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.

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.
