It doesnt matter if its below that. Im just wondering what youd get if you paid for "Upto 8Mb"...

2.2 miles = 3.54 km


Then, from here:

http://www.skyuser.co.uk/forum/speed...explained.html

(aimed at Sky's LLU, but same principles apply)

"50db...................................3.6km..... ..................................6500kbps"

So, an actual line length of 3.6 km should roughly have a downstream attenuation of 50dB, giving a potential possible max. speed (subject to noise margin) of 6500kbps.

However, your actual line length will be longer than 3.54km, as that's just the straight line distance to the exchange.
