Abstract :
In a recent data transmission test, a method for visually evaluating the causes of errors was tried. Photographic reproductions of error messages were produced by the combined use of a magnetic tape recorder and a recording oscillograph. These were analyzed visually and the errors classified by cause into eight categories. In several of these categories, the fault lies in the terminal equipment, in the rest, apparently in the transmission channel. Examples are given of various types of errors encountered.
