At present, we limit our routers to 12 56KB ports (on 3 SCI's) or 4 T-1 ports (on 2 MCI's) and don't believe we are suffering any bottlenecks. If we assume that we want to allow each T-1 the potential to run at full-speed, we're probably limited to 6 ports (6x1.5MB = 9MB) by the speed of the Ethernet - is this considered excessive? In the case of 56KB ports, I expect that we're more limited by physical space for appliques and cable routing than anything else - is that also a reasonable assumption? Thanks, --Vince
