Amen, DJ on that one.

The Kennedy Center for the Performing Arts in Washington, DC pretty much took most of my hairline. 38 separate closets, main frame room the size of a three-car garage (shared with ATT techs as a field office for them), all 1A2 and Tone Commander Centracom behind Centrex, 26 gauge house cable, 144 separate intercom systems, lamp extenders, you name it. Key equipment for a department with 30 phones was located in a closet across the building two floors up because there were slots available there! UGH.

You want to talk about ring transfer keys on a diode matrix? I believe that they invented this requirement there.
