Erlang B is a very popular formula for trunk sizing. For certain sizings in COs, Erlang-Engset is used, since the number of subscribers is limited. André Girard, Routing and Dimensioning in Circuit-Switched Networks, Addison-Wesley Publishing Company, New York, 1990 is highly recommended since it addresses major analytical approached to designing voice public switched networks.
