8、e Amendment 1 to ITU-T Recommendation Q.822 (1994) was prepared by ITU-T Study Group 4 (2001-2004) and approved under the WTSA Resolution 1 procedure on 29 March 2003. ii ITU-T Rec. Q.822 (1994)/Amd.1 (03/2003) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialize
9、d agency in the field of telecommunications. The ITU 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 worl
10、dwide basis. The World Telecommunication Standardization 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 W
11、TSA Resolution 1. In some areas of information technology 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 admini
12、stration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicab
13、ility 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, ITU had not received notice of intellectual property, protected by patents, which may be required to implemen
14、t 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.

22、e Performance management. 3 Overview of the Generic Transport PM data information model This amendment provides the definition of new Generic Transport PM Data object classes. This new object classes are used for collection of performance data related to the GenericTransportTTP class (the terminatio
23、n of a generic transport connection). The Generic Transport TTP class is used to model physical ports or endpoints to underlying transport layers. Two new objects are defined in this amendment: GenericTransportPmCD and GenericTransportPmHD contain placeholders for current data and history data value
24、s for counters within the physical transport protocol monitoring grouping respectively. 2 ITU-T Rec. Q.822 (1994)/Amd.1 (03/2003) The GenericTransportPmCD object is subclassed from the CurrentData object defined in ITU-T Rec. Q.822. Inherited methods from CurrentData provide for retrieval of the Sus
25、pectFlag, retrieval of the ElapsedTime, activating or deactivating HistoryRetention, associating threshold data with a current data instance, and activating or deactivating the suppression of counters having all-zero counts. Additional inherited methods from Scanner provide for the setting of Admini
26、strativeState, retrieval of OperationalState, and setting of Granularity Period. Similarly, GenericTransportPmHD is subclassed from the HistoryData object defined in ITU-T Rec. Q.822. Inherited methods from HistoryData provide for retrieval of the SuspectFlag, retrieval of the ElapsedTime, activatin
27、g or deactivating HistoryRetention, associating threshold data with a current data instance, and activating or deactivating the suppression of counters having all-zero counts. For some digital signals, performance primitives in the incoming direction are reported to the far end via special messages
28、embedded within the signal format. Examples include: the Performance Report Message (PRM) in DS1 ESF, Far-End Block Error (FEBE) indicators in DS3 CC-bit applications, and Remote Error Indicators (REI) in SDH. With such a capability built into a transmission signal, reporting of transmission perform
29、ance parameters observed at the far end can be provided at the near-end. For this reason, the managed entity used to hold Generic Transport TTP performance management data contains placeholders for both near-end and far-end data. The GenericTransportPmCD object attributes are classified into six pac
30、kages: near-end path, near-end line, near-end section, far-end path, far-end line, and far-end section. Only the near-end path package attributes are mandatory. Other packages may be used whenever they are deemed relevant to the underlying transport technology. Clause 4 of this amendment defines a s
31、et of managed objects for the GenericTransportPmCD and GenericTransportPmHD classes. Figures 1 and 2 show the inheritance, containment, and association relationships of the managed objects defined in this amendment.
