My ISP grew up on Livingston Postmaster 2e & 3s.  I even had a Postmaster 4 for a bit.   Lucent swapped that out for an 
APX 8000.    I still have an Ascend TNT running the remainder of my modem pool.     8 Active users on it at the moment.

Recently won a state contract for IP services.  The very first order was for a chunk of dialup accounts so the 
Department of Conservation and Recreation could call in from their firepowers.

It just keeps chugging away in a forgotten corner of my datacenter.
