The -T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations o

3、n 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 IT-T Study Groups which, in their turn, produce Recommendations on these topics. The appro

4、val of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation 1.751 was prepared by ITU-T Study Group 15 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 19th of March 1

SUMMARY This Recommendation provides management requirements and an information model which pertain to the plane management of the ATM netwo

The information model describes the managed object classes and their properties that are used to describe the information exchanged across management interfaces defined in Recommendation M.301 O Telecommunications Management Network (TMN) architecture. This Recommendation specializes the

12、 generic object classes of Recommendations M.3100, 4.821 and 4.822 to provide the information model specific to the ATM network element.

Functional capabilities of the ATM NE are given in Recommendation 1.73 1 181, and in Recommendation 1.732 191. The physical layer management requirements ar

This Recommendation addresses the following areas of ATM network element management: Fault Management The Fault Management requirements covered in this Recommendation include the autonomous reporting of ATM NE componen

Performance Management The Performance Management requirements covered in this Recommendation include: 1) 2) 3) ATM Layer protocol monitoring; 4) PC/NPC violation monitoring: 5) Traffic monitoring; and 6) VPNC performance monit

19、or the management interface, it is necessary that the management requirements and the information model described herein match the functionality supported by the ATM NE described in Recommendation 1.732 19. Recommen- dation 1.732 19 does not require all functionality to be present in all ATM NEs. Th

20、erefore, not all the management requirements and all parts information model described in this Recommendation need to be present in a given ATM NE. The management interface requirements are independent of the NE implementation, either technological or geographical. i) Note that this Recommendation u

48、 Part of the MAF which is capable of responding to network management operations issued by a manager and may perform operations on managed objects, issuing events on behalf of managed objects. The managed objects can reside within the entity or in another open system. Managed objects from other open

49、 systems are controlled by a distant agent via a local manager. All ATMNEs will support at least one agent. Some ATMNEs will provide managers and agents (being managed). 3.2 management application function (MAF): An application process participating in system management.
