The Optimization Of DanDong Local Transmission Network

Along with Telecommunication industry development, transmission network already transformed from the necessary network of exchange network and so on the specialized net into the foundation network of Telecommunication net. It provides the support for exchange,data,mobile and so on each service. The intensification of Telecommunication vocation competition makes the operation business more and more pay attention to the investment and income, and the optimization of existing resources. Thought network optimization, we can solve existent problem of our transmission network, enhance the security, the survivability, the expansibility and build the foundation for future development.The content of this article is involved with the modern communication. In this article, it makes the brief introduction of the modern communication, widespread used optical fiber transmission system, SDH transmission technology, and MSTP application based on SDH technical. It carries on the analysis of DanDong Unicom network from volume of traffic, protects, network structure, clock synchronization etc, discovers the network question, then proposes the transmission network optimized plan thought demand analysis of market development and volume of traffic. The plan solves the traffic questions, and makes the network safer.The construction of DanDong Unicom transmission network begins from the first project of DanDong Unicom. For some reasons as fund insufficiency, construction mentality and the time limit etc, transmission network is in the status of necessary network of other service network, and has not carried on the reasonable plan. Along with the rapid development of service, transmission unceasingly expands, questions slowly appear. In order to guarantee the network operation safely, steadily and highly effectively, fully use network resources, transmission network optimization is imperative under the situation.
