Das Video zeigt die Telefontechnik mit Stangenwählern
Les 'Andy' Anderson demonstrates a 7 digital call (722-5634) through Seattle's PARKWAY Panel Office (In service from 1923 - 1972). This historic Panel Office provided Seattle with its first dial tone and direct dial calling (no operator assist) in September of 1923. This video shows the call as it is set up from the Line Finder through the District and Sender frames to the Final Frame. The Sequence Switches are shown at each stage (you'll hear an overlap of sound).
