said by patcat88:You have no idea what you are talking about. I worked on wholesale DSL for nearly a decade in SBC/ATT. The wholesale subscribers are handed off to the independent ISPs at the ATM level.
Wrong, it hands off at Layer 1, copper pair. Since in the USA almost all competitor ISPs must provide their own DSLAMs/termination modems. This isn't Canada where you get 1 fiber optic cable with all of your customers' ATM PVCs on it.
