What I was saying was that I dont thing unix can route a steady 86Mbs data stream, so a full T3 on a unix box may very well be overkill. > >Cool, do it :-) The harder you push, the more likely it is someone will >take up the challenge of how to route more quickly. Gee...what I was hoping to get is what people need.....is there a substantial fractional T3 requirement? or does everyone need/want full T3? Would anyone buy a 32Mbs card, or is it a waste if it doesnt to full t3? It seems that there should be a market for relatively low-speed fiber....increasing the clock rate as you need bandwidth. 20 T1s is a lot of bandwidth. Dennis
