This read-create Integer32, ranging 1 to 60 minutes or 0, sets how long to wait before reverting to the working facility once it's healthy again, applicable only when cmFacProtGroupRevertive is set to revertive. It acts as a hold-off timer that prevents traffic from flapping back to a link that might still be intermittently faulty. For example, a WaitToRestore of 10 minutes means the group waits ten stable minutes on the just-repaired working fiber before switching traffic back to it.
