System processing when a fault occurs during the WTR time on an ASON network?

When a fault occurs during the WTR time, how the system processes a service is related to the service SLA but not related to whether the automatic reversion time is set.
For example, if the service is under diamond rerouting 1+1 protection and the protection trail is faulty during the WTR time, the ASON software considers that both the working and protection trails are faulty and therefore computes a new route according to the rerouting 1+1 protection mechanism.
If the service is under diamond non-rerouting 1+1 protection, when the preceding condition occurs, the service is directly interrupted according to the non-rerouting 1+1 protection mechanism.
