7、 to RU-i“ List of Recommendations. ITU-T RECOMMENDATION X.282 ELEMENTS OF MANAGEMENT INFORMATION RELATED TO THE OS1 DATA LINK LAYER Summary This revised Recommendation specifies the specification of management information related to the Data Link Layer, including the managed objects class definition
8、 of Data Link Layer managed objects, the relationship of the managed objects and attributes to both the operation of the layer and to other objects and attributes of the layer, and the allowable actions on the attributes of Data Link Layer managed objects. Source ITU-T Recommendation X.282 was revis
9、ed by ITU-T Study Group 7 (1997-2000) and was approved under the WTSC I Resolution No. 1 procedure on the 18th of June 1999. FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization S
10、ector (ITU-T) is a permanent organ of the ITU. The 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 Standardization Conference (WTSC), whic
11、h 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 of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information
12、 technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. i NOTE l I ! In this Recommendation the tem recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a publi
13、c correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the iTU (Geneva, 1992). I i i INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of
14、 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 outside of the Recommendation development process. As of the date of approval of this Recommendation
15、, the ITU 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 represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU

27、ment information within an Open System related to those operations of the OS1 Data Link Layer specified by the specifications in this Recommendation. Specifics on how Data Link layer management is accomplished is beyond the scope of this Recommendation. Data Link Layer management is defined by speci
28、fying: o the managed object class definition of Data Link Layer Managed Objects following guidelines put forth by the Structure of Management Information; the relationship of the Managed Objects and attributes to both the operation of the layer and to other objects and attributes of the layer; and t
29、he action type operations on the attributes of Data Link Layer Managed Objects that are available to OS1 Systems Management. Annexes E, F, G and H, which are integral parts of this Recommendation, provide ICs proformas associated with Data link layer management information. o 0 I 2 References The fo
