The technology of the telecommunication network is making progress continuously, and new networks and customer equipments are invented. In order to make these networks and equipments to link up the enormous fixed network of Chunghwa Telecom Co., Ltd. (CHT) smoothly, Network Operation Center(NOC) has to manage the trunk route of the fixed network in more detail. Then we can understand the events that happen between the switching network and the transmission network which belong to the fixed network. And we also desire to collect and realize the events that happen when those new networks and equipments link up the mobile network and the intelligent network of our company via NOC further. Finally we will be able to get the operation information of the entire telecommunication network precisely and immediately in the future. NOC Trunk Route Management System(TRMS) is developed for purpose of reacting to the configuration of the telecommunication network rapidly and analyzing the events so as to find out the trouble area in the network. Besides, TRMS can speed up the repair and recovery of the network. Also, it provides operation tools for the remote test and maintenance. Therefore, TRMS will be able to improve the quality of the entire telecommunication services and let CHT be always ahead of other telecommunication service providers.
