That particular combination can't saturate it. In fact, even if you fill the PCI bus with 4xT1 cards, you have plenty of bandwidth: 4XT1 = 4x(1.5Mbpsx2) = 12Mbps 4 cards@12Mbps = 48Mbps 1x 10/100 = 100Mbps Total=148Mbps. PCI can (and does) deliver up to 500Mbps. The real question is when does FreeBSD get in the way... Tony
