Denver Techie: Thanks for your response. Specifically, what DLCs are now available in the marketplace to extend the telcos digital network to "remote" locations from the CO? Last time I talked to PacBell, I was advised of a PairGain box over in the next canyon (Benedict Canyon) that was installed to server a gated community because of "perceived demand" for T-1 access. At that time the rep I talked to was unaware of any present technology extending the range of ADSL. I always had a feeling that if a DLC existed for T-1 delivery, a DLC designed to extend DSL wouldn't be far off. lml PS Have you ever visited the DIMD Yahoo thread? I came across of very knowledgeable guy from Colorado on that thread who was very versed in local loop technology. You him?

Denver Techie ... NGDLS "out there" now? Commercial products shipping with general availability? Products that have solved the problems of high power dissipation in DMT ADSL? Environmentally hardened DSLAM and card products designed for integrated operations with shipping NGDLC? Products that are highly likely to provide the features and functionality that will eventually be required under future FCC unbundling rules for xDSL provisioned by ILEC network operations? My sense has been that the best a LEC could do to solve these problems was bolting a more or less proprietary DSLAM or remote access multiplexer onto their DLC system, perhaps sharing an existing enclosure, and plugging the backhaul data transport from the back of the DSLAM or RAM into the multiplexer that feeds the DLC system. Not integrated by any means, but it could certainly be made to work. Such an implementation would probably not be as cost effective as a more integrated approach some day with lower-power remote circuitry that can be fitted more densely into a smaller enclosure that needs less space-consuming battery reserve,but who wants to wait that long? I have been curious what USWest is deploying for extending their xDSL service to customers behind DLC. Their announcements did not state. Perhaps you can enlighten us as to whether USWest came up with a more elegant and economical answer than I describe? A serious deployment of this kind sort of shows ones hand insofar as the current CC docket 98-188 Advanced Services Regulation NPRM. It would seem to embrace a set of rules for ILECs provisioning xDSL services from their network (i.e., not from a separate subsidiary) -- rules that have yet to be written, and which may be very ugly indeed. You have to take your hat off to a company like USWest with such a DAMN THE TORPEDOES philosophy behind their actions and investments. Admire, but not necessarily invest in ...
