TMN Model: Telecommunications Management Network Model
Telecommunications Management Network (TMN) model was introduced by ITU-T Recommendation M.3000 in 1985 as a reference model for the Operation Support System (OSS) of telecommunications service providers. The TMN concept is an architectural framework for the interconnection of different types of OSS components and network elements. TMN also describes the standardized interfaces and protocols used for the exchange of information between OSS components and network elements, and the total functionality needed for network management.
