Re: DSLAMS in MDUs ... Multiple Dwelling Units usually seem to be a precursor for new consumer services, probably because of the early opportunity for scale economies. My question with your post goes to the purpose of any DSLAM/ATU-R/ATU-C equipment in the MDU serving topology you cite. It seems to me that the DSLAM, etc. is redundant in such a serving arrangement. If you bring T1s or better into a building by whatever means from whomever, and you want to share that bandwidth among clients in a building, why not just feed a router with the backhaul bandwidth and connect customers with ethernet, Tut, or whatever? If it's a really a big building, wouldn't you find a serving topology perhaps with multiple routers/ATM switches that is cheaper than a DSLAM/xDSL serving arrangement? Just like business serving arrangements today?

I believe that ADSL is much more appropriate for serving dispersed residential customers than highly clustered ones, but that caveat only applies if the clustering occurs predictably and with quick high penetration. That could certainly be the case with a building that advertises and promotes its web-friendliness -- certainly many residential and business buildings do so today.
