I hate those extremely irritating download sites...

A simpler place to access can be found at this direct link instead.

The document has been seen before on here - the graphs of distance vs speed are probably on the optimistic side; likely they don't take into account real-world deployments with significant amounts of crosstalk & interference.on non-perfect lines.

MediaFire seems to be okay, no download delay or 'encouragement' to pay for premium downloads. Wonder why it is not used more often...

Certainly wasn't on anything to do with Be. tongue

I remember vaguely posting something like this a while back.

I believe the current profile BT use is 8C.
