I don't think there is specific reference code for this. However, if you 
read the appendix you will find it is just using a section of the G.729 
algorithm. You can lift suitable code out of the reference G.729 code. 
There are floating and fixed point reference codes for G.729. As far as 
I know, either could be the basis for a G.711 appendix II implementation.

G.729 is heavily patented. However, as far as I know none of that 
applied to the parts you need for G.711 appendix II. Of course, if you 
use any of the G.729 reference code you have copyright issues. For real 
world use you probably need to produce a clean new implementation.
