The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ ofthe ITU. The ITU-T is responsible for studying technical, operating and tariff
10、questions and issuingRecommendations 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 their turn, produce Recom
11、mendationson these topics.The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down inWTSC Resolution No. 1.In some areas of information technology which fall within ITU-Ts purview, the necessary standards areprepared on a collaborative basis with ISO and IEC.

24、 between a Service Node (SN) and theTelecommunications Management Network (TMN) and between an Access Network (AN) and theTMN for the management associated with VB5.2 interfaces 4. The managed object classes neededin addition to those defined for VB5.1 interfaces 3 in Recommendation Q.832.1 13 are d
25、efined inthis Recommendation. The interface specified is that between TMN Network Elements orQ-Adapters which interface to TMN Operations Systems (OSs) without mediation and between OSsand Mediation Devices, as defined in Recommendation M.3010 5.Existing protocols are used where possible, and the fo
26、cus of the work is on defining the objectmodel. The definition of the functionality of TMN Operations Systems is outside the scope of thisRecommendation.Security management is also outside the scope of this Recommendation.The coordination of the Operation Systems of the Access Network and the Servic
27、e Node for bothVB5.1 and VB5.2 interfaces is within the scope of the planned ITU-T Recommendation Q.832.3(Access management for VB5).2 ReferencesThe following ITU-T Recommendations and other references contain provisions which, throughreference in this text, constitute provisions of this Recommendat

44、 Recommendation X.722/Amd.1(1995) on the SET-BY-CREATE property, the reader should be aware that Recommendation X.722/Amd.1(1995) has not been applied in the VB5.1 management specification.Objects and their characteristics and associated ASN.1 defined here are given names with capitalsused to indica
45、te the start of the next word and acronyms are treated as if they were words.Throughout this Recommendation, all new attributes are named according to the followingguidelines: The name of an attribute ends in the string “Ptr“ if and only if the attribute value is intendedto identify a single object.
46、 The name of an attribute ends in the string “PtrList“ if and only if the attribute value isintended to identify one or more objects. The name of an attribute is composed of the name of an object class followed by the string“Ptr“ if and only if the attribute value is intended to identify a specific
47、object class. If an attribute is intended to identify different object classes, a descriptive name is given tothat attribute and a description is provided in the attribute behaviour. The name of an attribute ends in the string “Id“ if and only if the attribute value is intendedto identify the name o
48、f an object, in which case this attribute should be the first one listed,should use ASN.1 NameType and should not be used to convey other information. The name of an attribute is composed of the name of an object class followed by the string“Id“ if and only if the attribute value is intended to iden
49、tify the name of the object classholding that attribute.4 General overviewThe following information model diagrams have been drawn for the purpose of clarifying therelations between the different object classes of the model.1) Entity-relationship models showing the relations of the different managed objects.2) Inheritance Hierarchy showing how managed objects are derived from each other (i.e. thedifferent paths of inherited characteristi
