You only explained how *theoretically* that long-range DSL speed could be such-and-such megabits transfer speed, but perhaps you should touch on the real-world performance and costing model that various Bells have adopted to service and bill the consumer.
Seems that the last I heard, the emerging 'LD-DSL' (Long-Distance DSL) that PacBell was offering was a pathetic 128kbps symmetric xfer rate (up/down) for $120/month.
Considering what you said earlier about the amount of bandwidth that can be given to a consumer normally out of the 20,000' range of a telco station -- don't you think that giving them 1/10th the speed at 5 times the normal price is a RIP OFF?
I'll have to reread the articles I saw in OPT to verify.
There is a new company I know of that has just started their first residential rollout for broadband, which as it happens doesn't use the telco last mile (or anywhere in their transcontinental network). They have a 20,000' range also, and for a similar price the smallest service they deliver is 1-Mbit symmetric and they do it at a profit. This is the kind of competition the telcos really need -- there is hope yet.
