The implementation of Network Operation Center (NOC) for Chunghwa Telecom has two different objectives. The first one is to assist the managing, administrating and operating people for monitoring and controlling the whole Chunghwa Telecom's telephone network. The other is to provide a mechanism for tracking telephone network out of service situation during disaster happened. In order to achieve the first objective, NOC integrates Switching Operation Support System(SOSS), Network Management System(NMS), Transmission Operation Support System(TOSS), Power Operation Support System(POSS) and ATM Network Management System. As to the second objective, NOC gets disaster reports from existing QOS system to supervise the malfunction of network element and its influence to customer. As long as any network element has serious out of service situation, the number of infected customer, the repair plan and the time of in service again are tracked step by step. In this article, we introduce the design philosophy of the NOC and its network infrastructure. Besides, the software functions and its design philosophy are also presented.
