9、tion X.161 was revised by ITU-T Study Group 7 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 9th of August 1997. Recommendation X.161 (08/97) i - STD-ITU-T RECMN X-LbL-ENGL 1997 = 48b2591 Ob45552 409 - FOREWORD IT (International Telecommunication Union) is the United N
10、ations Specialized Agency in the field of telecommuni- cations. The ITLJ Telecommunication standardization Sector (IT-T) is a permanent organ of the ITU. The IT-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing te
11、lecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members
12、 of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. . in some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is us
13、ed for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. T
14、he ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received notice of inte

25、118 = Recommendation X161 DEFINITION OF CUSTOMER NETWORK MANAGEMENT SERVICES FOR PUBLIC DATA NETWORKS (revised in 1997) 1 Scope This Recommendation defines the management services and supporting functions for CNM. Where possible, reference is made to other Recommendations which define management ser
26、vices and functions. This Recommendation is intended to complement TMN specifications and provide a specification for the non-TMN environment. The relationship of this Recommendation to other Recommendations for CNM is presented in Recommendation X. 160. Definitions of management information for the
27、 currently defined CNM interfaces are in Recommendations X. 162 and X. 163. This Recommendation is applicable to provision of the CNM Service in the Public Data Network (PDN) environment. In future, this may extend to other network technologies. The specification contained in this Recommendation is
28、written such that it may be developed to be generic to all network technologies where the requirement for CNM is identified. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. A
29、t 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 recent edition of the Recommendations and other references lis

44、commendation. M Mandatory O Optional - Not defined N/A Not Applicable FS Furtherstudy C Conditional 6 Overview of Customer Network Management services A CNM service is a capability that is provided to a customer across a CNM interface. A CNM service is provided for example by using CMIS, OS1 Systems
45、 Management Functions and appropriate management information. Alternatively, a CNM service can be provided by exchanging ED1 forms over MHS. The services currently defined in this Recommendation (and summariced in Annex A) are those services which are considered to be of most importance to customers
46、, and are therefore priorities for provision. Further services are identi- fied but are considered to be of lower priority. Other CNM services may be added in future when frther OS1 System Management Functions have been completed and additional business requirements have been identified. The CNM ser
47、vices defined in this Recommendation are, for convenience, classified into six groups: - Fault Management; - Accounting Management; - Configuration Management; - Performance Management; - Security Management; - CNM supporting services. This Recommendation should be read in conjunction with Recommend
48、ation X. 160, which defines the CNM Architecture, and Recommendations X.162 and X.163, which define management information for CNMc and CNMe interfaces, respectively. 7 CNM services definitions The following clauses describe the CNM services that may be provided across the CNM interfaces. When the s
49、ervice is provided across the CNM interface, the description is made in accordance with the TMN interface specification methodology defined in Recommendation M.3020. In the case of the CNMc interface, the term “CNM service“ is fully equivalent to the term “TMN Management function set“ and the associated management information is defined in Recommendation X.162. When the service is provided across the CNMe interface, the description is made using ED1 forms. These forms are defined in Recommendation X. 163. Elements of procedure to be used for provision of CNM services are
