6.4 Viewing Bundle Intervals Statistics
If more than one measurement interval has passed since the IPmux startup or
reset, you can view a selected 15-minute interval or cumulative totals of the data
from the previous 24 hours in a graph or a table.
Statistics from previous intervals for a specific E1/T1 or E3/T3 port can be viewed
in list or graph form.
 To view a list of statistics from previous intervals:
• From the Bundle Connection Statistics Table (Figure 6-2), click <Bundle
