Unicom 12 Optimization Of The Fixed Network Of The Chengdu Branch Of Engineering Analysis And Design

The most important the purpose of writing the paper is to give a solution for the 12th optimize about the PSTN network of the chinaunicom of the ChengDu Branch.he theory of the network regulation and the status in quo of PSTN is discussed in the paper. On the other hand, the design of the net and the orientation function of the switch are also analyzed. The problem on connect all kinds of the net between the different company is solved by the paper. The net could be work well than before. The most important problem of the project is fouced on the orientation of the function, rong bill. All of the ajust will be based on the demand. In the same time, another question should be also solved, especially connect with the others.The solution of the project is based on the several factor, such as the Getway, the regulation of the structure on network. In the same time, the step on PSTN in local is described, which is focused on the regulation, the direction of the electro circuit, and the expansion of the equipment. In order to turn the change into realities, the key steps of the whole ajust is also given. It is consist of serval aspects.The numbers of the bureau is so much. But the capability is not enough. It is difficult to mange for the equipment is repeated.The joint bureau is very complexity and so many arrangemen. The new severice is influenced.The capacity between the transformation and switch is broken so that there is no freely in the attemper on route and the quality of vice is not good.The old system on PSTN is not match the development of the modern ages.From the design, the best condition is provided. So that, it is easy to make PSTN of Chengdu to have enough ability on the safe, extend telephone proportion. It is obviously to given an advance reference case so as to establish an abundant foundation for the future.
