8、endations. Recommendation M.3000 (02/2000) 1 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 the ITU. The ITU-T is responsible for studyi
9、ng 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 the topics for study by the ITU-T Study Grou
10、ps which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared
11、 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 draws attention to the possibility that the pra
12、ctice 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 members or others outside of the Recommendation d
13、evelopment process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and ar
14、e therefore strongly urged to consult the TSB patent database. o ITU 2001 All rights reserved.

20、us expertise and TMN-related Recommendations are being developed in various Study Groups within ITU-T. This Recommendation has been developed to present a stable fiamework in the form of an umbrella Recommendation as a guide to all relevant development activities. Recommendation M.3000 (02/2000) V R
21、ecommendation M.3000 OVERVIEW OF TMN RECOMMENDATIONS 1 Scope The purpose of this Recommendation is to serve as an umbrella Recommendation for the development and use of TMN Recommendations within ITU-T. TMN Recommendations describe principles, architecture, definitions and specifications necessary t
22、o implement all types of TMNs. The contents of this Recommendation are the fields of application of TMN, areas to be studied (subject areas) in TMN Recommendations and areas of Recommendations that are referenced by TMN Recommendations (TMN-referenced Recommendations). Annexes A and B list the curre
23、nt TMN-related Recommendations. The users of this Recommendation are expected to be the experts who develop individual TMN-related Recommendations, those who utilize TMNs to manage telecommunication networks, and vendors and suppliers who implement TMNs. 2 Fields of application TMNs provide the mean
24、s used to transport, store and process information used to support the management of telecommunication networks and services. TMNs can be used for the management of telecommunication networks operated by Administrations, ROAS, customers, or other organizations and individuals. When these telecommuni
25、cation networks are connected with each other, their TMNs provide the means of exchanging information required to manage end-to-end telecommunication services. All types of telecommunication networks and network elements - such as analogue networks, digital networks, public networks, private network
26、s, 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 candidates for management by a TMN. There is in principle no limit to the fields of application. Sinc
27、e TMN Recommendations are still being developed, however, there is currently a practical limit to the variety of application fields that can be implemented. 3 Abbreviations This Recommendation uses the following abbreviations: ACSE Association Control Service Element AN Access Network AOM Applicatio

To derive

35、escribed in Recommendation M.3010, “Principles for a Telecommunications Management Network“. Three basic aspects are included in the TMN architecture. These are: - the TMN functional architecture; - - the TMN physical architecture. the TMN information architecture; and 4 Recommendation M.3000 (02/20

38、ure describes the appropriate distribution of functionality within the TMN, appropriate in the sense of allowing for the creation of function blocks fiom which a TMN of any complexity can be implemented. The definition of function blocks and reference points between them leads to the requirements fo
39、r the TMN-recommended interface specifications. The TMN information architecture is based on standardized open management paradigms that support the standardized modelling of the information to be communicated. TMN standardization activities will not develop a specific management paradigm but build
40、upon industry recognized solutions, focusing primarily on object-oriented techniques. Specific management paradigms may be used in TMN standards when judged to be adequate. The TMN physical architecture describes interfaces that can actually be implemented and examples of physical components that ma
41、ke up the TMN. Recommendation M.3000 (02/2000) 5 5.2.2 Interface specification methodology This methodology is described in Recommendation M.3020 and shows the precise steps in determining the individual items needed for the complete specification of TMN interfaces. Definitions and specifications ma
42、de at each step are important in maximizing the multiple use of the individual items of Recommendations. The TMN methodology shall therefore be followed when ITU-T Study Groups develop TMN Recommendations. 5.2.3 TMN management services Described fiom the users viewpoint of Operation, Administration,
43、 Maintenance and Provisioning (OAM b) Support information models are defined as abstractions of processes by which specific functional aspects of management are achieved. Examples of the latter are included in the Q.820-series Recommendations. Management is carried out across the TMN standards inter
44、faces using standard communication protocols and management-aspect protocols, the latter transporting management information defined in TMN management information models. Management information models and catalogue technology-specific models, e.g. for SDH. 5.2.6 Management information registration T
45、he assignment of object identifiers for TMN management information is structured in a fashion similar to the assignment of identifiers to OS1 systems management information and is described in Recommendation X.722. Properly defined management information is given a globally unique object identifier
46、and, with the approval of the defining Recommendation, is registered automatically. The development of a computerized database library of TMN management information is under study within the ITU-T. 5.2.7 Communication protocols Communication and management-aspect protocols in ITU-T Recommendations a
47、nd IS0 Standards are selected for the transfer of management information across TMN interfaces. Communication transport protocols include OSI, ISDN, Signalling System No.7, and TCP/IP. Management-specific protocols include OSIs CMIP, FTAM, X.500, ED1 and COBAS GIOP transported over IP (IIOP). Select
48、ed protocols are organized into protocol suites or profiles for specific TMN interfaces. The transfer syntax employed is described in the binary encoding rules (see Recommendation X.690). 6 Recommendation M.3000 (02/2000) 5.2.8 TMN utilizes the OS1 systems management services defined in the X.730-se
49、ries Recommendations and also provides additional management application functionality by means of TMN management messages in Q. 820-series Recommendations. This management functionality is made available for use across TMN interfaces by including it in a TMN-defined systems management application service element. Systems management services and management messages 5.2.9 Conformance TMN conformance requirements are a set of statements for protocols and information models to which TMN implementations must conform. These conformance statements are the basis upon which conformance tes
