This video demonstrates how a call was made from a 3-slot rotary payphone in the 1960's. It also shows the progression of the call through a Step-By-Step electromechanical exchange. The call reaches telephone number "Beechwood 4-5789", which was the title of a hit song in the early 1960's. Throughout the video, the chatter of an actual Step-By-Step exchange can be heard in the background.
