What bottleneck? Distance limitations aside for *DSL technologies, I think what we get where I am is more than enough for your average SME. 830Kb/sec upload speed is OK for 10 concurrent G711 calls or a few dozen G729 calls. My view is that if a business really does need more concurrent calls than that, then there are alternative technologies avalable which are more suited to the larger enterprise - SDSL where avalable, or traditional 2Mb leased lines, or 10Mb LAN extension type circuits. And lets not forget that the ADSL backhaul is a contended service (at least where I am). You're not going to get any guarantees all that 830Kb/sec is going to be avalable all the time, but where you are things may well be different.
