Probably the Wellfleet BN series
(http://www.nortelnetworks.com/products/01/bnrf/index.html). Depending on
how big is big, it could be a BLN (5-6 rack units high) or a BCN (about a
third of a rack high). There were also older LN & FN models that I sorta
recall were VME-ish.
Should have one VME-ish (but not VME) card that plugs into the front, which
is the slot processor card (called a FRE), and one that plugs into the back
that has the ports on it. You could mix-n-match port cards & FREs. There
were FREs based on the 68020, 68030, 68040 and 68060.
Wellfleet got sucked up into Bay Networks which got sucked up into Nortel.
They still sell the things, as ancient as they are.
As far as MMUs, the 68020 FRE didn't have them, and the 68060 FRE uses
68EC060s (the version lacking MMU & FPU support). I don't recall how the
others were configured.
