A.1.2 Abbreviations and conventions The ICs profor

16、ma contained in Annex B is comprised of information in tabular form in accordance with the guidelines presented in ISO/IEC 9646-7. 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 res

17、pective item (e.g. parameters, timers, etc.). It implicitly means 5s supported by the implementation?“. Status column The following notations, defined in ISOIEC 9646-7, are used for the status column: m O da X 0.i mandatory - the capability is required to be supported. optional - the capability may

18、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. qualified optional - for mutually exclusive or selectable options fi-om a set. “i“ is an integer which i

19、dentifies a 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“, “XI or “da“) depends on the support of other optional or conditional items. “i“ is an integer identifying a

20、n unique conditional status expression which is defined immediately following the table. ci Support column The support column shall be filled in by the network provider of the implementation. The following common notations, defined in ISOAEC 9646-7, are used for the support column: Y or y supported

21、by the implementation; N or n not supported by the implementation; N/A, da or - no answer required (allowed only if the status is da, directly or after evaluation of a conditional status). It is also possible to provide a comment to an answer in the space provided at the bottom of the table. Values

22、allowed column The values allowed column contains the type, the list, the range, or the length of values allowed. The following notations are used: range of values: list of values: example: 5 ,. 20 ex amp 1 e : , , . ., 2 74 96 ,8,9 example: example : OAH, 34H, 2FH example: reject(l), accept(2) exam

In particular, an explicit answer shall be entered, in each of the support or supported column boxes provided, using the notation described in subclause A. 1.2. If necessar

25、y, the network provider may provide additional comments in space at the bottom of the tables, or separately on sheets of paper. More detailed instructions may be given at the beginning of the different subclauses of the ICs profonna. Instructions for completing the ICs proforma A.2 Identification of
