Foreword This European Standard (Telecomm

Part 5: Part 6: NOTE: The final structure of
16、 the parts containing the test specifications is currently under study. To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given Open Systems Interconnection (OSI) protocol. Such a statement is cal

The Protocol Specification of the present document, extends the Connection Modification procedures in EN 301 003-1 by supporting the modification of additional ATM traffic descriptors. This PICS provides additional statements of conformance

20、roadband-Integrated Services Digital Network (B-ISDN) by means of the Digital Subscriber Signalling System No. two (DSS 2) as specified in EN 301 276-1 2. It is the second EN in a family of ENS that concern the modification of ATM traffic parameters in B-ISDN connections. The supplier of a protocol
21、implementation which is claimed to conform to EN 301 276-1 2 is required to complete a copy of the PICS proforma provided in annex A of the present document in addition to the PICS proforma in EN 301 003-2 and is required to provide the information necessary to identify the supplier and the implemen
22、tation. Further ENS (or further parts of this EN) provide the method of testing and detailed application specific requirements to determine conformance to this EN. The provision of this service requires the support of the protocol for the basic point-to-point callhearer connections as defined in EN

A.1 G
35、uidance for completing the PICS proforma A.l .I Purposes and structure The purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation of the requirements defined in EN 301 276-1 2 may provide information about the implementation in a standardized manner. The PICS
36、 proforma is subdivided into subclauses for the following categories of information: - - identification of the implementation; - - global statement of conformance; - . guidance for completing the PICS proforma; identification of the ; A. 1.2 Abbreviations and conventions The PICS proforma contained
37、in this annex is comprised of information in tabular form in accordance with the guidelines presented in ISO/IEC 9646-7 7. Item column The item column contains a number which identifies the item in the table. Item description column The item description column describes in free text each respective
38、item (e.g. parameters, timers, etc.). It implicitly means “is supported by the implementation?“. ETSI STD-ETSI EN 301 27b-2-ENGL 1999 = 3400855 0387896 07T m 8 EN 301 276-2 V1.1.3 (1999-03) Status column The following notations, defined in ISO/IEC 9646-7 171, are used for the status column: m O da X
39、 mandatory - the capability is required to be supported. optional - the capability may be supported or not. not applicable - in the given context, it is impossible to use the capability. prohibited (excluded) - there is a requirement not to use this capability in the given context. ci 0.i qualified
40、optional - for mutually exclusive or selectable options from a set. “i“ is an integer which identifies an unique group of related optional items and the logic of their selection which is defined immediately following the table. conditional - the requirement on the capability (“m“, “o“, “x“ or “da“)
41、depends on the support of other optional or conditional items. “i“ is an integer identifying an unique conditional status expression which is defined immediately following the table. 1 irrelevant (out-of-scope) - capability outside the scope of the reference specification. No answer is requested fro
42、m the supplier. NOTE 1: This use of “i“ status is not to be confused with the suffix “i“ to the “o“ and “CI statuses above. c:o conditional optional - the capability may be supported or not if the hierarchically preceding capability is supported. c:m conditional mandatory - the capability is require
43、d to be supported if the hierarchically preceding capability is supported. Reference column The reference column makes reference to EN 300 443-1 i, except where explicitly stated otherwise. Support column The support column shall be filled in by the supplier of the implementation. The following comm
44、on notations, defined in ISO/IEC 9646-7 7, are used for the support column: Yory supported by the implementation. Norn N/A, da or - not supported by the implementation. no answer required (allowed only if the status is da, directly or after evaluation of a conditional status). If this PICS proforma
45、is completed in order to describe a multiple-profile support in a system, it is necessary to be able to answer that a capability is supported for one profile and not supported for another. In that case, the supplier shall enter the unique reference to a conditional expression, preceded by “?“ (e.g.
46、?3). This expression shall be given in the space for comments provided at the bottom of the table. It uses predicates defined in the SCS, each of which refers to a single profile and which takes the value TRUE if and only if that profile is to be used. EXAMPLE 1: NOTE 2: As stated in ISOLEC 9646-7 7
47、, support for a received PDU requires the ability to parse all valid ?3: IF prof1 THEN Y ELSE N. parameters of that PDU. Supporting a PDU while having no ability to parse a valid parameter is non- conformant. Support for a parameter on a PDU means that the semantics of that parameter are supported.
