I do know that ZyXEL's modems are able to do real-time CELP using a 68000 processor. The low-end models can do CELP encoding at 9600 baud, and the faster ones do better-quality encoding (ACELP, I think they call it) at 19200 baud.
I believe that there is a DSP of some kind in there in addition to the 68000. Also, only their high end modems do CELP. The regular 14.4/16.8 one doesnt't.
