5 PICS proforma
5.1 Instructions for completing the PICS proforma
5.1.1 Other information
More detailed instructions are given at the beginning of the different clauses of the PICS proforma.
The supplier of the implementation shall complete the PICS proforma in each of the spaces provided. If necessary, the
supplier may provide additional comments separately in clause 5.4.
ETSI

---------------------- Page: 11 ----------------------
12 ETSI TS 186 009-1 V2.1.1 (2009-03)
5.1.2 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 reference specification [1] to [25] may provide information about the implementation in a
standardized manner.
The PICS proforma is subdivided into clauses for the following categories of information:
• instructions for completing the PICS proforma;
• identification of the implementation;
• identification of the reference protocol specification;
• PICS proforma tables (containing the global statement of conformance).
5.1.3 Conventions
The PICS proforma is composed of information in tabular form in accordance with the guidelines presented in
ISO/IEC 9646-7 [8].
Item column
It contains a number that identifies the item in the table.
Item description column
It describes each respective item (e.g. parameters, timers, etc.).
Reference column
It gives reference to the specification(s) [1] to [25], except where explicitly stated otherwise.
Status column
The following notations, defined in ISO/IEC 9646-7 [8], are used for the status column:
m mandatory - the capability is required to be supported.
n/a not applicable - in the given context, it is impossible to use the capability. No answer in the support
column is required.
o optional - the capability may be supported or not.
o.i qualified optional - for mutually exclusive or selectable options from a set. "i" is an integer which
identifies a unique group of related optional items and the logic of their selection which is defined
immediately following the table.
ci conditional - the requirement on the capability ("m", "o" or "n/a") depends on the support of other
optional or conditional items. "i" is an integer identifying a unique conditional status expression that
is defined immediately following the table. For nested conditional expressions, the syntax
"IF . THEN (IF . THEN . ELSE.) ELSE ." shall be used to avoid ambiguities. If an
ELSE clause is omitted, "ELSE n/a" shall be implied.
NOTE: Support of a capability means that the capability is implemented in conformance to the
specification(s) [1] to [25].
ETSI

---------------------- Page: 12 ----------------------
13 ETSI TS 186 009-1 V2.1.1 (2009-03)
Support column
The support column shall be filled in by the supplier of the implementation. The following common notations, defined
in ISO/IEC 9646-7 [8], are used for the support column:
• Y or y supported by the implementation.
• N or n not supported by the implementation.
• N/A or n/a or "no answer required" (allowed only if the status is N/A, directly or after evaluation
of a conditional status).
Values allowed column
This column contains the values or the ranges of values allowed.
Values supported column
The support column shall be filled in by the supplier of the implementation. In this column the values or the ranges of
values supported by the implementation shall be indicated.
References to items
For each possible item answer (answer in the support column) within the PICS proforma, a unique reference exists. It is
defined as the table identifier, followed by a slash character "/", followed by the item number in the table. If there is
more than one support column in a table, the columns shall be discriminated by letters (a, b, etc.) respectively.
EXAMPLE: 5/4 is the reference to the answer of item 4 in table 5.
5.2 Identification of the implementation
Identification 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 configuration
options.
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 ICS should be named as the contact person.
