The AT&T 3B20D computer is at the heart of some ESS made by AT&T.  There is
a lot more hardware to an ESS than just the computer, though.  The 3B20D
does run a release of the UNIX system, called UNIX/RTR (for Real-Time Reliable)
which is planned (I think) to be upgraded to SVID compatability some time.
The 3B20D and UNIX/RTR are not generally available except to RBOCs (Regional
Bell Operating Companies, the "baby bells").

That's about all I know, as I'm not in the switching area.
