In list item c) insert “optionally“ in front of “indicating“. Replace the existing figures 2 and 3 by the following figure 2 and

7、 renumber all remaining figures. Figure 2 - A profile RL item alongside the corresponding PICS proforma item ICs 35.1 00.01 Ref.

8、 control procedures, tests, conformity tests, implementation. O ISOIIEC 1997 Printed in Switzerland ISOAEC 9646-7:1995/Cor.l:1997(E) 0 ISOAEC Replace the last two paragraphs by: To use a profile RL, each table in it needs to be put alongside the corresponding table from the relevant ICs proforma. Th

9、is is illustrated in figure 2, which is also showing an example of a minimal profile RL item. This example shows that the profile has changed the status of Capability-A, which is item number 1 in the PICS proforma, from “o“ (i.e. optional) to “mai (i.e. mandatory). This means that conformance to the

10、 profile requires a support answer of “Yes“ for this item in the PICS. Notice that a profile RL is not an ICs proforma; it does not contain any questions, but rather restricts the acceptable answers to questions in the ICs proformas relevant to the profile. Page 22 Subclause 8.5.4 Replace the first

11、sentence of the second paragraph by: Support for the receipt of a particular PDU type shall be understood to imply support for parsing all valid instances of that PDU type, including decomposition of the PDU into all its parameters and the parsing of at least all semantically valid parameters. In so

12、me cases it may be necessary to parse all syntactically valid parameters in order to fully decompose the PDU into its parameters. Page 24 Subclause 8.7.3 In the third paragraph, replace the second sentence by: However it is more likely to be produced by copying selected tables from the relevant base

13、 specification ICs proformas and removing the column(s) to be completed by the supplier. Optionally the protocol status value column and allowed values columns may be deleted where required. A new set of columns giving the new profile requirements, both in terms of the status and allowed values are

14、then added. Page 44 Subclause C.5 Add to the second sentence of the first paragraph I, the shaded columns are optional and are included for clarification of the example.“ Modify the figures 34, 35 and 36 by shading as follows: 5.1 Classes Implemented number Class 1 Class O 14.1 2 Class 1 14.2 I I I

36、nal bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in field of mutual interest.

37、Other iiiteniatioiial organizations, governmental and non-govenimental, iii liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint techni

38、cal committee are circulated to iiational bodies for voting. Publication as an Iiiteriiational Standard requires approval by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 9646-7 was prepared by Joint Technical Cornnittee ISO/IEC JTC 1, Information technology, Sub

39、committee 21, Open S.ystezs Interconnection, data management and open distributed processing.

42、duction of OS1 conformance testing standards and standardized abstract test suites. ISO/IEC 9646-3 defines a standardized test notatioii. the Tree and Tabular Combined Notation (TCN) for the specification of a standardized Abstract Test Suite. ISO/IEC 9646-4 places requirements on test realization a

43、nd ISOIIEC 9646-5 places requirements on the conformance assessment process. ISO/IEC 9646-6 specifies requirements for the production of OS1 protocol Profile Test Specifications. This part of ISO/IEC 9646 specifies requirements for the development of Implementation Conformance Statements (ICs) for p

44、rotocols, profiles and information objects (such as managed objects). An ICs contains the necessary information required for confomaiice testing to the relevant requirements specified in OS1 specifications and their related profiles. The ICs proforma is in the form of a questionnaire or check-list t

45、hat is intended to cover all requirements, all optional and conditional functions, elements of procedure, parameters, PDUs, timers, etc. and other capabilities identified in the specification. The ICs proforma is to be completed by the supplier or the implementor. An overview of the System Conforman

46、ce Statements (SCSs), ICSs and their proformas is given in clause 6. Clause 7 describes the stnicture of SCS proformas. Clause 8 describes the requirements and layout of ICs proforma specifications and profile Requirements Lists (RLs). Clause 9 provides a complete specification for ICs proformas, as

47、 well as profile RLs, and describes requirements on the notation. Annex A provides guidance on the meaning of ICs status values and support answers. Aniiex B provides examples of profile RLs and profile specific ICSs. Annex C provides examples of PICS proforma tables and profile RL tables. Annex D p
