Hi Peter, Ultra-DSL....ever heard of it? 250Mbps @ 1800 feet, 100Mbps @ 3500 feet is the claim. Appears that it is turbo-coded with some advanced crosstalk cancellation and 400mW transmit power books.nap.edu Google yields nothing about it that I could find. Probably costs $2000 per subscriber, and only about 15% of copper loops would meet the distance limit. Not clear whether it is just simulation results or prototype or what. John Cioffi (father DSL [he's the one to blame, Elmat]) was the lead contributor to that section of the book, and the list of reviewers is quite a who's who of the technology world. So it at least had some credibile eyes looking at it. Would require lots of new-bury copper to be useful on a widespread basis anyway, so its real prospects are grim regardless of whether it could be made cost-effective.
