23、cation of PICS proforma corrigendaThe supplier of the PICS proforma shall identify any corrigenda (i.e. Technical Corrigenda or equivalent) to thepublished proforma that have been applied. Suppliers of the proforma should modify the proforma, or attach relevantadditional pages in order to apply the

24、corrigenda, and then record the application of the corrigenda in the table below.A.2 InstructionsA.2.1 Purpose and structure of the proformaThe purpose of this PICS proforma is to provide suppliers of implementations of CCITT Rec. X.229 | ISO/IEC 9072-2with a consistent means of stating which capabi

25、lities have been implemented.The proforma is in the form of a questionnaire and consists of a set of items. An item is provided for each capability forwhich an implementation choice is allowed. Items are also provided for major mandatory capabilities for which noimplementation choice is allowed. Eac

26、h item includes an item number, an item description, a status value specifying thesupport requirement, and room for a support answer to be provided by the supplier.This subclause provides general information and instructions for completion of the proforma.Subclause A.3 is for identification of the i

27、mplementation.Subclause A.4 contains the means of specifying, at a high level, the protocol and corrigenda that have beenimplemented.Subclause A.5 contains the global statement of conformance.Subclauses A.6 onwards contain tables in which the supplier specifies details of the implementation options

28、chosen.A.2.2 Symbols, terms and abbreviationsA.2.2.1 IntroductionNotations have been introduced in order to reduce the size of tables in the PICS proforma. These have allowed the use ofmulti-column layout where the columns are headed Status, and Support. The definition of each are given below.Additi

29、onally, the following definitions apply:A.2.2.1.1 (PICS) item: A row in a PICS proforma table.A.2.2.1.2 (PICS) question: The question to be answered in the intersection of a PICS item and either a support column(i.e. “Is this item supported in the context applying to this table and column”) or suppo

30、rted values column (i.e. “Whatvalues are supported for this item in the context applying to this table and column”) in a PICS proforma table.A.2.2.1.3 status (value): An allowed entry in the status column for an item in a PICS proforma table._1)Droits de reproduction du formulaire PICS: les utilisat

32、 Corr:3 Corr:4 Implementors Guide version:ISO/CEI 9072-3 : 1996 (F)4 Rec. UIT-T X.249 (1995 F)A.2.2.1.4 (support) answer: An allowed entry in the support or supported values columns for an item in a PICS, inanswer to a PICS question.A.2.2.2 Prerequisite notationIf a predicate applies to a whole PICS

33、 proforma table, a prerequisite line may be specified in front of the table to which itapplies. A prerequisite line takes the form:Prerequisite: The meaning of such a line is that if is True, then the table applies, else it is not-applicable.A.2.2.3 Item numberingEach line within the PICS proforma w

34、hich requires implementation detail to be entered is given an item number in thefirst column. The item number column provides a means of uniquely referencing each possible answer within the PICSproforma. Such referencing is necessary for specifying predicates, conditional expressions, test suite par

35、ameters, and testsuite selection expressions.The means of referencing individual answers is to specify the following sequence:a) If, and only if, the reference is being made from another Specification, then start with an unambiguousidentifier for the relevant ICS proforma specification, enclosed in

36、parentheses this identifier is stated inthe PICS proforma specification and is updated whenever the PICS proforma is updated it isrecommended that this identifier should be the relevant Specification number and year of publication, asis used in a Normative References clause, and this is the default

37、for such identifiers.b) The number of the relevant table or, if the tables are not numbered, of the smallest subclause enclosing therelevant table.c) A solidus character, “/”.d) The item number of mnemonic reference to the item, to identify the row in which the answer appears.e) If, and only if, mor

38、e than one question occurs in the row identified by the item number or mnemonicreference, then each possible answer is implicitly labelled a, b, c, etc. from left to right, and this letter isappended to the sequence, prefixed by a solidus character (“/”) if a mnemonic reference is used.If mnemonic r

39、eferences are specified and each uniquely identify an item in the PICS proforma, then entries b) and c) inthe above sequence may be omitted.A.2.2.4 Status columnThe Status column indicates the level of support required for conformance to CCITT Rec. X.229 | ISO/IEC 9072-2.The values are as follows:m

40、The item is mandatory. The capability is required to be implemented.o The item is optional. The capability may be implemented.o.n The item is a mutually exclusive or selectable option among a set (where n is the number whichidentifies the group of optional items). The requirement for each numbered g

41、roup is specified as partof the relevant tables.c The item is conditional. The requirement on the capability depends on the selections of otheroptional or conditional items. The status (mandatory, optional, prohibited, or non-applicable)depends on the evaluation of a predicate or a conditional expre

42、ssion which is specified as part of therelevant tables or as a The item is conditional (where n is the number which identifies the condition which is applicable).The definitions for conditional statements are given as part of the relevant tables.x The item is prohibited or excluded. There is a requ

43、irement not to use this capability in the givencontext.n/a The item is not applicable. The capability is not applicable in the given context.ISO/CEI 9072-3 : 1996 (F)Rec. UIT-T X.249 (1995 F) 5A.2.2.5 Support columnThe Support column shall be completed by the supplier or implementor to indicate the

44、level of implementation of eachcapability. The proforma has been designed such that the only entries required in the Support column are:Y Yes, the capability is implemented in conformance to CCITT Rec. X.229 | ISO/IEC 9072-2.N No, the capability is not implemented. No answer required it is unnecessa

45、ry to answer this question with a yes or a no because thequestion has a status value of non-applicable.A.2.2.6 Definition of supportAn operation class is said to be supported if the implementation is able to operate in the mode defined for that operationclass.A protocol element is said to be support

46、ed for origination if the implementation is able to generate it under somecircumstances (either automatically or because the end user explicitly requires a related service).A protocol element is said to be supported for reception if it is correctly interpreted, handled and, when required, madeavaila

47、ble to the end user.A.2.2.7 Predicate definitionsA predicate is an explicit reference to a PICS proforma YES/NO entry, using the format defined in A.2.2.4. If the entryis Y, it predicates the condition to be mandatory, otherwise optional.The following table lists the predicate definitions:p01 A.6.1/

48、6p02 A.6.1/7 and (A.6.1/1 or A.6.1/2 or A.6.1/4)p03 A.6.1/7 and (A.6.1/1 or A.6.1/2 or A.6.1/3)p04 A.6.1/7p05 A.6.1/6 and (A.6.1/1 or A.6.1/2 or A.6.1/4)p06 A.6.1/6 and (A.6.1/1 or A.6.1/2 or A.6.1/3)p07 A.6.1/8p08 A.6.1/9p09 A.6.1/3 or A.6.1/5p10 A.6.1/1 or A.6.1/2 or A.6.1/4p11 A.6.1/4 or A.6.1/5p12 A.6.1/1 or A.6.1/2 or A.6.1/3p13 A.6.1/8 or A.6.1/9A.2.2.8 Range of values columnsThe Permitted column indicates conditions applied to the support of a feature.
