At WTSA-08, SG2 was designated the Lead Study Group for Telecommunication Management. This role is a carryover and an expansion of the role of previous Study Group 4 as Lead Study Group for TMN held during the previous Study Period which was supported by the TMN Documentation Plan.
Concurrently, WTSA-08 also approved Q12/2 which is responsible for developing, maintaining, and regularly distributing an overview and/or work plan for the Telecommunication Management and OAM Project [this document - hereafter called the Telecommunication Management and OAM Project Plan (TM&OAMPP)].
SG2 subsequently assigned its Lead SG responsibility to Q12/2 to be supported by the TM&OAMPP which has replaced the TMN Documentation Plan and its successor, the Telecommunication Management Documentation Plan.
As noted in Q12/2, some aspects of telecommunications management and OAM are being developed in other Study Groups. Telecommunication management and OAM standardization activities include generic and technology-specific architectures, functional requirements, information models, and protocols for the specification of management and OAM interfaces between network elements, between network elements and management systems, and also between management systems. These interfaces may be divided into two categories:
- Telecommunication Management interfaces: between network elements and management systems; and also between management systems. [also known as FCAPS (fault, configuration, accounting, performance, and security management) interfaces]
- OAM interfaces: between network elements [also known as transmission interfaces] These activities also include the standardization of OAM functionality within network elements.
More specifically, these ITU-T activities include the management of telecommunication services, networks, and equipment, including support for next generation networks (NGN) and the application and evolution of the telecommunication management network (TMN) framework. Also included are other telecommunication management studies relating to designations, transport-related operations procedures, and test and measurement techniques and instrumentation.
All types of telecommunication networks and network elements - such as components of the NGN service and transport strata, analogue networks, digital networks, public networks, private networks, switching systems, transmission systems, telecommunication software, and logical resources of the network (such as a circuit, path, or telecommunication services supported by these resources) - are subject to management and OAM and such activities should be identified and tracked.
