2、TU-T RECMN%Q.753. 3 95 4862593 0636462 bbT m FOREWORD The IT-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations on them wit
3、h 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 Recommendations on these topics. The approval of Re
4、commendations 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 4.751.1 was prepared by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 17th of October 1995.

24、 Part (MTP). It contains the Network Element Management Information Model for the MTP, that is the definition of network element managed objects. This Recommendation is part of a Series of Recommendations (Q.750) for management of SS No. 7 Network consisting of several signalling points. A signallin
25、g point is a node in the Signalling System No. 7 Network. This Recommendation only pertains to management of one single SS No. 7 network. 2 References The following Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommenda
26、tion. At the time of publication, the editions indicated were valid.

39、ment; c) fault management; d) Telecommunications Management Network (TMN). This Recommendation makes use of the following terms defined in Recommendation X.700: - object instance. This Recommendation makes use of the following terms defined in Recommendation X.701: a) managed object class; b) manage
40、ment information; c) notification. This Recommendation makes use of the following terms defined in Recommendation X.710: - attribute. 2 Recommendation Q.751.1 (10/95) This Recommendation makes use of the following terms defined in Recommendation X.720: a) inheritance; b) name binding; c) package; d)

45、10/95) 3 ITU-T RECMN*Q.75L- L 95 W 4862593 0636470 736 5 Conventions Recommendation A. 1500 is used for the elaboration and presentation of texts for Recommendations of the TmT-T. The Guidelines for the Definition of Managed Objects (GDMO), defined in Recommendation X.722, are used. In case of diffe
46、rences between the formal part (clause 7) and the informal parts of this Recommendation the formal part is to be regarded as leading. Throughout this Recommendation the wording “The managed object class x I refers to a particular managed object class while the wording “An x .I refers to an instance
47、of the managed object class “x“. Modelling of redundancy is avoided (e.g. relationships between managed objects are described in one MOC only). However, for some implementations, it may be useful or necessary to add some additional information to some managed object classes, depending on the users n
48、eeds. This can be done by subclassing. For all MTP protocol timers that are modelled in this Recommendation, it is implementation dependent what value they take when they are not used. 6 Informal description of managed object classes This clause gives an informal description - in alphabetical order
49、- of the managed object classes. Diagrams are presented for inheritance, containment and pointer relationships. For each object-class a brief description is given, including the attributes, notifications and actions. Each MOC is (informally) described using tables. In these tables, (I), (M) and (C) are used with the following meaning: - (I) This element is inherited from a superclass. - (M) This element is mandatory - (C) This element is optional, preconditions on presence may apply. Measurements for MTP are described in Recommendation
