Absolutely correct, the SDSL gets you around a lot of the inductance problems with baseband T-1s.  For quite awhile now 
most carriers deliver T-1s using SDSL smartjacks.  Some are single pair 1.5mbps bidirectional and on longer circuits 
they use two pairs each running 768 kbps.  That technology is what DSL home service developed from and predates the 
ADSL standards which were create explicitly for internet users that want more downstream than upstream.
