For continuous from below Poisson process $$\xi(t)$$ with integer-valued jumps relations for the generating function of extrema are established. The distribution of the modified process $$\xi_{x}(t)$$ with instantaneous reflection on lower bound is expressed by these generating functions. For the process $$\xi_{x}(t)$$ under conditions of ergodicity the limiting distribution is found. This distribution is determined by the distribution of the absolute maximum of the given process $$\xi(t).$$ Relations for generating functions of the first exit time out of a finite interval for the process $$\xi(t)$$ in terms of resolvent of the process $$\xi(t)$$ are established. This resolvent is determined by the distribution of the extrema of the process $$\xi(t)$$.
