The CCIT (the International Telegraph
3、 and Telephone Consultative Committee) is a permanent organ of the IlU. Some 166 member countries, 68 telecom operating entities, 163 scientific and industrial organizations and 39 international organizations participate in CClT which is the body which sets world telecommunications standards (Recomm
4、endations). The approval of Recommendations by the members of CCIT is covered by the procedure laid down in CCT Resolution No. 2 (Melbourne, 1988). in addition, the Plenary Assembly of CCi“, which meets every four years, approves Recommendations submitted to it and establishes the study programme fo
5、r the following period“. In some areas of information technology which fall within CCITTs purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. The text of CCI“ Recommendation X.731 was approved on 17th of January 1992. The identicai text is also published as ISO/I

19、agement environment u interact for the purpose of systems management as defined by CX“ Rec. X.70 I ISO/JEC 74984. This Recommendation I International Standard defines the state management function and consists of service and generic defmitions. It is positioned in the , application layer of CClT Rec
20、. X.200 I ISO/IEC 7498 and is defined according to the model provided by ISOAEC 9545. The role of systems management functions are described by CC Rec. X.701 I ISO/IEC 1o040. This Recommendation I International Standard - establishes user requirements for the state management function; establishes m
21、odels that relate the service and generic definitions provided by this function to user requirements; defines the services provided by the function; defines generic attribute types, notification types and parameters documented in accordarice with CCITI Rec. X.722 I ISO/IEc 101654, specifies the prot
22、ocol that is necessary in order to provide the services; defines the relationship between the service and management operations and notifications; specifies compliance requirements placed on other standards that makes ase of these generic definitions; defines relationships with other systems managem
23、ent functions; specifies conformance requirements. This Recommendation I International Standard does not - - - - define the nature of any implementation intended to provide the state management function; specify the manner in which management is accomplished by the user of the state management funct
24、ion; define the nature of any interactions that result in the use of the state management function; specify the services necessary for the establishment, normal and abnormal release of a management association; preclude the definition of furtber notification types; - - define managed objects. 2 Norm

The state management provides for - - reading the state attributes; - changing the state attributes. the reporting of changes in the state attributes; 7 Model The m
48、anagement state of a managed object represents the instantaneous condition of availability and operability of the associated resource from the point of view of management. Different classes of managed object have a variety of state attributes that express and control aspects of the operation of thei
49、r associated resource that are peculiar to each class. However, the management state is expected to be common to a large number of resources and for this reason is standardized; it expresses key aspects of their usability at any given time. Its purpose is to control the general availability of a resource and to make visible information about that general availability. 7.1 Generic states Three primary factors affect the management state of a managed object with regard to its corresponding resources availabilit
