based on the 7% overhead, the max is 1350 Kbps, with a dl speed of 174
the highest dl speed i have had is 156kB/s......maybe the bellsouth overhead is just more though...or maybe im just unlucky
*this is a bit off topic, but thanks to all the people that posted the dial up cablenut settings (my cousins dial up bandwith is now 102kbps/12.8kb/s)
