I just talked with a vendor last night who sells modem servers which use 486/66 boxes with a 16-port BOCA card. They use FreeBSD as the OS, and according to the vendor he was running 9 lines at a full 115K baud when we has talking to me w/out a hiccup. I would think it might be a stretch to run 16 lines at a full 115K/line full open with a 486/66 all the time w/out some SIO overflows (which are taken care of in SW, but slow the line down none-the-less). However, if I were an ISP, I would *seriously* look at a FreeBSD box since they are cheap, and do you ever rarely get more than 3-4 users running flat out at any one time. Most traffic is 'bursty' with the line being idle most of the time. With that in mind, you *may* be able to run a 2*16 port modems on a 486/66 box with little to no problems, but you're probably stretching the hardware to it's limits with no room to spare. Upgrade the CPU to a P90/100/120 and you might pull it off.
