I suspect that you mean "bits".

I think you mean "baud".

This is true of many higher speed modems today, although some are compatible
with other manufacturers, and some are not.

I haven't any idea who might be making (attempting to make?) a 50kbps modem
for public switched anlog circuits (ie, phone lines).  (If it's my employer, 
forget you read this.) Have you tried asking various manufacturers reps?
