2、 COPYRIGHT International Telecommunications Union/ITU TelecommunicationsLicensed by Information Handling ServicesFOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, ope
3、rating and tariff questions and issuing Recommen- dations 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 Groups which, in th
4、eir 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 (Helsinki, March 1-12, 1993). ITU-T Recommendation Q.822 was prepared by ITU-T Study Group 11 (1993-1996) and was approved und
5、er the WTSC Resolution No. 1 procedure on the 7th of April 1994. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

31、n for the Q3 Interface in a Telecommunication Management Network. Its focus is the parameter collection and storage, and the thresholding aspects of Performance Management. Included in this Description are specifications of the functions, management information, services, functional units, and proto
32、cols related to Performance Management. Significant re-use of OS1 system Management specifications is described in the X.700-Series Recommendations. This Recommendation may be applicable to other TMN-related interfaces. KEYWORDS Abstract syntax, attribute, function, functional unit, object class, pa

34、D STAGE 3 DESCRIPTION FOR THE Q3 INTERFACE - PERFORMANCE MANAGEMENT (Geneva, 1994) 1 Scope, purpose, and field of application 1.1 Scope This Recommendation provides a Stage 1, Stage 2 and Stage 3 Description (see Recommendation 4.68) for the parameter collection and thresholding aspects of Performan
35、ce Management. This Recommendation is part of a series of Recommendations that specify the Q3 interface (defined in Recommen- dation M.3010) requirements for communication: - - - - between an Operations System (OS) and a Network Element (NE); between an OS and a Mediation Device (MD); between an OS
36、and a Q Adaptor (QA); and between Operations Systems in a Telecommunication Management Network (TMN). 1.2 Purpose Current telecommunications networks are populated by a large and increasing number of OSs and NEs supplied by different vendors. Both the number and variety of networks and services have
37、 grown, creating a diversity of management needs. This growth has resulted in the proliferation of unique communication interfaces between OSs and NEs. The telecommunications industry stands to benefit from the standardization of these interfaces, designed to achieve interoperability between a broad
38、 range of OSs and NE/QAs using MDs where appropriate, and between OSS. The primary purpose of this document is to provide a set of application messages and associated support objects for the parameter collection and thresholding aspects of Performance Management. Because of the desirability of provi
39、ding common TMN solutions, these messages and support objects are expected to be applicable to other TMN or TMN-related interfaces. 1.3 Field of application This Recommendation defines an information model based on the specification of Managed Object classes. These Managed Object classes are support
40、ed through the interactive services specified in ITU-T Recommendation Q.8 12. 2 References The following Recommendations contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommen
41、dations are subject to revision, and parties to agreements based on this Recommendation are encouraged to investigate the possibility of applying the most recent edition of the Recommendations listed below. 2.1 Recommendations referred to in this Recommendation - - CCITT Recommendation M.3010.
