Further Analysis of Errors Reported in “Capabilities of the Telephone Network for Data Transmission”

The recorded error data from a field testing program reported on by Alexander, Gryb, and Nast have been further analyzed. New methods of analysis have given more information on the causes and nature of errors experienced by data in the switched telephone plant. The results obtained will enable workers in the field of error control to use the field test data more effectively. The ideas presented will be useful to designers of future field tests.
