Clear a Path Protection Force Switch
Step 1 In the CTC node view, click View > Go to Network View if this view is not already displayed.
Step 2 In the network map, right-click the span that you Force switched. Choose Circuits from the shortcut
menu.
The Circuits window is displayed.
Step 3 Choose Clear from the pull-down menu at the bottom of the window.
The Force switch is cleared.
Note Active circuits are displayed green in the Circuits window. Standby circuits are displayed purple
in the window.
Note If these circuits are configured for revertive switching, they will revert to original paths after the
revertive time expires. If they are not revertive, they will not move back unless you Force-switch
them back. If the switch state is clear, you can complete the “Force-Switch Path Protection
Paths” task on page 10 again to force traffic back to the original path.
Step 4 Return to the“Replace an OC-48 Card” procedure on page 8, or to your originating procedure.
