Third, calculate it. Terabits or terabytes dont even come into play.
As far as T1's, T3's, and T4's they all exist as do T12's and everything in between. Its just the relative cost of tying up that many POTS lines into one user(or one network, like a corporation)
T lines are digital and use a certain nuimber of phone lines to transmit to the CSU/DSU which sends it to a router, which sends it to your PC via ethernet at speeds up to a gigabit. (remember guys if your NIC or cable cant handle it, **** it.)
T1 is 1.544mbps, T2 is twice that, T3 is three times that (6.5ish mbps) all the way up to 12, which would be 1.544 * 12. You figure it out. I've never seen any standard for anything past that - its too costly. Fibre is much cheaper to run that 8 tele lines for a T1 (24 for T3, 96 for a T12) because fibre can handle more than any signaling method we've come up with for it, including ATM OC-3072. And the only reason they have ATM OC's (ATM is the signaling type, OC is the fibre) is for a connection between routers that can handle it. Routers, those things that handle every last packet sent by every last user on the internet, can handle those speeds. You gotta remember thats everyones traffic on the internet those things deal with, every last packet.
and i agree with respawn, its all relative, someday we could laugh at an ATM OC3 because it takes 10 seconds to beam you up to your friends house, whereas ATM OC-3072 takes only half a second...
who knows?
