OMC – Operations Maintenance Centre
An Operations and Maintenance Centre is an element within a network management system responsible for the operations and maintenance of a specific element or group of elements. For example an OMC-Radio may be responsible for the management of a radio subsystem whereas an OMC-Switch may be responsible for the management of a switch or exchange. However, these will in turn be under the control of a NMC (Network Management Centre) which controls the entire network.
