It's not TI it's T1-T3. T1-3 are basically super dedicated lines mainly used for schools and businesses. The speed ranges from 2mb(T1) to 135mb(T3 Dedicated).

Myself am on something like OC-256 which is an internet backbone. The speed to my internet is 700gb/s.
My average download speed is about 10-20mb/s.
How much does that cost you?
