Dry DSL is very likely the same thing as 'Naked DSL', which just means<br>
that there's data, no voice. From the sounds of things, through some<br>
ISPs, you can get as much as 15Mb/s down that way.<br>
<br>
There's never going to be a guaranteed speed over a mundane copper<br>
pair that's above 128Kb/s, though I expect most ADSL customers could<br>
switch to 'SDSL', which appears to be unregulated T1 (which would get<br>
you something like 1.544Mb/s up and down, each).<br>
<br>
Anything beyond that is going to depend on how many thousands of feet<br>
your copper line runs before it reaches the telco's DSLAM.<br>
