15+ Mbps over T1?
An analog voice line (for telephones) with a normal modem can't exceed 53.6K (FCC law, but I think ~56K is the max people have managed anyway). DSL lets you get at least ten times that much, as much as 1.5 Mbps on a single line. (Actually, I think 1.5 isn't close to the max, but few places exceed it.)
A T1 is an analog line, is it not? (And a DS1 is the digital equivalent?) And you can get 'phone' or 'data' T1s -- a T1 can carry 16 (?) phone lines, or 1.544 Mbps (data).
So, couldn't one, in theory, split the T1 out into 16 phone lines, and run a DSL line on each one, at 1.5 Mbps each, giving them... 24 Mbps? I get the impression it can't (otherwise this technology might have become more mainstream?), but why not?
