It describes the structuring principles of the M.3200-Series and lists the currently agreed Recommendations. The concepts
7、 of “Telecommunications Managed Area“ and “Telecommunications Management“ are introduced. A summary description of each is provided, as well as a matrix defining their relationships. These Recommendations are intended as the basis for the corresponding modelling and protocol work on the TMN interfac
8、es. They also provide a basis from which an Administration might plan the evolution of its Telecommunications Management as defined in 3.2 of this Recommendation. The Recommendation is completed through a summary of a hypothetical example of the management context of a matrix crosspoint, i.e. Mainte

FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of
11、 the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes
12、 the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. I. In some areas of information technology which fali within ITU-Ts p
13、urview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. . NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU d
14、raws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU mem
15、bers or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU hadhad not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that thi
16、s may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1997 All rights reserved.

23、endation M.3200 (04/97) Recommendation M.3200 TMN MANAGEMENT SERVICES AND TELECOMMUNICATIONS MANAGED AREAS: OVERVIEW (I 992; revised in I997) 1 Scope This Recommendation is intended to provide an overview of Telecommunications Management Network (TMN) Management Services and Telecommunications Manag
24、ed Areas, It provides the framework for the specification of protocols, messages, management information, etc. for TMN interfaces. The TMN Management Services are described from the TMN users perspective and are independent of the protocols, messages and information models chosen. They will therefor
25、e assist in the smooth transition from a non-TMN to a TMN environment. It should be noted that flexibility will be required in the definition of TMN Management Services to enable additional requirements to be accommodated as they are identified. To avoid discrepancies and duplications, this Recommen
26、dation establishes the structuring principles (e.g. numbering, naming, etc.) for the M.3200-Series of Recommendations. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

35、ation M.8 17, Basic Functional Model for IMT-2000. Definitions This Recommendation defines the following terms. 3.1 telecommunications managed area: Telecommunications Managed Area is a set of telecommunications resources, logically and/or physically involved with the telecommunications services, th
36、at makes it possible to provide, partly or completely, these services to the customers and is chosen to be managed as a whole. Examples: Switched Data Network Switched Telephone Network 3.2 telecommunications management: Telecommunications Management, overall, is the result of integrating the manage
37、ment of the several Telecommunications Managed Areas of a company in order to maximize the quality to the telecommunications customers and the telecommunications resources productivity of a specific company, through performing the Management Services needed. The business objective of Telecommunicati
38、ons Management is to continually improve quality to the customer and operational productivity. Measures of continual improvement include: - - - The objectives of Management Services are to support, through re-engineered processes and automation, these business objectives. faster response to customer
39、s services demand; faster elimination of root causes of productivity degradation; improved accuracy of the bills and faster reception of them. 2 Recommendation M.3200 (04/97) STD-ITU-T RECMN M*3200-ENGL 1777 4862571 Ob37537 751 4 Abbreviations This Recommendation uses the following abbreviations: AA

44、nd Nemork Element management needs. The boundaries established through 5.1 up to 5.13 do not exclude the need of the integration established in the definition of Telecommunications Management, given in clause 3. The following are examples of the needed integration: a) All Telecommunications Services
45、 use resources of: Access and Terminal Equipment Network, Transport Network and Infrastructure. b) Packet Switched Data Services use Switched Telephone Network as part of their access. c) Freephone (e.g. 800 Service) use IN, Switched Telephone Network and ISDN resources to be accomplished. d) Cellul
46、ar Telephone Services are highly integrated with Switching Telephone Services. The management integration of the different Managed Areas and Management Services, within the OSS of a given TMN, is not subject of standardization. A Telecommunications Managed Area can range from a single piece of telec
47、ommunications equipment up to a very complex network. Depending on its network complexity, each company will organize its Telecommunications Management in a different way. This means that there is no standard to define which will be the Telecommunications Managed Areas of a specific company, when co
48、nsidered from a Management standpoint. The list below is a possible example.

NOTE - The above list is intended to apply to public and private networks. It is not intended to be exhaustive. Further revisions of this Recommendation may have additions. 5.1 Switched Telephone Network The Switched Telephone Network is the set of telephone exchanges or telephone switching nodes or simply switches that support the telephone service. These are switched circuit nodes. Nowadays, a number of different voice and data services flow th
