Studying On MAC Protocol For Concentrator & The Design Of Lower Layer Management Software

Both Telecommunication network and SDH network are made of multi-vendor or multi-type equipments now,which have their own network management systems developed according to different standard.It leads to not be able to intercommunicate between these systems,to manage telecommunication network integrally and to improve the efficiency and reliability of network operation. Therefore,it is necessary to develop a kind of telecommunication Integrated Network Management System, which can accomplish integrated management and optimization for different special network management systems, and bring the network management function well into play.In this thesis, on the basis of analyzing XunFang Comany's design document and design codes,according to the theorem of TMN and SMN,combining with HuaWei SDH 2500+ equipment and T2000 Element Management System,Designed the Integrated Network Management base frame with MML interface ,and achieved the base function of Fault Management Subsystem.This frame can be easy expanded by second time design,because of the Network Management System is a Computer network in essence,which intercommunicate to the telecommunication network with interface.
