My question is about current ISDN cards (i.e. cardinal internals) as oppsed to isdn routers. I am getting an ascend router because I was told by numerous people that the latency (and lack of synchronous) communications [at least in the US] makes Terminal adapters and internal cards a low performance solution, My tests hav concluded that the latency across an isdn connection with a router is about 15ms (30ms ping) where as with a TA 50ms (100ms) ping is considered good depending on if you are going from TA to TA or TA to Router, I'd love to see an internal card that doesn't use 16550's that I can put in my freebsd machine and get good performance out of -- actually my idea would be an internal card that looks like an ne2000.. Maybye it already exists for use in the US but I have not been able to find any.
