Creating Linear ADM Configurations

b. Record the circuit information using one of the following methods:

–

From the File menu, choose Print to print the circuits table, or,

–

From the File menu, choose Export to export the circuit data in HTML, CSV (comma separated

values), or TSV (tab separated values). Click OK and save the file in a temporary directory.

See the “Printing CTC Data” section on page 2-29 and the “Exporting CTC Data into Other

Applications” section on page 2-30 for more information.

Step 12 Remove the STM-N cards that are no longer connected to the end nodes (Slots 5 and 13, in the example).

Step 13 In CTC display one of the end nodes (Node 1 or Node 3 in the example).

Step 14 Click the Provisioning > SDH DCC tabs.

Step 15 In the SDCC Terminations section, click Create.

Step 16 In the Create SDCC Terminations dialog box, choose the slot/port that was the protect slot in the linear

ADM, for example, in Node 1, the previous protect slot is Slot 5/Port 1 (STM-16).

Step 17 Click OK.

An EOC SDCC alarm will occur until you create an SDCC termination on the adjacent node.

Step 18 Display the node on the opposite end (Node 3 in the Figure 5-40 example) and repeat Steps 14 – 17.

Step 19 Delete and reenter the circuits one at a time. (See the “Creating VC High-Order Path Circuits” section

on page 6-2.)

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 5 to Node 2/Slot

5 to Node 3/Slot 13. With the new SNCP create circuits with protection.

Deleting the first circuit and recreating it to the same card/port should restore the circuit immediately.

Step 20 Monitor your SDH 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, display the 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 SDH 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 Display the network view to view the newly-created ring.

Procedure: Convert a Linear ADM to an MS-SPRing

Caution This procedure is service affecting.

Caution Always wear an authorized electrostatic discharge wrist band when removing or installing ONS

15454 SDH cards.
