I am looking for a summary of the various methods that commercial manufacturers have used to implement pseudo-V.32 modems. Specifically, I want to know Trellis shortcuts, different constellation mappings, unusual scrambler polynomials and full duplex techniques used to avoid echo cancellation. In a nutshell, what the manufacturers have done that would make thier modems non CCITT compatible. Any idea of how popular any of these modems are (how many have sold, what countries they are used in) would be helpful. ********************************************************************** Jonathan Whitcomb UUCP: <...!mcnc!aurgate!whitcomb> (919) 850-6231 "Uh-oh, uh-oh, there's panic in the world" Raleigh, NC -Bill Nelson
