21、me internationale)A.1 Identification 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 relevantadditiona
22、l pages in order to apply the 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 implementation of ITU-T Rec. X.225 | ISO/IEC 8327-1with a consistent
23、means of stating which capabilities have been implemented.The proforma is in 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 noimplementati
24、on choice is allowed. Each 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 clause provides general information and instructions for completion of the proforma.Subclause A.3 is for i
25、dentification of the implementation.Subclause A.4 contains the means of specifying, at high level, the protocol and corrigenda that have been implemented.Subclause A.5 contains the global statement of conformance.Subclauses A.6 onwards contain tables in which the supplier specifies details of the im
26、plementation options chosen.NOTE Throughout the PICS proforma, tables specifying Requestor and Accpetor roles are inserted as required forprecise definition of the status of SPDUs and SPDU parameters, but these tables shall not be used for static conformance review norfor test case selection.A.2.2 S
27、ymbols, 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 colums are headed Status, Support, Value, Mnemonic and Length. The definition ofeach are given belo

30、e 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 supported values column (i.e. “Whatvalues are supported for this item in the context applying to this table and column“) in a PI
31、CS proforma table.A.2.2.1.3 status (value): An allowed entry in the status column for an item in a PICS proforma table.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 Item numberingEach line within the
32、 PICS proforma which 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
33、, test suite parameters, 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 specificati
34、on, enclosed in 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 relevant Specification number and year of publication, as isused in a Normative References clause, and this is
35、the default 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 or mnemonic reference to the item, to identify the row in which the answer appears;e) if, and
36、only if, more 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.
37、If mnemonic references are specified and each uniquely identify an item in the PICS proforma, thenentries b) and c) in the above sequence may be omitted.A.2.2.3 Status columnThis column indicates the level of support required for conformance to ITU-T Rec.

38、aken from the Session Protocol Specification (see ITU-T Rec. X.225 | ISO/IEC 8327-1).A.2.2.3.1 Definitions applying to the tables in clauses A.4 to A.6The values are as follows: m Mandatory support is required. The implementation shall support the functionalities described inITU-T Rec. X.225 | ISO/I
39、EC 8327-1 for the specified item. o Optional support is permitted for conformance to ITU-T Rec. X.225 | ISO/IEC 8327-1. Accordingto some specific reason, the implementation is not obliged to support the specified item. Ifimplemented, it shall conform to the specifications and restrictions contained
40、in ITU-T Rec. X.225 |ISO/IEC 8327-1. Therefore the constraints described for the mandatory support above also apply.o.n Selectable options among a set of items (where n is the number which identifies the group ofoptionals which are linked together). The implementation shall support at least one of t
41、he givenitems. For the selected item(s), the constraints described for the mandatory support above The item is conditional (where n is the number which identifies the condition which is applicable).The definitions for the conditional statements used in Annex A are written under the table wherethey

UIT-T X.245 (1995 F) 5A.2.2.3.2 Definitions applying to the tables in clause A.7 (Supported SPDUs)The values are as follows:Sender item: m Mandatory support is required. The implementation shall be able: t
43、o build the SPDU (i.e. to build correctly the heading and all the mandatory parameters withinthe SPDU) in the situations required by the Protocol Machine; and to encode the SPDU into the TSDU, according to a valid encoding format. o Optional support is permitted for conformance to ITU-T Rec.

Ifimplemented, it shall conform to the specifications and restrictions contained in ITU-T Rec. X.225 |ISO/IEC 8327-1. Therefore the constraints described for the mandatory support above
45、 also apply.o.n Selectable options among a set of items (where n is the number which identifies the group ofoptionals which are linked together). The implementation shall support at least one of the givenitems. For the selected item(s), the constraints described for the mandatory support above The

Resolution of the condition (e.g. depending on protocolversion, protoc

The implementation shall be able: to syntactically identify the SPDU i.e. to decode the heading and all of the parameters which arepresent (Type and Length in TLV coding scheme);
48、 and to process it correctly. o Optional support is permitted for conformance to ITU-T Rec. X.225 | ISO/IEC 8327-1. Ifimplemented, it shall conform to the specifications and restrictions contained in ITU-T Rec. X.225 |ISO/IEC 8327-1.
