- Well, let's consider the following:
-
- V.Fast is pretty much illegal outside North America due to excessive RF
- generated by this modulation. I doubt you're doing much international
- calling, so I'm sure this is a non-issue.
-
- V.34 is an ITU standard, which means EVERYBODY around the world accepts
- it. V.34 is NOT compatible with v.34, and everybody is moving away from
- v.34. That alone is a good reason. For example, you dial v.34 into a
- v.Fast, you get 14.4(v.32bis): highest common denominator. V.Fast is a
- Rockwell protocal, which pretty much says "avoid me as you know it will
- never get ITU acceptance".
-
- If that's not enough for you, v.34 is a much more robust protocal, quieter
- and more dynamic. I know v.Fast allows some train-up should the line
- degrade and then improve. v.34 will adjust up and down much quicker. While
- this may be an insignificant amount of time to the average user, do you
- really want to pay for time wasted during re-training with v.Fast?
-
- If you need or want more technical, don't respond directly to this
- address(although it will get you a direct response anyways), respond to my
- business account: chris@lanets.com, as I give priority to e-mail sent to
- this account.
