It implicitlymeans "is supported by the implementation?".Status columnThe following notations, defined in ISO/IEC 9646-7 [6], are used for the status column:mmandatory - the capability is required to be supported.ooptional - the capability may be supported or not.n/anot applicable - in the given context, it is impossible to use the capability.xprohibited (excluded) - there is a requirement not to use this capability in the given context.o.iqualified 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.ciconditional - the requirement on the capability ("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.SIST EN 301 217-2:2001

ETSIETSI EN 301 217-2 V1.1.3 (1999-09)11Reference columnThe reference column makes reference to EN 301 217-1 [4] and EN 301 005-1 [3], except where explicitly statedotherwise.Support columnThe support column shall be filled in by the supplier of the implementation. The following common notations, defined inISO/IEC 9646-7 [6], are used for the support column:Y or ysupported by the implementationN or nnot supported by the implementationN/A, n/a or - 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 be ableto answer that a capability is supported for one profile and not supported for another. In that case, the supplier shallenter the unique reference to a conditional expression, preceded by "?" (e.g. ?3). This expression shall be given in thespace for comments provided at the bottom of the table. It uses predicates defined in the SCS, each of which refers to asingle profile and which takes the value TRUE if and only if that profile is to be used.EXAMPLE 1:?3:IF prof1 THEN Y ELSE NIt is also possible to provide a comment to an answer in the space provided at the bottom of the table.NOTE:As stated in ISO/IEC 9646-7 [6], support for a received PDU requires the ability to parse all validparameters of that PDU. Supporting a PDU while having no ability to parse a valid parameter isnon-conformant. Support for a parameter on a PDU means that the semantics of that parameter aresupported.References to itemsFor each possible item answer (answer in the support column) within the PICS proforma a unique reference exists, used,for example, in the conditional expressions. It is defined as the table identifier, followed by a solidus character "/",followed by the item number in the table. If there is more than one support column in a table, the columns arediscriminated by letters (a, b, etc.), respectively.EXAMPLE 2:A.5/4 is the reference to the answer of item 4 in table 5 of annex A.EXAMPLE 3:A.6/3b is the reference to the second answer (i.e. in the second support column) of item 3 in table 6of annex A.Values allowed columnThe values allowed column contains the type, the list, the range, or the length of values allowed. The following notationsare used:-range of values: . ;EXAMPLE 4:5 . 20.-list of values:, , ., ;EXAMPLE 5: 2, 4, 6, 8, 9.EXAMPLE 6:'1101'B, '1011'B, '1111'B.EXAMPLE 7:'0A'H, '34'H, '2F'H.-list of named values:(), (), ., (;EXAMPLE 8:reject(1), accept(2).SIST EN 301 217-2:2001

In this column, the values or theranges of values supported by the implementation shall be indicated.Prerequisite lineA prerequisite line takes the form: Prerequisite: .A prerequisite line after a clause or table title indicates that the whole clause or the whole table is not required to becompleted if the predicate is FALSE.A.1.3Instructions for completing the PICS proformaThe supplier of the implementation shall complete the PICS proforma in each of the spaces provided. In particular, anexplicit answer shall be entered, in each of the support or supported column boxes provided, using the notationdescribed in subclause A.1.2.However, the tables containing in "AN role" subclause shall only be completed for user implementations, and the tablescontaining in "SN role" subclause shall only be completed for network implementations.If necessary, the supplier may provide additional comments in space at the bottom of the tables, or separately on sheetsof paper.More detailed instructions are given at the beginning of the different subclauses of the PICS proforma.A.2Identification of the implementationIdentification of the Implementation Under Test (IUT) and the system in which it resides (the System Under Test(SUT)) should be filled in so as to provide as much detail as possible regarding version numbers and configurationoptions.The product supplier information and client information should both be filled in if they are different.A person who can answer queries regarding information supplied in the PICS should be named as the contact person.A.2.1Date of the statement.A.2.2Implementation Under Test (IUT) identificationIUT name:.IUT version:.SIST EN 301 217-2:2001
