Just for random information. A T3 is the same as a DS3 and it is 28 DS1/T1s which are about 1.5mbps each (24 64Kb channels) and a T1's channel is also called a DS0, basically, a phone line.
OC is Optic Carrier, so it's fiber, and I think the highest they are at now is 40Gbps or something like that. I forget the number though I think it's OC750 or something like that. I saw that on a site and I said "wow!" My supplier has OC12 routers for 75,000 in case anyone needs one. Or you can go to a car dealer and get yourself a very nice car, your choice. 😀
