I don't know about anything other than Qwest-land in Arizona, but we are 
seeing the few T1s that are still in service provisioned as you 
described: a 2-wire DSL connection, although not out of a local DSLAM.

I think it depends on your definition of the box that's being used for 
connections as a DSLAM.  It's certainly not the same traffic engineering 
as DSL, because DSL circuits are muxed at the DSLAM (at least in 
Qwest-land) and may or may not be subject to congestion when leaving the 
neighborhood remote terminal DSLAM.  We for sure NEVER see any 
congestion on the T1s that are being provisioned using DSL technology.

Now, whether that's the same chassis with engineering over an uplink, or 
two separate chassis in the same road-side wart for the two different 
services, that's a deployment issue.

In other words, I think you're right about the technology involved 
(DSL-ish 2 wire circuits) being used to deliver, but there's more to it 
than repair time SLA when it comes to selling the same 2 wires as DSL 
for $39.95 and T1 for $399.95.  (again, at least out here in the Wild West)

That being said, I think your fundamental point is likely correct, 
something well known to everyone in this business: the cost to a Telco 
to provide T1 service is not 10x the cost to provide DSL service at 
similar speeds, and when there is that much additional marginal revenue 
being generated, they are going to fight with politics, tariffs, and any 
other tool at their disposal to keep the additional revenue coming in as 
long as possible.
