Note
You can create the circuits automatically or manually. However, circuits must be protected. When they
were built in the linear ADM, they were protected by the protect path on Node 1/Slot 1 to Node 2/Slot
1 to Node 3/Slot 4. With the new UPSR, circuits should also be created with protection.
Deleting the first circuit and recreating it to the same card/port should restore the circuit immediately.
Step 20 Monitor your SONET test set to verify that the circuit was deleted and restored.
You should also verify that the new circuit path for the clockwise (CW) fiber from Node 1 to Node 3 is
Step 21
working. To do this, switch to network view and move your cursor to the green span between Node
1 and 3.
Although the cursor only shows the first circuit created, do not become alarmed that the other circuits
are not present. Verify with the SONET test set that the original circuits and the new circuits are
operational. The original circuits were created on the counter clockwise linear path.
Step 22 Go to the network map to view the newly-created ring.
Procedure: Convert a Linear ADM to a BLSR
The following procedures describe how to convert a three-node linear ADM to a BLSR. You will need a
SONET test set to monitor traffic while you perform these procedures.
This procedure is service-affecting.
