In addition, a dedicated T1 or fractional T1 is supposed to be much more
reliable than DSL. The telco will typically treat a DSL outage like a voice
line problem (up to 5 days to fix it) whereas a T1 outage is supposed to be
addressed immediately. That's why they charge the big bucks for T1 service.
You can save some money if fractional T1 is available in your area. A
fractional T1 is a T1 circuit but the total bandwidth available is less
than 1.5Mbs. (A full T1 is made up of 24 separate 64Kb channels.)
We use a full T1 for web hosting and a synchronous 1.1Mbs RADSL circuit for
web browsing. We plan on replacing the RADSL with cable shortly because the
bandwidth should be much higher and the cost much, much lower. Before we
dump the RADSL we'll do some very specific testing to make sure we aren't
going to get inferior service.

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.
