In the second step, the reallocation of channel 5 is attempted. Channel 5 has a failover rate
of 18 timeslots. . The number of free timeslots is 16, so the system begins bumping low-
priority channels beginning with channel 1 to claim 6 more timeslots. Together with the
original 16 this provides 22 timeslots, sufficient for channel 5. After channel 1 is bumped,
channel 5 is reallocated to Link A, leaving 4 unused timeslots.

In the next step, the last high-priority channel is channel 16, which requires 18 timeslots for
backup. There are only 4 unused timeslots from the previous iteration, so the system must
again look for one or more low-priority channels to find the additional 14 timeslots required.
Channels 7 and 8 are bumped to yield 24 timeslots (channel 7 alone is insufficient). Once
channel 16 in reallocated to Link A, there are 10 timeslots remaining.
