Non-revertive switching
In non-revertive switching, there is an active and standby high-speed line, circuit pack,
etc. When a protection switch occurs, the standby line, circuit pack, etc., is selected
causing the old standby line, circuit pack, etc., to be used for the new active line, circuit
pack, etc. The original active line, circuit pack, etc., becomes the standby line, circuit
pack, etc. This status remains in effect when the fault clears. Therefore, this protection
scheme is “non-revertive” in that there is no switch back to the original status in effect
before the fault occurred.

Non-synchronous
