I've said it many times, but that's a sad situation for backhaul. If there are only 20 customers and they all have 6mbps and are normal internet users, a DS3 would be okay, as it's unlikely they'll all be using full pipe at the same time. But an entire area being fed off T1's is ridiculous. I say ridiculous but I've seen it here on the forums more than once. I want to say Hank also has/had that problem.
I have always been able to pull at least 5mbps of my 6mbps, so either they don't have many DSL customers here or there's enough backhaul.
Living that close to a major metropolitan area and having any less than 10mbps is ludicrous. I say less than 10mbps is ludicrous, but I lived with 768k up and down for about 2 years before Frontier brought in DSL.
