This first took the form of "aDSL/sDSL" (asynchronous v. synchronous digital subscriber line) which originally had its origin in the longer loop length aDSL (and therefore the larger consumer base) the technology could provide. That advantage has long since reversed and aDSL now is effectively an artificial technical restriction, keeping upstream bandwidth speeds low and allowing internet service providers to charge business users more for sDSL, which is, in effect, the cheaper, better technology. To some extent this differential has been eroded, forcing providers to provide the same technology solutions and employ "use restrictions" based on "terms of service" agreements. -- [<a href="http://equityprivate.typepad.com/ep/2008/04/the-five-circle.html">The Five <strike>Forces</strike>Circles of Hell</a>]</p> </blockquote> <ul> <li>ADSL is effectively an artificial technical restriction?</li> <li>SDSL is the cheaper, better, technology?</li> </ul> <p>Can anyone comment on this? I don't understand the technology or infrastructure implications of ADSL vs SDSL today.</p> http://matt.blogs.it/entries/00002840.html
