Isn't this entirely discounting the effect of the FEC?

Also, do we really have raw codec bits on those first few carriers, or is most 
of the first frame a convolutional coded version of those bits? It does not 
look right that FEC and data are shown separately. My impression was that 
Voicing, Fundamental Frequency, Energy, etc. were assembled into a bit field 
which then had golay coding applied to it, and then most of the first frame 
would be the golay code output.

If this is not the case, why not?

Thanks
