The availability distributions of an exactly determined number of subgroups has been derived for traffic streams of various classes. The determined distributions enable calculation of blocking probabilities in multi-stage switching networks carrying different multi-channel traffic streams by the effective availability method. The paper defines the components of effective availability and gives procedures for their determination in the case of multi-channel traffic. In this paper, two calculation methods are derived, one used for point-to-point selection, and the other for point-to-group selection. The results of analytical calculations are compared with the results of digital simulation of three-stage switching networks. The proposed formulae can be used in the analysis of isdn and ?-isdn systems.
