You are leaning against the winds of change,watch out the Tsunami of fiber is going is going to choke you with a copper line. Hmmm, sounds like an HLIT salesman! <ggg> I hope your right Hiram, I'd love nothing more than the Cable Co and the local RBOC competing. Also all the affluent neighborhoods in my area that can't get DSL will sign up to cable in the masses. DSL does not cover the majority of where the money is in my area. @Home has a wonderful opportunity, I hope they take advantage of it.

Hiram: As a correction, for VDSL you do not need fiber to the curb, but fiber to the neighborhood (about 100ft to the customer). The architecture is similar in many ways to HFC networks, which are hybrid fiber/coax. VDSl is in essence hybrid fiber + copper. The approximately 50Mb/sec it offers to customers is dedicated, and therefore far superior to anything cable modems have to offer, since each cable downstream channel will offer about 40Mb/sec as a shared medium. Also, when you say ADSL does not run over fiber, this is true, but all ADSL architectures aggregate ADSL signals over fiber (there was a nice article on this topic by George Hawley (sp?) in IEEE Communications Magazine about 2 years ago-- he is involved with Diamond Lane, I believe). As a general rule, I do not believe there will be one last mile solution which will dominate. My guess is that the 3 contenders for business users will be FTTC + fast/gibabit Ethernet, broadband wireless, and VDSL. For home customers, we will probably see a mix of cable, ADSL, and wireless by satellite emerge. Each of the proposed solutions have strengths and weaknesses. For cable the big cost is cable plant upgrade, which cannot be dismissed so easily. Similarly, FTTC is quite expensive. Best wishes, Bernard Levy

Hiram, I'm not trying to sell anything. I am providing answers to technical questions in an unbiased, semi-layman's terms to try to remove the hype from this area of technology. If we can all learn something and have some fun with it, that's the goal. I have no preconceived notions on ADSL vs. cable modems vs. wireless. Each has its strengths and weaknesses and we need to understand what they are to make better decisions. I don't have an "angle" other than education. I was asked what the theoretical vs. practical bandwidths of copper and coax are so I answered those questions to the best of my abilities. I don't really have any particular agenda to push if that is what you are getting at.
