As an important part of the urban transportation system, urban rail transit undertakes a large number of passenger transportation tasks. In the process of rail transit operation, the communication system is one of the key factors to ensure the normal operation of trains, improve operational efficiency and enhance passenger experience. As an efficient communication tool, the dedicated telephone system provides urban rail transit staff with a wired telephone system for command means such as train operation, power supply, daily maintenance, disaster prevention and rescue, and ticket management. It is mainly composed of dispatching telephones, in-station direct telephones, inter-station driving telephones, and rescue telephones, and is widely used in the field of urban rail transit.
