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

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

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
