8、 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.822.1 (2001)/Amd.1 (03/2003) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU

9、 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

10、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

11、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. INTELLEC

12、TUAL 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 applicability of claimed Intellectual Property Rights, wheth

13、er 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 implement this Recommendation. However, implementors are cau

23、rt PM Data object class. This new object class is used for collection of performance data related to the GenericTransportTTP (the termination of a generic transport connection). GenericTransportPmCDValueType and GenericTransportPmHDValueType contain placeholders for current and history data values f

24、or counters within the physical transport protocol monitoring grouping. 2 ITU-T Rec. Q.822.1 (2001)/Amd.1 (03/2003) The GenericTransportPmCD object class is subclassed from the CurrentData object class defined in ITU-T Recs Q.822 and Q.822.1. Inherited methods from CurrentData provide for retrieval

25、of the SuspectFlag, 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

26、 of AdministrativeState, retrieval of OperationalState, and setting of Granularity Period. Similarly, GenericTransportPmHD is subclassed from the HistoryData. For some digital signals, performance primitives in the incoming direction are reported to the far-end via special messages embedded within t

27、he 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 performance parameters o

28、bserved 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 arranged into six packages: near-end pat

29、h, 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 being modelled. Clause 4 defines a set of CORBA IDL interf

30、aces for the GenericTransportPmCD and GenericTransportPmHD objects. These interfaces are specified following the TMN CORBA framework and guidelines given in ITU-T Recs Q.816 and X.780 for fine-grained CORBA interface. In addition to the fine-grained interfaces in 4.4, a companion set of Faade interf

31、aces are defined in 4.5. These faade interfaces are defined according to the coarse-grained framework and guidelines given in ITU-T Recs Q.816.1 and X.780.1 for supporting coarse-grained CORBA interface. The name of these faade interfaces is the name of the corresponding fine-grained interface appen

32、ded with “_F“ (an underscore followed by a capital “F“). This amendment IDL is an integral part of ITU-T Rec. Q.822.1. This implies that all definitions (object classes, type, structure, .) defined in ITU-T Rec. Q.822.1 are in the same IDL module and can be referenced without the module identifier.

33、The IDL in this amendment has been compiled successfully without syntax error. The compiler used claims CORBA 2.3 compliance, which includes value type and M4 macro capabilities. Figures 1 and 2 show the inheritance, containment, and association relationships of the CORBA interfaces defined in this

34、amendment. Note that faade interfaces follow the same inheritance hierarchy relationship as the corresponding fine-grained interfaces.
