At WTSA-04, SG4 was designated the Lead Study Group for
Telecommunication Management. This role is a carryover and an expansion of
its role as Lead Study Group for TMN held during the previous Study Period
which was supported by the TMN Documentation Plan.
Concurrently, WTSA-04 also approved Q12/4 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)].
SG4 subsequently assigned its Lead SG responsibility to Q12/4 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 Q12/4, 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:
These activities also include the standardization of OAM
functionality within network elements.
- Telecommunication Management interfaces: between
network elements and management systems; and also between management
[also known as FCAPS (fault, configuration, accounting, performance,
and security management) interfaces]
- OAM interfaces: between network elements [also
known as transmission interfaces]
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
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.
