I've never heard of a 2500 :-), but the 2400 MNP is supposed to be upgradable to a Plus. My local sysadmin recommends: 2400 baud with V.22bis with MNP2-4 for error correction and MNP-5 for data compression. Will I get all of this with the Supra? yeah. Btw, I believe all commercial 2400 baud modems are V.22bis. Raul Rockwell
