10、 FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized 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

11、 issuing Recommendations on them with a view to standardizing telecommunications on a worldwide 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 thes

12、e topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA 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 expre

13、ssion “Administration“ is used for conciseness to indicate both a telecommunication administration 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 Intell

14、ectual 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 the date of approval of this Recommendation, ITU had not receive

15、d 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. ITU 2001 All rights reserved. N

22、Recommendation specifies the Protocol Implementation Conformance Statement (PICS) proforma for the TBreference point or coincident SBand TBreference point (as defined in ITU-T I.413 4) of implementations conforming to the procedures for the handling of Quality of Service classes that may be used for

23、 basic call and connection control of the Digital Subscriber Signalling System No. 2 (DSS2) protocol for the Broadband Integrated Services Digital Network (B-ISDN), ITU-T Q.2965.1 1. This Recommendation is applicable to equipment supporting B-ISDN calls/connections, to be attached at either side of

24、a TBreference point or coincident SBand TBreference point when used as an access to the public B-ISDN. To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given protocol. Such a statement is called

25、an Implementation Conformance Statement (ICS). An ICS stating what capabilities and options have been implemented for a particular protocol is called a protocol ICS. This is commonly abbreviated to “PICS“. The supplier of a protocol implementation that is claimed to conform to ITU-T Q.2965.1 is requ

26、ired to complete a copy of the PICS proforma provided in Annex A. NOTE No PICS proforma is required to be completed for implementation capabilities not covered by this Recommendation. For coverage of capabilities, refer to clause 6. 2 References The following ITU-T Recommendations and other referenc

27、es contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid.

33、.1 1, ITU-T X.290 | ISO/IEC 9646-1 5, and ITU-T X.296 | ISO/IEC 9646-7 6 apply. In particular, the following terms defined in ITU-T X.290 | ISO/IEC 9646-1 5 apply: 3.1 implementation conformance statement (ICS): Statement made by the supplier of an implementation or system claimed to conform to a gi

34、ven specification, stating which capabilities have been implemented. The ICS can take several forms: protocol ICS, profile ICS, profile specific ICS, and information object ICS. 3.2 protocol implementation conformance statement (PICS): ICS for an implementation or system claimed to conform to a give

35、n protocol specification. 3.3 PICS proforma: A document, in the form of a questionnaire which, when completed for an implementation or system, becomes a PICS. The following definitions also apply: 3.4 network: DSS2 protocol entity at the network side of the user-network interface. 3.5 user: DSS2 pro

36、tocol entity at the user side of the user-network interface. 4 Abbreviations This Recommendation uses the following abbreviations: B-ISDN Broadband ISDN DSS2 Digital Subscriber Signalling System No. 2 IUT Implementation Under Test PDU Protocol Data Unit PICS Protocol Implementation Conformance State

39、tion. ITU-T Q.2965.1 B (12/2000) 36 Coverage This Recommendation covers requirements given in ITU-T Q.2965.1 1 as modified by ITU-T Q.2965.1/Amd.1 (1999). ANNEX A1PICS proforma for ITU-T Q.2965.1 A.1 Guidance for completing the PICS proforma A.1.1 Purpose and structure The purpose of this PICS profo

40、rma is to provide a mechanism whereby a supplier of an implementation of the requirements defined in ITU-T Q.2965.1 may provide information in a standardized manner. This PICS proforma may be used in two different ways. In the first case, it is used to declare conformance with DSS2 basic call requir

41、ements, i.e. filled in together with the PICS proforma provided in ITU-T Q.2931 B 3. In this case, at least the identification of the IUT, the global statement and tables related to the quality of service information element shall be filled in (see A.2.2, A.5, A.7.6, A.7.7, A.8.6 and A.8.7); all the

42、 other parts may be left unfilled. In the second case, it is used to declare conformance to ITU-T Q.2965.1 independently of ITU-T Q.2931 B and all information requested by this proforma shall be provided. The PICS proforma is subdivided into clauses as follows: A.1: Guidance for completing the vario

43、us parts of the PICS proforma; A.2: Identification of the implementation; A.3: Identification of the protocol to which this PICS proforma applies; A.4: Explanation of the PICS proforma tables; A.5: Global statement of conformance; A.6: Questions to determine roles; A.7: Questions for the user role;

44、A.8: Questions for the network role. A.1.2 Abbreviations and conventions The PICS proforma contained in this annex is comprised of information in tabular form in accordance with the guidelines presented in ITU-T X.296 | ISO/IEC 9646-7. Item column The Item column contains a unique reference (a mnemo

45、nic plus a number) for each item within the PICS proforma. Items are not always numbered sequentially. Item description column The Item description contains a brief summary of the static requirement for which a Support answer is required. _ 1Copyright release for PICS proforma Users of this Recommen

47、predicate upon which a conditional status is based. Status column The following notations, defined in ITU-T X.296 | ISO/IEC 9646-7, are used for the Status column: I Irrelevant or out-of-scope This capability is outside the scope of the Recommendation to which this PICS proforma applies and is not s

O Optional The capability may be supported or not. O.i qualified Optional For mutually exclusive or selectable optio

49、ns from a set. “i“ is an integer that identifies a unique group of related optional items and the logic of their selection, defined below the table. X eXcluded or prohibited There is a requirement not to use this capability in a given context.
