An examination is made of a queueing system M | G | 1 with waiting and with servicing intensity dependent on the state of the system in the following way: if just before the beginning of servicing of one order the number of orders in the system does not exceer n (where n > 1), the distribution function of the duration of servicing of the order is B//1(X) and if not it it B//2(X). Limit theorems are obtained for certain characteristics of the system in the case of various changes of its parameters.
