Abstract

The present work is devoted to the discussion of telecommunications development strategy in the world and the promotion of domestic developments. This article discusses the usage of teaching materials for defense network DISN for developing Russian communication network of civil defense of the new generation NG112 (NG - Next Generation). In this paper, we show the difficulties that exist in the transition from circuit switching (CS) to packet switching (KP). As the main obstacles, we discuss still existed ISDN channels, lack of SS7 refusal terms and lack of intelligent network architecture.
