7、roved under the WTSC Resolution No. 1 procedure on the 19th of April 1997. FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The I

8、TU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations 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 ITU-T Study Groups which, in their turn, 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. In some areas of information technology which fall within ITU-Ts purview, the ne

10、cessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention t

11、o the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others o

12、utside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had/had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not repre

27、tion that shall be available at management interfaces of the ISDN local exchanges. This information can be used by the TMN for performance management activities. ISDN-specific in-service measurements are defined for several of the 1.350 4 parameters in order to provide the TMN with an approximation

28、of the user perspective of these parameters, The TMN capabilities defined by this Recommendation will be applicable to all ISDN D-channels. Actual measurements will take place on a selectable subset of the available D-channels. This Recommendation has been developed to: - provide a network or servic

29、e provider with a means to get information about the performance of ISDN calls as far as they are related to the customer access and public part of ISDN. This Recommendation will: - provide the network performance measurement service descriptions at the network element management layer of the TMN as

30、 defined in Recommendation M.3010 6; - specifi the management information model to support this network performance measurement service. This will be done in terms of managed object classes, packages, attributes, notifications, actions and behaviour, using the OS1 management templates defined in X.7

31、22 as notation tool and using ASN.l for type definitions. Reuse of OS1 Management specifications in the X.700-series of Recommendations will be performed as much as possible. This Recommendation currently only defines measurements on separate calls. It gives no information on how to determine statis

32、tical results over several calls. This Recommendation only gives performance information on the selected D-channels. It should be used in conjunction with Recommendation M.364 1, which provides information on all D-channels. Besides, this Recommendation is only involved with performance aspects of t

33、he public part of the network. For performance or fault information on the user side, M.364 1 management information needs to be used. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recomme
