10、000. ii ITU-T Q.2965.2 B (12/2000) 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,
11、operating and tariff questions and 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 tur
12、n, 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 technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE
13、 In this Recommendation, the expression “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 i
14、nvolve 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 the date of approval of this R
15、ecommendation, 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 databas

22、2 B Digital subscriber signalling system No. 2 Signalling of individual Quality of Service parameters: Protocol Implementation Conformance Statement (PICS) proforma 1 Scope This Recommendation specifies the Protocol Implementation Conformance Statement (PICS) proforma for the TBreference point or co
23、incident 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 basic call and connection control of the Digital Subscriber Signalling System No. 2 (DSS2) protocol for the Broadband Int
24、egrated Services Digital Network (B-ISDN), ITU-T Q.2965.2 1. This Recommendation is applicable to equipment, supporting B-ISDN calls/connections, to be attached at either side of a TBreference point or coincident SBand TBreference point when used as an access to the public B-ISDN. To evaluate confor
25、mance 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 an Implementation Conformance Statement (ICS). An ICS stating what capabilities and options have been implemented for a p
26、articular 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.2965.2 is required to complete a copy of the PICS proforma provided in Annex A. NOTE No PICS proforma is required to be completed for i
27、mplementation capabilities not covered by this Recommendation. For coverage of capabilities, refer to clause 6. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of
28、 publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below.

34、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 given specification, stating which capabilities have been impl
35、emented. 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 given protocol specification. 3.3 PICS proforma: A document, in
36、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 protocol entity at the user side of the user-network interface.

40、lementation. 6 Coverage This Recommendation covers requirements given in ITU-T Q.2965.2 1 as modified by ITU-T Q.2965.2/Amd.1 (1999). ANNEX A1PICS proforma for ITU-T Q.2965.2 A.1 Guidance for completing the PICS proforma A.1.1 Purpose and structure The purpose of this PICS proforma is to provide a m
41、echanism whereby a supplier of an implementation of the requirements defined in ITU-T Q.2965.2 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 requirements, i.e., filled
42、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 (see A.2.2 and A.5) and tables in A.6 to A.8 as appropriate shall be filled in (e.g. questions R.1, R.2, MCu 1, MCu 2, MCn 1, MCn 2 may be left not answered as
43、the same questions are contained in ITU-T Q.2931 B). In the second case, it is used to declare conformance to ITU-T Q.2965.2 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 co
44、mpleting the various 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 f
45、or the user role; A.8: Questions for the network role. _ 1Copyright release for PICS proforma Users of this Recommendation may freely reproduce the PICS proforma in this annex so that it can be used for its intended purpose and may further publish the completed PICS. 4 ITU-T Q.2965.2 B (12/2000) A.1
