To make things short...both parties are right here, you CAN produce longer
distances through signal modifiers at certain locations, but copies of
copies are always less quality than the original.
You have to look at the physical side of things...which, most importantly,
is copper wire, not stranded copper wire. If you have stranded wire in
your home or business, then you must have some enormous monetary resources.
You also have to take into account the Fiber/Sonet side of things between
differing Telco's and how effectively they implement Sonet rings, which,
I'm sorry to say, is pitiful for the most part.
I know this is less than informative, but I'm not about to hit low-level
detail on a mailing list, it's just not the thing to do. But, this should
make some of you look at what you are implementing! As I said before, ADSL
will die out or at least fizzle to a close end.
