We were invited recently to make a presentation to the Board of Directors of the American Telephone and Telegraph Company on the "Evolution of the Switchboard." The talk was accompanied by thirteen 35-millimeter slides, using color wherever possible, Starting with a diagram showing why a switchboard is required, various historic types of boards were discussed and illustrated from the first commercial one at New Haven through recent Traffic Service Position installations.

In order that the Directors might observe the TSP at first hand, the meeting was held at the headquarters of the New York Telephone Company. Subsequent to the meeting and the presentation, a brief tour was conducted. First an existing 3CL type office, soon to be replaced by TSP, was visited. The Directors were then taken to the TSP office where the Chief Operator demonstrated the operation at the training position using a specially prepared training tape.

Includes operator speed of service (Slide 8).
