These pictures (and there are pages and pages of them) may have been linked before in The Telecom Digest, I personally can't remember.
A fellow telecommunications veteran sent this link on to me. It looks like people have contributed pictures from their photo albums covering years and years of telephony history. Included in the photos are a myriad of products, schematics, system switch locations and system feature layouts.
Here is the link to the starting page. Hope they bring back memories to you as they did for me!John ______________________________________ John Stahl Telecom/Data Consultant Aljon Enterprises
