4.3.9.1 RF Switch Switching Criteria
Switch from primary to secondary:
When the primary RF input drops below the user defi ned threshold and the secondary
RF input is above the user defi ned threshold, the optical switch position moves over to the secondary optical power
immediately.

When the primary RF input is above the user defi ned threshold for one second, the
RF switch recovers back to primary position.
The RF switch position is persistently stored and the unit that recovers from power cycle will restore the RF switch initial
position according to its persistent value. The factory default is primary.
