- Thank you. An explanation that almost makes sense. Where were you when I
- was asking this question for a month to supra tech support?
-
- However, is there not a time when a retrain is important to do? And why
- would you restrict your own modem from doing this, leaving it dependent
- upon the remote modem to be one that does NOT restrict this?
-
- If there is no time that this would be useful, why is it an option at all?
