4 Conformance requirement concerning PICS
If it claims to conform to the present document, the actual PICS pro forma to be filled in by a supplier shall be
technically equivalent to the text of the PICS pro forma given in annex A, and shall preserve the numbering, naming
and ordering of the pro forma items.
An ICS which conforms to the present document shall be a conforming PICS pro forma completed in accordance with
the instructions for completion given in clause A.2

Annex A (normative):
GEONETW PICS pro forma (Media independent)
A.1 Partial cancellation of copyright
Notwithstanding the provisions of the copyright clause related to the text of the present document, ETSI grants that
users of the present document may freely reproduce the GEONETW PICS pro forma in this annex so that it can be used
for its intended purposes and may further publish the completed GEONETW PICS.
A.2 Guidance for completing the ICS pro forma
A.2.1 Purposes and structure
The purpose of this PICS pro forma is to provide a mechanism whereby a supplier of an implementation of the
requirements defined in ETSI EN 302 636-4-1 [1] may provide information about the implementation in a standardized
manner.
The PICS pro forma is subdivided into clauses for the following categories of information:
- guidance for completing the ICS pro forma;
- identification of the implementation;
- identification of the ETSI EN 302 636-4-1 [1];
- global statement of conformance;
- PICS pro forma tables.
A.2.2 Abbreviations and conventions
The ICS pro forma contained in this annex is comprised of information in tabular form in accordance with the
guidelines presented in ISO/IEC 9646-7 [3].
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 item (e.g. parameters, timers, etc.). It implicitly
means "is supported by the implementation?".
ETSI

8 ETSI TS 102 871-1 V1.3.1 (2015-06)
Status column
The following notations, defined in ISO/IEC 9646-7 [3], are used for the status column:
m mandatory - the capability is required to be supported.
o optional - the capability may be supported or not.
n/a not applicable - in the given context, it is impossible to use the capability.
x prohibited (excluded) - there is a requirement not to use this capability in the given context.
o.i qualified 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.
c.i conditional - the requirement on the capability ("m", "o", "x" or "n/a") 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.
i irrelevant (out-of-scope) - capability outside the scope of the reference specification. No answer is
requested from the supplier.
NOTE 1: This use of "i" status is not to be confused with the suffix "i" to the "o" and "c" statuses above.
Reference column
The reference column makes reference to ETSI EN 302 636-4-1 [1], except where explicitly stated otherwise.
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 [3], are used for the support column:
Y or y supported by the implementation.
N or n not supported by the implementation.
N/A, n/a or - no answer required (allowed only if the status is n/a, directly or after evaluation of a conditional
status).
NOTE 2: As stated in ISO/IEC 9646-7 [3], support for a received PDU requires the ability to parse all valid
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.
Values 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: .
example: 5 . 20

- list of values: , , .,
example: 2, 4, 6, 8, 9
example: '1101'B, '1011'B, '1111'B
example: '0A'H, '34'H, '2F'H

- list of named values: (), (), ., ()
example: reject(1), accept(2)

- length: size ( . )
example: size (1 . 8)

Values supported column
The values supported 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 ICS pro forma a unique reference exists, used,
for example, in the conditional expressions. It is defined as the table identifier, followed by a solidus character "/",
followed by the item number in the table. If there is more than one support column in a table, the columns are
discriminated by letters (a, b, etc.), respectively.
EXAMPLE 1: A.5/4 is the reference to the answer of item 4 in table 5 of annex A.
EXAMPLE 2: A.6/3b is the reference to the second answer (i.e. in the second support column) of item 3 in
table 6 of annex A.
Prerequisite line
A prerequisite line takes the form: Prerequisite: .
A prerequisite line after a clause or table title indicates that the whole clause or the whole table is not required to be
completed if the predicate is FALSE.
A.2.3 Instructions for completing the ICS pro forma
The supplier of the implementation shall complete the ICS pro forma in each of the spaces provided. In particular, an
explicit answer shall be entered, in each of the support or supported column boxes provided.
If necessary, the supplier may provide additional comments in space at the bottom of the tables or separately.
More detailed instructions are given at the beginning of the different clauses of the ICS pro forma.
A.3 Identification of the implementation
A.3.1 Introduction
Identification of the Implementation Under Test (IUT) and the system in which it resides (the System Under Test
(SUT)) shall 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 shall both be filled in if they are different.
A person who can answer queries regarding information supplied in the ICS shall be named as the contact person.
