Pagination or Media Count:
Evaluation of the error performance of data transmission systems faces problems because the error incidence does not follow conventional statistical laws for random occurrence. It has been found to follow hyperbolic statistical laws reasonably well, and these can be used as a guide to measurement procedures. A brief review is given of the Poisson and hyperbolic laws and their comparison with experience from rather varied sources. Some analysis is presented of the error incidence and grouping which occur during periods of poor operation, and the influence which these distributions have on the organization of measurement plans for the obtainining of significant results. Possible alternatives are suggested for characterizing error performance to the long-time average error rate commonly used.
