5、one of a series of ECMA Standards defining services and signalling protocols applicable to BroadbandPrivate Integrated Services Networks (B-PISNs). The series uses B-ISDN concepts as developed by ITU-T and conforms tothe framework of International Standards for Open Systems Interconnection as define

6、d by ISO/IEC.This Standard has been produced by ECMA TC32-TG15 in collaboration with ETSI Technical Committee SignallingProtocols and Switching (SPS) under ETSI work item DEN/SPS-05132-2.The Standard is part 2 of a multi-part standard covering the Digital Subscriber Signalling System No. 2 (DSS2), B

7、roadbandInter-Exchange Signalling (B-QSIG), and Signalling System No. 7 (SS7) protocol specification for the Broadband IntegratedServices Digital Network (B-ISDN) and Broadband Private Integrated Services Network (B-PISN) Call Control, as describedbelow:Part 1: “Protocol specification“;Part 2: “Prot

9、ETSI as EN 302 092-3 and EN 302 092-4 respectively.To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and optionshave been implemented for a given Open Systems Interconnection (OSI) protocol. Such a statement is called a ProtocolImplemen

10、tation Conformance Statement (PICS).The Standard is based upon the practical experience of ECMA member companies and the results of their active andcontinuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardizationbodies. It represents a pragmatic

11、and widely based consensus.This ECMA Standard is technically aligned with EN 302 092-2 published by ETSI in November 1999.This Standard has been adopted by the ECMA General Assembly of December 1999.- i -Table of contents1Scope 12 Conformance 13 References 14 Definitions 14.1 Protocol Implementation

25、tation of therequirements defined in ECMA-294 may provide information about the implementation in a standardized manner.The PICS proforma is subdivided into subclauses for the following categories of information:- guidance for completing the PICS proforma;- identification of the implementation;- ide

26、ntification of the protocol;- global statement of conformance;- Roles;- Major capabilities;- Subsidiary capabilities;- Application protocol data units;- APDU parameters;- Timers.A.1.2 Abbreviations and conventionsThe PICS proforma contained in this annex is comprised of information in tabular form i

27、n accordance with theguidelines presented in ISO/IEC 9646-7.Item columnThe item column contains a number which identifies the item in the table.Item description columnThe item description column describes in free text each respective item (e.g. parameters, timers, etc.). It implicitlymeans “is suppo

28、rted by the implementation?“.Status column:The following notations, defined in ISO/IEC 9646-7, are used for the status column:m mandatory - the capability is required to be supported.o optional - the capability may be supported or not.n/a not applicable - in the given context, it is impossible to us

29、e the capability.o.i qualified optional - for mutually exclusive or selectable options from a set. “i“ is an integer whichidentifies an unique group of related optional items and the logic of their selection which is definedimmediately following the table.c.i conditional - the requirement on the cap

30、ability (“m“, “o“, “x“ or “n/a“) depends on the support ofother optional or conditional items. “i“ is an integer identifying an unique conditional statusexpression which is defined immediately following the table.- 4 -Reference column:The reference column makes reference to ECMA-294, except where ex

31、plicitly stated otherwise.Support column:The support column shall be filled in by the supplier of the implementation. The following common notations,defined in ISO/IEC 9646-7, are used for the support column:Y or y supported by the implementation.N or n not supported by the implementation.N/A, n/a o

32、r - no answer required (allowed only if the status is n/a, directly or after evaluation of a conditionalstatus).If this PICS proforma is completed in order to describe a multiple-profile support in a system, it is necessary to beable to answer that a capability is supported for one profile and not s

33、upported for another. In that case, the suppliershall enter the unique reference to a conditional expression, preceded by “?“ (e.g. ?3). This expression shall begiven in the space for comments provided at the bottom of the table. It uses predicates defined in the SCS, each ofwhich refers to a single

34、 profile and which takes the value TRUE if and only if that profile is to be used.EXAMPLE_: ?3: IF prof1 THEN Y ELSE NNOTEAs stated in ISO/IEC 9646-7, support for a received PDU requires the ability to parse all valid parameters of thatPDU. Supporting a PDU while having no ability to parse a valid p

35、arameter is non-conformant. Support for aparameter on a PDU means that the semantics of that parameter are supported.A.1.3 Instructions for completing the PICS proformaThe supplier of the implementation shall complete the PICS proforma in each of the spaces provided. In particular,an explicit answer

36、 shall be entered, in each of the support column boxes provided, using the notation described insubclause A.1.2.If necessary, the supplier may provide additional comments in space at the bottom of the tables or separately.More detailed instructions are given at the beginning of the different subclau
