RateFactor(7:0)
RateFactor(15:0) Controls the Peak Cell Rate of the queue. It is identical to the Rate
factor TP described in Section 4.2.2.5 “Programming the PCR
Limiter” on Page 109. The value 0 disables the PCR limiter, that
is, the cells from this queue bypass the shaper circuit.
For VBR shaping, this parameter is not used (overridden by the
parameter TP of the AVT table). However, it must be set unequal to
0 to enable VBR shaping.
