The last time we had a Bay Networks salesperson visit he stated that MCI
(this was before the merger) was an all-Bay frame network.  Whether that
has changed or not, I can't say, but I can't see them ditching it all so

And yep, having one Bay router left doing frame here, I'd love to know
what the problem is.  In NYC recently, we've had tons of problems as Bell
Atlantic migrates from frame to "frame emulation" on ATM switches.
