[comp.dcom.telecom] Tour of #5 Crossbar in Grade School

   I really enjoyed your article "My First Cutover".  My first tour of
a phone office was the brand new #5 crossbar office in Park Forest, IL
when I was in grade school.  Many things from that tour left indelible
impressions in my mind.  The busbars in the battery room in the
basement, the rotary dial combination lock at the employee entrance,
the paper tape punch for saving toll records, the trouble-report card
punch at the test board, and the sounds.

As we walked through the electro-mechanical "computer" designed to
last 40 years (John Higdon points out with the application of a lot of
contact cleaner), the clicking of the relays throbbed in waves which
seemed to receed to infinty.
