Usage Scenario

After link faults are rectified, whether to re-block the ring protection link (RPL) owner port depends on the switching mode.

In revertive switching, the RPL owner port is re-blocked after the WTR timer expires, and the traffic channel is blocked on the RPL.
In non-revertive switching, the WTR timer is not started, and the traffic channel continues to use the RPL.
