Research purposes： Currently more and more lines of urban mass transits in China will be increasingly networked. After doing research on the demand of telecommunication transmission system among networked lines of urban mass transit, the exploration was made on the way of making up network of telecommunication transmission system for urban mass transit, and one program of making up network of telecommunication transmission system, which could meet the need of transmission services of urban mass transit, was proposed for the purpose of providing basis and reference to the telecommunication development plan and development tactics of step construction of telecommunication for urban mass transit. Research methods： In accordance with the requirements of operational management and in combination with the technology development of making up network of telecommunication transmission system, the comparison and research were made for some programs from the areas of the principle and technology of making up network and composition of telecommunication transmission system for urban mass transit. Research results： The choices in technology and system composition of telecommunication transmission system for urban mass transit were presented under the different operational management mode. Research conclusions：The following suggestions were put forward： constructing network in different levels, choices of transmission system in technology, level composition of transmission system, plan and construction of control center of telecommunication transmission system, management of transmission network and synchronously construction of clock,etc.
