Linear ADM Configurations
See the
“Printing and Exporting CTC Data” section on page 2-41
for more information.
Step 12
Remove the OC-N cards that are no longer connected to the end nodes (Slots 1 and 4, in the example).
Step 13
Display one of the end nodes (Node 1 or Node 3 in the example).
Step 14
Click the
Provisioning > Sonet DCC
tabs.
Step 15
In the SDCC Terminations section, click
Create
.
Step 16
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).
Step 17
Click
OK
.
An EOC SDCC alarm will occur until an SDCC termination is created on the adjacent node.
Step 18
Go to the node on the opposite end (Node 3 in the
example) and repeat Steps 14 – 17.
Step 19
Delete and reenter the circuits one at a time. (See the
“Creating Circuits and VT Tunnels” section on
.)
Note
Deleting circuits is traffic affecting.
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.
Step 21
You should also verify that the new circuit path for the clockwise (CW) fiber from Node 1 to Node 3 is
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.
Caution
This procedure is service-affecting.
Caution
Always wear an authorized electrostatic discharge wrist band when removing or installing ONS
15327 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.
