Something like that.
DS0 - the digital band for 1 POTS line line
(8bits wide, 8KHz, 1 bit is used for control every 6th
frame, hence the 56Kbps theoretical modem limit)
DS1 - 23 (or 24, I'm not sure and my notes are at home) DS0s
T1 - how to carry DS1 over electrical wire
DS3 - several DS1s
T3 - how to carry DS3 over electrical wire
OC3 - Optical link, has the capacity of a _lot_ of DS3s!
(wouldn't it be nice to have that at home?)
I studied this stuff last quarter :-). I think networking is really
neat. I didn't memorize (other than DS0/DS1) what the sizes of the
links are and my notes are at home while I'm on co-op.

Ditto. Debian is not an ISP and has no lines to lease to you.
Leasing a line is also very expensive (unless you are a large
organization that can afford it and needs that kind of bandwidth).
