The shaded area in Fig.9 represents the restrictions to the
transfer characteristic of a frame. The characteristic may
not cross the shown upper limit of the shaded area in order
to prevent input buffer underflow and/or overflow.
The slope of the upper limit is determined by the sample
frequency as shown in Table 5.
