This Recommendation provides a generic network information model. It identifies TMN object classes that are common to managed telecommunication networks, or are of a generic type that can be used to manage a network at a technology-independent level, or are super-classes of technology specific managed objects in a telecommunication network, or management support objects that are required for the management of the telecommunication network. These objects are relevant to information exchanged across standardized interfaces defined in the [b-ITU-T M.3010] TMN architecture.
