The only reason it works is because you are buying dry copper from point to point and putting a special box on each end. An ISP has a choice at that point of either a) co-locating at the CO and putting a multi-port xDSL unit there and hauling the bandwidth back to their nearest POP that can handle it, or b) within the distance limitations, buy two point-to-point copper lines, one to the customer, one to your POP. In the latter case, you are using the CO as a "patch panel" and just twisting the two lines together so you can aggregate the bandwidth with cheap copper vs. expensive T3s... None of the explanations I've heard yet mention anything about the CO switch, as all the xDSL (except for IDSL, which I don't yet comprehend) methodoligies don't touch a switch. You're only in the CO to pick up the wire. Charles
