New Equipment for Experiments on Data Transmission and Error Analysis

This paper describes the test equipment which was used jointly in 1959 by Post Office authorities and IBM for evaluation of the data transmission feasibility over European telephone networks. A summary of the results gained is displayed and demonstrates the feasibility of data transmission even if many problems are still to be solved. In the second part of the paper a method for recording and analyzing the errors is explained briefly. This method uses a conventional way of programming a computer and will be used in the future for statistical studies on error distributions.
