Q.834.4 (2003)/Amd.1 (01/2004) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The I
9、TU 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 Standardi
10、zation 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 tec
11、hnology 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. Compli
12、ance 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 oblig
13、atory 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 implementatio
14、n 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
15、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 cautioned that this may not represent the latest information and are therefore strongly urged to

31、e main Recommendation. 6 Enhancements to Build and Common interfaces This clause describes changes to Q834:Build and Q834:Common interface required to support the management of dynamic bandwidth allocation as well as the automatic ranging of ONTs or ONUs following one of the ranging mechanisms defin
32、ed in ITU-T Rec. G.983.1. First, operations used to construct or modify attributes for ONT or ONU network elements are modified to include input parameters required to properly characterize such network elements supporting dynamic bandwidth allocation and automatic ranging. Second, new operations ar
33、e added to provide the capability of construction of TCONTs, a partitioning of bandwidth intended for use at an ONT or ONU in conjunction with the dynamic bandwidth allocation protocol mechanisms. These operations are called buildTCONT, modifyTCONTParameters, and deleteTCONT. The new operations crea
34、te the need for a new exception called UnsupportedTCONTType, the enhancement of the definition of ParameterViolation exception, and the new use of an existing exception, InsufficientPONBW, by Q834:Build interface. Third, the data structures used to characterize ONTs and ONUs in Q834:Common are modif
35、ied to include these new attributes. Finally, new HistoryData record types are added to Q834:Common in order to allow for the performance monitoring of the dynamic bandwidth allocation function. They are called DBAFairnessPMHistoryDataType and TCONTTEPMHistoryDataType. All changes to Q834:Common and
36、 associated changes to Annexes A and B are combined with other enhancements and presented in clauses 12.2 , 10, and 11, respectively. 6.1 Modifications to clause 9.2.1.1, “buildNode“ a) Replace: “ in AdministrationDomainType administrationDomain) raises (UnrecognisedVersion, InvalidSerialNumSyntax,

The input sRInd specifies the new value for the
44、 status reporting characteristic of the ONT or ONU. The input administrationDomain identifies the domain to which the NE belongs.“ 4 ITU-T Rec. Q.834.4 (2003)/Amd.1 (01/2004) 6.4 buildTCONT This operation builds a TCONT in the Supplier Management System. The ONT or ONU associated with the TCONT must
45、 be provisioned prior to this operation. The operation signature for buildTCONT is shown below: ManagedEntityIdType buildTCONT ( in ManagedEntityIdType nEId, in TCONTType typeOFTCONT, in BWType maxBW, in BWType fixedBW, in BWType guaranteedBW, in UserLabelType userLabel) raises (UnknownNE, AccessDen
46、ied, InsufficientPONBW, UnsupportedTCONTType, DuplicateUserLabel); The input nEId identifies the ONT or ONU where the TCONT is to be terminated. The input parameter typeOFTCONT identifies which of the five TCONT types is to be constructed. The input parameters maxBW, fixedBW, and guaranteedBW identi
47、fy the bandwidth attributes that characterize the logical link end. The input userLabel provides a unique operator designation for the constructed TCONT, if such identification is desired. The return value of type ManagedEntityIdType provides unique identifier for the constructed TCONT. 6.5 modifyTC
48、ONTParameters This operation modifies the parameters associated with an existing TCONT in the Supplier Management System. The operation signature for modifyTCONTParameters is shown below: void modifyTCONTParameters ( in ManagedEntityIdType tCONTId, in BWType maxBW, in BWType fixedBW, in BWType guara
49、nteedBW, in UserLabelType userLabel) raises (UnknownManagedEntity, AccessDenied, InsufficientPONBW, DuplicateUserLabel); The input tCONTId identifies the TCONT whose characteristics are to be modified. The input parameters maxBW, fixedBW, and guaranteedBW identify the new bandwidth attributes that should characterize the logical link end. The input userLabel provides a unique operator designation for the constructed TCONT, if such identification is desired. The return value is of type void. 6.6 deleteTCONT This operation deletes a TCONT
