This illustration summarizes elements of the Telecommunications Management Network (the TMN) that TELE-WORX consults on. This chart is not intended to be exhaustive; only the primary model concepts are indicated above. 

This illustration summarizes The Optical Internetworking Forum (the OIF) Control Plane. This illustration also summarizes elements of the Next Generation Network (the NGN) Management Model; NGN standardization efforts are currently ongoing. 


A great deal of confusion exists about the distinction between functions and devices. This chart attempts to illustrate both. For example, an Element Management System (an EMS) is a device that primarily performs element management-layer operations support functions (E-OSF).

Some other devices may also perform E-OSF’s. The Control Plane architecture is one such example that implements a set of classical E-OSF’s in the network element. This strategy generally reflects a move in the industry to push more functionality into the network element layer. This suggests a clear preference for fewer “boxes” (but accepting more complex “boxes”) in the network. 

Key Concepts:

    Hierarchy of Management Functional Layers - Business, Service, Network and Element

    Defined Interface Reference Points between Functions - Q, F, G, X

    Common Data Communication Network - DCN

    Defined processes for Strategy, Infrastructure, Product, Operations and Enterprise Management

“Foundation” Standards:

    ITU-T M.3010 Principles for a Telecommunications Management Network

    ITU-T M.3050 Enhanced Telecom Operations Map (eTOM)
