This book shows you how to properly select and use the major traffic formulas based on the Poisson, Erlang-B, Erlang-C, and Engset distributions. Computer program listings written in BASIC are provided for these traffic formulas, for crossing between table values that are not represenative of the system being analyzed, and for detemining more precise values for a specific application.
