FWIW, I can't confirm this at this second, but I believe that at least the cisco 7200 series routers have a three PCI bus backplane. And it is claimed to support an OC-3c VIP2 port adapter, although I haven't put mine in action to try yet (and when I do I won't be running anywhere near 155 Mbps anyway). A single VIP2 port adapter can only connect to one of the three buses, so presumably cisco believes that PCI is up to the task. I don't know what the clockrate is, and I don't know if it is 32-bit or 64-bit.

I certainly think that an OC-12 card would be overkill though. I'm also wondering why someone who can afford an OC-x would be trying to save a couple bucks by using a PCI-based router. Once you get into this type of bandwidth, I think a bus becomes a serious chokepoint.
