Setting Clock
Source
Clock source comes from BITS (STS-1 cards) and Interface Groups.
There are 13 possible priorities. When present, priorities 1 through
4 are used for STS-1 cards and 5 through 12 for interface groups.
Priority 13 is reserved for system clock and is not user-
configurable.
When the revertive behavior is selected, it takes place across all
priorities. For example, priorities 1 and 2 lose the clock, and
priority 3 takes over and is actively driving the bus. When priority
1 regains its clock, then priority 1 will then take control of driving
the bus.
