15、zed 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 studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications
16、 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 Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is
17、 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 on a collaborative basis with IS0 and IEC. NOTE In this Recommendation the term recognized operating agency (ROA) includes any
18、individual, company, corporation or governmental organization that operates a public correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that
19、 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 members or others outside of the Recommen
20、dation development 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 informatio
21、n and are therefore strongly urged to consult the TSB patent database. O ITU 1999 All rights reserved.

28、 the network level view of transmission networks. It identifies TMN object classes that are common to managed telecommunications networks; or are of a generic type that can be used to manage a network at a technology-independent level; or are super-classes of technology-specific managed objects in a
29、 telecommunications network; or are management support objects that are required for the management of the telecommunications network. This Recommendation addresses generically the abstractions of those aspects of telecommunication resources required to manage the network with a network level view.
30、Recommendation G.805 on the architecture of the transport network is used as the basis in developing the transport aspects of this model. This Recommendation does not address abstractions relevant to technology-specific areas or implementation-specific details. 1.2 Purpose 1.2.1 Interoperability The
31、re will be a variety of TMN conformant management systems and managed systems concerning many technology-specific areas. One purpose of this Recommendation is to provide a vehicle for management interoperability between such systems. 1.2.2 Technology-independent management By introducing the concept
32、 of technology-independent management, it is possible to perform management of diverse networks using common communications interfaces. In this manner, an “abstract“ view over a set of networks can be achieved. 1.2.3 Facilitating information model development This Recommendation also provides a fram
33、ework from which technology-specific information models may be developed using the modelling principles defined in Recommendation X.720 (1 992), Information technology - Open Systems Interconnection - Structure of Management Information: Management Information Model. 1.3 Field of application This Re
34、commendation captures the generally applicable requirements of the technology-independent and technology-specific information models related to the network level view of transmission networks. Through specialization, this Recommendation is applicable to technology-specific TMN information models. Th
35、e mechanism for specialization is inheritance. Recommendation 6.855.1 (03/99) 1 Even though technology-specific models may be derived from this Recommendation, some of the generic managed object classes in this Recommendation are instantiable in order to provide interoperability between equipment su
36、pporting information models derived from this Recommendation and equipment that only supports the information model in this Recommendation. 1.4 Structure of this Recommendation The definition of management information in clauses 5 to 10, describing information model is documented using the notationa
37、l mechanisms defined in Recommendation X.722 (1 992), Information technology - Open Systems Interconnection - Structure of Management Information: Guidelines for the definition of managed objects. The relationships between the managed object classes for the different fragments of the model in clause
38、 5 are depicted using entity relationship diagrams. Clause 10 contains the syntax definitions of the information carried in the protocol. The notation used is Abstract Syntax Notation One (ASN. 1) defined in Recommendation X.680 (1 997), Information technology -Abstract Syntax Notation One (ASN. I):
39、 Specijkation of basic notation. When referencing the definitions for the templates in this Recommendation by other documents, the prefix “Recommendation G.855.1“ should be used to identiG the source for the definitions. The Management Conformance Summary is documented in Annex A using the conforman
40、ce summary tables specified in Recommendation X.724. The Managed Object Conformance Statements are documented in Annex B using the conformance tables specified in Recommendation X.724. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference i
