Ok I am not completely certain of this but here goes anyway.
I believe that a T1 is a full-duplex full-time 1.5MBPS "bit-pipe"
connection.
Unlike DSL which is usually ADSL(asynchronous...meaning different upload and
download speeds), T1 is full bore both ways.
Also, every DSL contract that I have seen has a bunch of disclaimers
regarding the guaranteed speed....with a T1...you will receive a SLA service
level assurance that specifies the speeds, uptime and remedies(if downtime
occurs)
IMHO MCI(UUNET) is the best provider in the USA.
their support is incredible...I receive text messages to my cell phone when
a circuit goes down and voice messages to my answer machine.
Dave makes a good point regarding why you have throughput problems...it may
only be partially related to the DSL and partially to your server/network.
for stable, guaranteed connectivity, T1 is your best bet....BUT be prepared
for more complexity than you are used to with DSL...they'll be a router that
needs to be configured.
Just my $0.02
