Sorry sunray - I spent years on a network with a T1, then Fractional T3, then T3 - that site is just plain wrong.  T1 is 1.544 Mbits up AND down.  TOTAL BANDWIDTH is 1.544 Mbits.  Meaning if you upload and download at the same time, you'll get 772Kb each way.  T3 is roughly 35x that fast - 45 Mbits.  

a T1 is 24 channels of 64Kb - or 24 Phone lines - or 24 low speed ISDN lines.

I think that was a dumb mistake.. Should have concentrated more.. I have always learnt to do multi-tasking but i guess I do it right all the time.

thanks to both
