Draft Final Report Chapter 7 Outline of Scope of Works attended on full time basis in NOC, resulting in shortening the communication time between the related departments and at the same time, the phenomena difficult to be identified by the individual supervising operation could be visualized. This operation can realize not only alive monitoring but also simplify to identify what is a bottle-neck problem of the system and result to an efficient Operation and Maintenance. (b) Incident response Fault recovery time can be reduced by reducing communication time between departments through integrated processing of monitoring information that is split among the departments and deployment of five technical department managers to the NOC building. Balanced maintenance organization that is free from numbers of local personnel can be established by using remote control technology and VPN (Virtual Private Network) etc. with local test and setting change. (c) Data analysis for communications management Management information from NMS shall be accumulated to Data Base. It shall be unified and managed to Graphical User Interface (GUI) to inform to NOC staffs. (d) Reporting Monitoring by using statics information, electronic reporting of performance information and e-mail at faulty occurred make for reduction of operation cost and the staffs loads. (3) Scope of upgrade The main functions of the integrated network monitoring system (NOC) to be furnished for the provision of user functions are as follows. (a) Network Monitoring Alive monitoring of network and system Monitoring of traffic Alarm log management/GUI display (b) Incident response Remote control VPN, Access control technology (c) Data analysis for communications management Correction and analysis of statistical information using NOC platform (Application/Data base) (d) Reporting Accumulation of fault records and auto generation. Information facility to staffs by e-mail etc. using NOC platform (Application/Data base) An outline of NOC functions is shown in Figure 7.1-18. 7-32
