Pat and Frank, I'm going to try as best as possible to stick to technical facts and public knowledge and not engage in conjecture. I know you'd like my opinions, but I'll withhold them for now. Frank: the open access issue with AOL etc, is a hot topic and I'm not in a position to make a comment at this time. Pat: I can't speak for what vendors may or may not do with their products, or may or may not claim as their advantage. What I do know is that to pass DOCSIS 1.1, you have to first be certified at DOCSIS 1.0 then DOCSIS 1.1. Therefore it follows if DOCSIS 1.2 is built on DOCSIS 1.1, you have to be certified at DOCSIS 1.0. I am not sure if CableLabs will allow any other certification paths than what the above logic presents. I have observed that CableLabs does feel that a certified modem shipped at 1.x, would work on version 1.x, 1.x-1, etc CMTS. It's the only way they can guarantee that a purchased modem will be universally deployable in the U.S. Mark
