The Research And Realization For Centralized Supervisory Control System Of Transmission Network

Transmission technology has developed to SDH (Synchronous digital hierarchy) currently from PDH (Asynchronous digital hierarchy) early time. At present, the main market is tied in DWDM and flexible SDH . As Telecom split and come into market , China Telecom operation mechanism has changed at all at the same time. The competition has become more and more seriously in China telecom corporations. The focus in Telecom has diverted from expanding network only and enhancing quantity of users to providing exactly administration and the after service for users. AS the main one of China Telecom's Transmission Network, the circuits urgently need the ensuring from point to point and the new means of maintenance technology for the user, as the performance analysis. To realize the professional administration of Transmission Network.will need to Construct a wide Centralized Supervisory Control System.The article based on constructing Transmission Network Administration System what accords the idea of centralized maintenance and centralized supervisory. It is operating the need, analysis and realization of Centralized Supervisory Control System . By ITU-T advice .China has issued the national standard and department standard of SDH and DWDM. Chain Telecom has made many maintenance specifications of SDH and DWDM. The article has discussed database and the compare of concentricity and decentralization. The article has achieved the analysis, design and realization of database , hardware and software of Centralized Supervisory Control System of Transmission Network. The article has expatiated the methods of the functions and realization, as the module of Topo administration, the module of configuration administration and so on. The article has achieved the holistic construction Transmission Network System of and the construction of information and database.In the finality,the article has summarized many strongpoint and achievement in use and has raised many betterment against shortage in use. At the same time.The article has briefly discussed a few problems attended on System construction.
