DSL is shared via frame relay down at the phone company.  If the 
frame-relay is not managed well in your  area (if they try to cram too many 
DSL user onto one circuit), it could affect the traffic rate 
tremendously.  When we first set up one of our DSL lines, the highest 
upload speed we could manage (using the speed tester at dslreports.com) was 
120.   We had to work with the ISP and the phone company for several weeks 
before the problem was solved.  After they tuned it (I assume they moved us 
to a circuit with less traffic), we could manage 600+ and 700+ at 
times.  This is on a line advertised as 768 max.    My understanding of 
T1's is that you share with nobody--it's guaranteed bandwidth.  DSL is way 
far cheaper, but you'll have to monitor it to make sure you are getting 
what you pay for.
