- Wrong.
-
- Please re-read the articles I've posted about this. They explain
- that the modem will ALWAYS initiate a retrain if a rate renegotation fails or
- if the line conditions degrade enough to require one (ie. the EQM exceeds the
- retrain threshold).
-
- The %E and %G options control what is method is used first when
- adjusting the data rate based on the current line conditions, either a retrain
- or a rate renegotiation. If rate renegotiations are enabled the modem can
- and will initiate a retrain.

- Exactly what are we in denial about? The modems do exactly what you
- believe they should do. This is the same behaviour every Supra modem has had
- since our first V.32bis product, default to using rate renegotiations and only
- retrain if a rate renegotiation fails or the EQM exceeds the retrain
- threshold setting. This is the exact same behaviour every other V.34
- modem I've tested has.
