OMC Overview

Introduction to OMC

The Core Network OMC (Operation and Maintenance Center) is a central facility used by operators to manage and maintain core network equipment. It typically includes modules for network monitoring, fault management, performance management, configuration management, security management, and other functions to ensure the smooth operation and efficient maintenance of core network equipment. By monitoring and managing core network equipment, the OMC can quickly identify and resolve network faults in real-time, improve network performance, ensure network security, and enhance operational efficiency. The OMC plays a crucial role in the network operations and maintenance of operators, serving as a key element in ensuring stable network operation.
