I like the way you put that, "isn't shared as much". All bandwidth is
shared (and it's better for you that way because it makes your service
cheaper). In the case of DSL you have two bottlenecks. First is at
Xmission's Internet links. If there isn't enough Internet bandwidth to
go around then none of Xmission's customers will get their full speeds.
The same is true of any ISP of course.

The other possible choke point is between the Qwest's DSLAM and
Xmission's router. That could be either between the DSLAM and Qwest's
aggregation router, or between said router and Xmission. Most likely
that would occur with a remote DSLAM that doesn't have enough bandwidth
back to the Qwest CO. It's not common but possible.
