As for ATM... The part that totally baffles me about the use of ATM on xDSL lines is that I have never, ever, ever seen an xDSL line carrying more than one ATM VC. OK, there may be someone out there who has set up a configuration like that just for fun, but 99.999% of all ATM'd xDSL lines out there carry a single PVC at 0*35 or 0*38.
Multi-PVC is used (in the context of xSLAM<-->CPE), for example, for delivering IPTV+DSL. 0/35 and 0/38 are just arbitrary numbers, there are plenty of other random ones like 0/33 used by major service providers. Arguably your "99.999%" is way off.
