Caution Traffic is unprotected during a protection switch.

c. Start CTC for the node that is connected through its west port to the target node. (In the Figure 5-33

on page 5-44 example, this is Node 3.) Click the Maintenance > Ring tabs.

d. From the West Switch list, choose FORCE RING. Click Apply.

Step 3 Start CTC on the target node.

Step 4 Click the Circuits tab. Write down the circuit information or, from the File menu, choose Print or

Export to print or export the information; you will need it to restore the circuits later. 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 5 Delete the circuits on the card you are removing:

a. Highlight the circuit(s). To choose multiple circuits, press the Shift or Ctrl key.

b. Click Delete.

c. On the Delete Circuit dialog box, click Yes.

Step 6 Delete the SDH DCC termination on the card you are removing:

a. Click the Provisioning > SDH DCC tabs.

b. From the SDCC Terminations list, click the SDH DCC you need to delete and click Delete.

Step 7 Disable the ring on the target node:

a. Click the Provisioning > Ring tabs.

Step 8 If an STM-N card is a timing source, choose the Provisioning > Timing tabs and set timing to Internal.

Step 9 Place the ports on the card out of service:

a. Double-click the card.

b. On the Provisioning > Line tabs in the Status section, choose Out of Service for each port.

Step 10 Physically remove the card.

Step 14 Follow the steps described in the “Setting Up MS-SPRings” section on page 5-25 to reenable the ring

using the same cards (in their new slots) and ports for east and west. Use the same MS-SPRing Ring ID

and Node ID that was used before the trunk card was moved.

Step 15 Recreate the circuits that were deleted. See “Creating VC High-Order Path Circuits” section on page 6-2.

Step 16 If you use line timing and the card you are moving is a timing reference, reenable the timing parameters

on the card. See the “Setting Up ONS 15454 SDH Timing” section on page 3-16 for instructions.
