The impulse-phase tuning system with integrated filter and polygonal characteristic of phase detector is considered. One of the transitional proceses characteristics in the phase system --- the cycle-slipping number is analyzed. We are use the common criteria for the multidimensional discrete phase system purposely to get the estimates of initial data set for which the solutions have given estimate of cycle-slipping number. The estimates of initial data set which evaluated by use analytical methods are very close approximation to the "truth" boundaries of initial data set which evaluated by use numerical modeling of this impulse-phase system.
