Are Phone pics helpful to anyone?

I notice the phones also. What about the phones in movies from the 70's and early 80's.

Never worked on a 25 pair phone [each phone had 50 wires going to it], or any single line phone, only business phones using a KSU. The Intertell ESP phones was 4 pair.

Yeah the old 6 button phones had 25 pair cables, the 10 buttons needed a 50 pair and then there were the 10 button phones with the side cars that required 100 pair cables.

A lot has changed since I started installing phone systems in 1984.

Premier/Intertel ESP's are 3-pair/6-wire (with one pair reversed or you'd pop the fuse on the STN card), I've got 3 cabinets sitting in the closet along with a heap of 24-button keysets w/LCD's. The local carrier (Sprint) was installing them all over the place when they were new. One of the Sprint technicians was friendly with us and would broker a deal for us when other businesses upgraded, we bought their old Intertel systems for spares. Finally upgraded 3 years ago (yeah we got our money's worth out of the old ESP system).
