5 – Reference redundancy function
AUTO SW (automatic switching) mode
In this mode, after the unit has switched to the secondary
reference clock, it will not switch back to the primary reference
clock automatically when the primary reference clock recovers.
If the secondary reference clock is lost, it will switch back to the
primary reference clock (if it is available).
After the unit has switched to the backup reference clock, it will
switch immediately to the primary reference clock or secondary
reference clock when it recovers.
