6、endation Q.811 was approved on 13 February 2004 by ITU-T Study Group 4 (2001-2004) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. Q.811 (02/2004) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU

7、 Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-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 Standardiza

8、tion Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information techn

9、ology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Complian

10、ce with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligat

11、ory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation

12、of this Recommendation may involve the use of a claimed Intellectual Property Right. 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 th

13、e date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consul

Q.811 (02/2004) 1 ITU-T Recommendation Q.811 Lower layer protocol profiles for the Q and X interfaces 1 Scope This Recommendation is a part of a

19、 series of Recommendations dealing with the transfer of information for the management of telecommunications systems. This Recommendation defines the requirements of lower layer protocol profiles for the Q and X interfaces1, as defined in ITU-T Rec. M.3010 1 and in other M.3000-series Recommendation

20、s. The companion ITU-T Rec. Q.812 2 defines the requirements of the upper layer protocol profiles for the Q and X interfaces. The Q and X interfaces will support bidirectional data transfer for the management of telecommunications systems. The need for security functionality is recognized, but is no

21、t fully addressed in this Recommendation and is for further study. Users may need to use mechanisms outside this Recommendation in order to address their specific security needs. Security mechanisms chosen may depend on the network configuration being used. If new operational requirements are develo

22、ped that imply distinctions to be made here between the Q and X interfaces, future versions of this Recommendation, or possibly new Recommendations, will reflect these differences. This Recommendation defines: the layer service profiles for the defined supported networks; the layer protocol profiles

23、 for the defined supported networks; the requirements at the layer 3/layer 4 service boundary for any network used to support the Q and X interfaces of the TMN. This Recommendation conforms to the “T“ profiles in framework for International Standardized Profiles (ISP) as specified in ISO/IEC TR 1000

24、0-1 63 and ISO/IEC TR 10000-2 64. Profiles in this Recommendation align with equivalent ISPs (as specified in conformance clause) if available. It is the intention to align those profiles for which there are no equivalent ISPs at present to ISPs as they are standardized by ISO SGFS. 2 References The

25、 following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
