The IT-
8、T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations on 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
9、study by the IT-T Study Groups which, in their tuni, produce Recommendations on these topics. The approval of Recommendations 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 X.160, was revised by IT-T Study
10、 Group 7 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 5th of October 1996. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. O ITU 1997 All right

17、14 11 Recommendation Xi60 (10196) STD-ITU-T RECMN X-Lb-ENGL L99b 48b251L Ob27b0 O90 m SUMMARY This Recommendation defines an architectural framework for a service to provide customers of network services with management capabilities. It also refers to Recommendations which directly relate to provisi
18、on of the service. The service is called the Customer Network Management (CNM). It allows customers and service providers to interact by electronic means, for the transfer of management information relating to public data network services being used by a customer. Customer Network Management address
19、es the requirement for efficient and effective interaction between customers and service providers. A consistent reference point is provided regardless of network services being managed. .

20、R PUBLIC DATA NETWORKS (revised 1996) 1 Scope This Recommendation is applicable to Customer Network Management (CNM) for Services provided by Public Data Networks. It may also apply to services provided by other networks. It defines the architectural framework for CNM making use of the concepts of S
21、ystems management, TivN and other related management standards. The relationship between the network service provider, network management, service management and the customer is presented in this Recommendation. The scope of management information provided to the customer extends from specific insta
22、nces of communication to a comprehensive view of all the services provided to the customers organisation. NOTE -Access control and security mechanisms are required and are for further study. 2 References The following Recommendations and other references contain provisions which, through reference i
23、n this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision: all users of this Recommendation are therefore encouraged to investigate the possibility of applying the most re
