A model of an overall telecommunication network with virtual circuits switching, in stationary state, with
Bernoulli-Poisson-Pascal (BPP) input flow, repeated calls, limited number of homogeneous terminals and 8 types
of losses is considered. One of the main problems of network redimensioning is estimation of the traffic offered in
the network because it reflects on finding of necessary number of equivalent switching lines on the basis of the
consideration of detailed users behavior and target Quality of Service (QoS).
The aim of this paper is to find a new solution of Network Redimensioning Task (NRDT) , taking into account
the inconvenience of necessary measurements, not considered in the previous research .
The results are applicable for redimensioning of every (virtual) circuit switching telecommunication system, both
for wireline and wireless systems (GSM, PSTN, ISDN and BISDN). For packet - switching networks proposed
approach may be used as a comparison basis and when they work in circuit switching mode (e.g. VoIP).
