PURPOSE: A remote monitor integrated system of central offices is provided to integratedly operate optical terminal NMS(Network Management System) networks and monitor camera NMS networks of central offices, and to analyze performance in real time as monitoring operations, thereby stably operating a transmission network. CONSTITUTION: Each of central offices(1-7) sequentially connects NMS terminals(100) for controlling/monitoring each central office(1-7), hubs(200), routers(300), and CSUs(400). The NMS terminals(100) are used for controlling networks by a system manager, consisting of one program or a series of programs. The hubs(200) converge data into one place from one or more than one direction. The routers(300) connect separated networks using the same transmission protocol, and reciprocally connect network layers. The CSUs(400) synchronize cells. ATMs(600) control each of the central offices(1-7), and monitor the central offices(1-7).
