	port. A Force ring switch will switch traffic off a span if there is no signal

Tools/Equipment	None
Prerequisite Procedures	DLP-F181 Log into CTC, page 16-34

Caution The Force Switch Away command overrides normal protective switching mechanisms. Applying this command incorrectly can cause traffic outages.

Caution Traffic is not protected during a Force protection switch.

Step 1 From the View menu, choose Go to Network View.

Step 2 Click the Provisioning > MS-SPRingtabs. Select the MS-SPRing.

Step 3 Click Edit.

Step 4 To apply a Force switch to the west line:

a.Right-click the west MS-SPRing port where you want to switch the MS-SPRing traffic and choose Set West Protection Operation.

Note If node icons overlap, drag and drop the icons to a new location. You can also return to network view and change the positions of the network node icons, because MS-SPRing node icons are based on the network view node icon positions.

Note For two-fiber MS-SPRings, the squares on the node icons represent the MS-SPRing working and protect channels. You can right-click either channel.

b.In the Set West Protection Operation dialog box, choose FORCE RING from the drop-down list. Click OK.

c.Click Yes in the two Confirm MS-SPRing Operation dialog boxes that appear.
