All of this being true, what's the next move? Where do I put my IP nodes?

I think that we can both live with your explanations. Another example of force-fitting pre-existing lexiconics into the realities of evolving optoelectronics.

Re: DSL Obstacles to Deployment DenverTechie and Thread, Here's my layman's view on DSL deployment problems. Please feel free to correct anything I said that is wrong. All this is from general reading only and I'm simply trying to put the pieces together(not easy!). Three things that telcos are stuck with in their LEGACY twisted copper pair network that are NOT compatible with DSL services: 1. Load Coils 2. Bridge Taps 3. Legacy DLC equipment To deploy DSL services to those customers already being served by any one, two, or three of the above, is a definitely "no go." They have to be removed. Currently about 20% of telco customers are currently hooked up via a load coil. 20% are hooked up by a legacy DLC. Bridge taps, I don't have the figure for? Keep in mind, some of those 20% customers I just mentioned, have both load coils and legacy DLC. Now consider the load coil aspect. Well the load coil is there because the copper pair needed a "boost" to begin with. So that means those customers are already located quite a distance from the CO. Remove the load coil, do nothing else and at best, those customers can only get low level DSL Lite services. The bridge tap is there so the telco can take one twisted pair and hit quite a few customers with one copper pair. So that again, is a no go for DSL. Each customer has to have their own twisted pair back to the CO or remote DLC. And, as I believe you have said before, all the older DLCs out there already, can't be upgraded to deploy DSL services AND also have a compatibility problem with what's currently sitting in the CO. So add these obstacles together, and DSL deployment gets complicated! My current gut feeling is the telcos are going to scrap all the equipment above(1, 2, and 3). Get rid of the old DLCs, load coils, and bridge taps. Access most customers via NGDLCs, and then blast ADSL, and higher(VDSL), speeds to them. Otherwise, telcos are major losers when they attempt to compete with AT&T / Paul Allen's HFC networks. Those HFC networks cover about 80% of the market the telcos will compete in. Thanks, MikeM(From Florida) PS Frank thanks for Denver's older compatibility link!
