The task of analysis of the non-Markov system of service is considered with refusals. The method offered in the article is based on Markov approximation of casual processes of receipt of requests and their service, which is carried out with the use of presentation of the real processes the streams of Erlang of the proper order. Correlations, settings distribution of probabilities of the states of the system, are got.
