I think I have a Wanic 500 around that I bought on ebay. Any support for those? I've got a driver for this card that I was sent by Imagestream, they got it from one of their developer/customers. It's for something like FreeBSD 4.9 or 4.3, I can't remember which. It will not compile unmodified on FreeBSD 4.11 Supposedly the programming docs for the chipset used on the WanIC 500 are only available under NDA, so without clear direction from Imagestream the driver would probably not be able to be distributed publically. I never signed an NDA, though. The best bet for current support for these cards is to use Linux, you will get plenty of support from Imagestream, then. Unfortunately this is a market where the few manufacturers of synchronous serial port chipsets - Hitachi, etc. - only have a handful of router vendors (like Cisco, etc.) that regularly buy these chipsets. The router vendors are faced with a shrinking market for these chips since more people are going to DSL and such rather than T1s and they don't want to see an upstart competitor take away business, so all of them are pressuring the chipset manufacturers to be very sparing on providing documentation to anyone else. Ted Or should I just make my BSD box ether to ether and sit a Cisco on top of it? Tnx.

It's a driver bug, the sr driver needs a rethink of it's buffer structures. also, there's a bug with the wanic 2 port cards that isn't present in the risecom/n2 2 port cards, they drop characters when both ports are active. With Cisco 1601's selling on the used market for $25 or so, there's little interest among the developers in fixing this. Also the wanic 4xx is no longer in production, another disincentive. It would be interesting benchmarking this with Imagestream's Linux-only drivers.

I'm using the sr driver netgraph, mpd, and pf with altq, since I want to do priority routing for some voip phones. It all works fine until the t1 gets busy, e.g., if I do a wget on the router, and which point it starts complaining about TX overruns and the traffic on the wanic stops. Any suggestions? The PC is pretty slow, and one thought is that I also have an old SDL RISCom/N2 ISA card which is slower than the wanic. Is that likely to work more reliably? Speed isn't much of an issue on a single t1 and yes, the PC is old enough that it has ISA slots.
