The CCIT (the International Telegraph and Telephone Consultativ
4、e Committee) is a permanent organ of the ITU. Some 166 member countries, 68 telecom operating entities, 163 scientific and industrial organizations and 39 international organizations participate in CCITT which is the body which sets world telecommunications standards (Recommendations). The approval
5、of Recommendations by the members of CCITT is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988). In addition, the Plenary Assembly of CCITT, which meets every four years, approves Recommendations submitted to it and establishes the study programme for the following perio
6、d. 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 CCITT Recommendation X.733 was approved on 10th of February 1992. The identical text is also published as ISO/IEC International St

17、ECHNOLOGY - OPEN SYSTEMS INTERCONNECTION - SYSTEMS MANAGEMENT: ALARM REPORTING FUNCTION 1 Scope This Recommendation I International Standard defines a Systems Management Function that may be used by an application process in a centralized or decentralized management environment to interact for the p
18、urpose of systems management, as defined by CCIT Rec. X.700 I ISO/IEC 7498-4. This Recommendation I International Standard defines a function which consists of generic definitions, services and functional units. This function is positioned in the application layer of the OS1 reference model (CCrrYr
19、Rec. X.200 I IS0 7498) and is defined according to the model provided by ISO/IEC 9545. The role of systems management functions is described by CCIIIT Rec. X.701 I ISO/IEC 10040. The alarm notifications defined by this function provides information that a manager may need to act upon pertaining to a
20、 systems operational condition and quality of service. This Recommendation I International Standard establishes user requirements for the darm reporting function; establishes a model that relates the service and generic definitions provided by this function to user requirements; defines the service
21、provided by the function; defines generic notification types and parameters documented in accordance with CCITT Rec. X.722 I specifies the protocol that is necessary in order to provide the service; specifies the abstract syntax necessary to identify and negotiate the functional unit in protocol; de
22、fines the relationship between this service and SMI notifications; specifies compliance requirements placed on other standards that make use of these generic definitions; defines relationships with other systems management functions; specifies conformance requirements. ISO/IEC 10165-4; This Recommen
23、dation I International Standard does not - - - - define the nature of any implementation intended to provide the Alarm Reporting function; specify the manner in which management is accomplished by the user of the Alarm Reporting function; define the nature of any interactions which result in the use
24、 of the Alarm Reporting function; specify the services necessary for the establishment, normal and abnormal release of a management association; preclude the definition of further notification types; - - define managed objects.
