I don't work with the switch itself, but I work with a bunch of ISDN/BRI and PRI customers in the DC metro area that are still using them. Where I live in NC, even the local independent telco uses the 5E and remotes just about everywhere. They were put in when Sprint owned the territory in the late 80s. In this area, I only work with them for ISDN/PRI and POTS customers, but they sure are reliable from a service and troubleshooting perspective. I'm going to hate to see them go.
