The work stability of modern high-performance digital networks that provide specified requirements for the speed and quality of information and speech stream transmission directly depends on the ability to maintain operating conditions at a constant level. The article proposes the structure of an automated air-exchange system of the telephone exchange switch room, which makes it possible to ensure stable operation of the telephone network with the specified characteristics, including the maximum performance. The explanations for the purpose and brief characteristics of the main nodes of the proposed structure are given. To solve the diagnostic problems and automatically switch on the reserve control channel, the authors recommend the air-exchange control system of the switch room on the basis of the multi-zone regulator. The features of the proposed system work are considered in its serviceable condition and in case of an emergency shutdown of the main channel. Recommendations for expanding the scope of the proposed structure are also given.
