Well, I'd guess that there would be less crosstalk in a couple of coax
cables running near each other. It really is the rest of the route that is
the issue though, the twisted pair from your house to wherever the
multiplexer is. If you are proposing coax all the way, then you are
suggesting a very big job in many cases. The small bit from the pole or
junction box t to your house is only part of it.
I always thought adsl was ab bit of a bodge in any case, trying to use
cables probably installed before the internet was even launched, for such
purposes. Brute force in both directions comes to mind!

As I understand it, ADSL signals are passed along the twisted pair (is
that right?) telephone cables which are the same used for voice calls.
At a much higher frequency, of course. I am also under the impression
that the length of this cable is critical for service quality and
overall data rate (apart from junction / joint quality).

Would using coax for the last stretch to the subscriber's premises
provide any better quality of service?

I only ask as my cable service uses coax and I wondered about the
difference.

Cheers,

David.
