JL> V.Fast is the "working name" for the proposed V.34 standard.

Which is saying precisely what I said in different words.

RS> V.FC, V.Fast Class, is Rockwells own standard which attempts to get

JL> Yeah, but the question still remains: - Will V.34 be backward

Depends on what you mean. I think its unlikely that the full technical
detail of V.FC will actually be included in the full formally ratified
V.34. But thats not to say that a particular set of modems which claim
to implement V.34 wont also operate with V.FC modems. If you mean the
last one, yes, that is what I think is most likely.
