tabs.
b.
From the Protection Groups list, choose the group you want to delete. Click

disruption.
Note
Deleting a 1+1 protection group may cause unequipped path (UNEQ-P) alarms to occur.
Step 7
Physically remove one of the protect fibers running between the middle and end nodes. In the
example, the fiber running from Slot 4/Node 2 to Slot 4/Node 3 is removed. The
corresponding end-node trunk card will display an LOS alarm.
