The Transmission Network of Chunghwa Telecom (CHT) consists of several technologies from optical fiber, access network to SDH/DWDM core network. Currently these networks are managed by a variety of network management systems without communication to each other. However, managing transmission network in CHT has becoming more and more complex and difficult due to the keep- growing scope and the emerging new technologies. Concerning issues about organization reform, human resource reduction and operational expenditure savings, as well as to improve operations efficiency and effectiveness, an integrated transmission network management system called TINOS is currently under development. This article will first introduce the TINOS project, and then the adopted NGOSS technology. Following that, the system architecture and functional descriptions of TINOS will be described. Finally, some observations and issues of system consolidation and integration will be addressed.
