-3

A T3 is rated for 45Mbs.

What is the expected run time upload and download speed of a T3 assuming both are happening at the same time?

  • So I get two downvotes for what is logically a reasonable question. The downvoters didn't leave a comment on how to improve the question. [I posted this related thread on Meta](http://meta.serverfault.com/q/5272/51457) – makerofthings7 Mar 01 '13 at 18:04
  • The hover text of the downvote icon says `"This question does not show any research effort"`. I'd say this fits the bill. There are two possible options: half-duplex, meaning you'll top out at 45Mbps or full-duplex, meaning you'll top out at 90Mbps. It's trivial to research which of those two categories a T3 falls into on your own. – MDMarra Mar 02 '13 at 03:29
  • @MDMarra I'll take my lumps (in downvotes) and leave this as a signpost for anyone else who needs to ask a simple question like this, and the expected response. – makerofthings7 Mar 02 '13 at 03:53

T-carrier circuits are full-duplex, so total aggregate theoretical bandwidth would be 90 Mbps.

45Mbps is 45 mega bits per second, for an approximate value of bytes per second of user data (excluding protocol headers and such) divide by 10, so this would give maximal 4.5 megabytes per second.
