Hi folks:
This is not strictly a study question, but it might help even those that only
interested in study to think this one through.
I have a 3662 configured as a NAS with (a t1 pri + mica modems). Almost
everybody who dials in do so using regular pots lines. It looks like no body
ever get connected over 43K. I upgraded the portware to latest, it helped a
littele bit, but not much. Some are now connecting at 48K. If I remember
correctly, theoretically we should be able to connect at up speeds upto 53K.
Is there any suggestions on how to tune the modems or config to achieve this?
here is an excerpt from my config:
