and the maximum deviation from the median is less than half of the total TX jitter budget
collected over any 250 consecutive TX UIs. It should be noted that the median is not the
same as the mean. The jitter median describes the point in time where the number of jitter
points on either side is approximately equal as opposed to the averaged time value.
