Such a statement is called an Implementation ConformanceStatement (ICS). An ICS stating what capabilities and options have been implemented for a particular protocol is calleda protocol ICS. This is commonly abbreviated to "PICS".SIST EN 300 443-2 V1.2.3:2003

ETSIETSI EN 300 443-2 V1.2.3 (1999-09)7EN 300 443-1 [1] is derived from ITU-T Recommendation Q.2931 [5]. However, no PICS proforma exists for thisRecommendation. Therefore, ETSI has created a PICS proforma that is specific to the European environment. ThisPICS proforma reflects the requirements contained in ITU-T Recommendation Q.2931 [5] with the modificationsapplied by EN 300 443-1 [1]. This has been done to assist understanding of how the European requirements relate to therequirements contained within ITU-T Recommendation Q.2931 [5] (and in particular, to the options specified in thatrecommendation that are selected by the present document). In practical terms, this means that a number of capabilitiesspecified by ITU-T Recommendation Q.2931 [5] appear as items in this PICS proforma with a status more akin to thestatus that would be expected in a profile ICS (i.e. out-of-scope (I), prohibited (X)).SIST EN 300 443-2 V1.2.3:2003

No answer in thesupport column is required.OOptional - the capability may be supported or not.O.iqualified Optional - for mutually exclusive or selectable options from a set. "i" is an integer thatidentifies an unique group of related optional items and the logic of their selection, defined belowthe table.XeXcluded or prohibited - there is a requirement not to use this capability in a given context.Reference columnExcept where explicitly stated, the reference column refers to the appropriate text of ITU-T Recommendation Q.2931 asmodified by EN 300 443-1 describing the particular item.NOTE:A reference indicates only the location of the most essential information about an item. All additionalrequirements contained in EN 300 443-1 have also to be taken into account when making a statementabout the conformance of that particular item.Support columnThe following notation, defined in ISO/IEC 9646-7, is used for the support column:[ ] YesTick "Yes" if item is supported.[ ] NoTick "No" if item is not supported.[ ] N/ATick "N/A" if the item is "not applicable".Prerequisite lineA prerequisite line takes the form: Prerequisite: .A prerequisite line after a subclause heading or table title indicates that the whole subclause or the whole table is notrequired to be completed if the predicate is FALSE.A.1.3Instructions for completing the PICS proformaThe supplier of the implementation shall complete the PICS proforma. For each row in each PICS proforma table thesupplier shall enter an explicit answer (i.e. by ticking the appropriate "Yes", "No", or "N/A" in each of the supportcolumn boxes provided). Where a support column box is left blank, or where it is marked "N/A" without any tick box,no answer is required.If necessary, the supplier may enter additional comments at the end of each table, or separately.More detailed instructions may be found at the beginning of each subclause of the 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 to provide as much detail as possible regarding version numbers and configuration options.The product supplier 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.SIST EN 300 443-2 V1.2.3:2003

If the SUT implements more than one configuration, then a layer 3 PICS shall be createdfor each type of interface (and for each configuration of each interface) provided by the SUT.A.4.2Structure of the tablesThe supplier shall provide answers to the questions concerning the major roles of the IUT (see table A.1). The suppliershall then provide answers to the questions relating to the capabilities of the IUT in one of the major roles asappropriate. Apart from the initial questions to determine roles, the major roles of the IUT (the user role (R 1) and thenetwork role (R 2)) are treated completely separately in the PICS proforma. It is only necessary to complete thequestions for the supported role. Clause A.7 concerns the capabilities of the IUT whilst in the user role. Clause A.8concerns the capabilities of the IUT whilst in the network role.A.4.3Complexity of conditions in Protocol Data Unit (PDU)parameter tablesThe conditions governing when an individual information element has to be supported in a specific message are quitecomplex. To make the conditions for status easier to understand questions about these information elements have beensplit into several sub-items.A.4.4Support for received PDU parametersIn the PDU parameter tables (see subclauses A.7.5 and A.8.5), the PICS proforma asks questions about the informationelements (parameters) supported in messages (PDUs) received by the IUT.
