WARNING: Better copy needed! OCRed years ago from borrowed originals with software that replaced questionable text with "its" best guess. New text is in a different font than the original image. We found at least one date that says 1984, but was probably originally 1934. Still worth preserving as is.

"Volume II contains a series of typical circuit diagrams. These are drawn in the simplified style which is used in teaching the complex 'Common Control' switching systems now in current use. This method makes use of sequence charts and operational sketches, and this volume contains a chart and sketch for each of the typical circuits."  Contributed by Steve Cichorsky. 

Legends for the training book produced by a New Jersey Bell employee that contains schematics and sequence charts for circuits encountered in a 355 Community Dial Office (CDO).
