Introduction
To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and
options have been implemented for a telecommunication specification. Such a statement is called a "Protocol
Implementation Conformance Statement" (PICS).

Annex A (normative):
PICS proforma for the "ITS station-internal management
communications protocol"
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 PICS proforma in this annex so that it can be used for its
intended purposes and may further publish the completed PICS.
A.1 Guidance for completing the PICS proforma
A.1.1 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 ISO 24102-4 [1] may provide information about the implementation in a standardized manner.
The PICS proforma is subdivided into clauses for the following categories of information:
• guidance for completing the PICS proforma;
• identification of the implementation;
• identification of the protocol;
• global statement of conformance;
• PICS proforma tables.
A.1.2 Abbreviations and conventions
The PICS proforma contained in this annex is comprised of information in tabular form in accordance with the
guidelines presented in ISO/IEC 9646-7 [4].
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

9 ETSI TS 102 797-1 V1.2.1 (2014-06)
Status column
The following notations, defined in ISO/IEC 9646-7 [4], 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 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", "x" or "n/a") depends on the support of
other optional or conditional items. "i" is an integer identifying a unique conditional status
expression which is defined immediately following the table.
Reference column
The reference column makes reference to ISO 24102-4 [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 [4], 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: As stated in ISO/IEC 9646-7 [4], 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.

10 ETSI TS 102 797-1 V1.2.1 (2014-06)
References to items
For each possible item answer (answer in the support column) within the PICS proforma 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: B.5/4 is the reference to the answer of item 4 in table 5 of annex B.
EXAMPLE 2: B.6/3b is the reference to the second answer (i.e. in the second support column) of item 3 in table 6
of annex B.
Prerequisite line
A prerequisite line takes the form: Prerequisite: .
A prerequisite line indicates that the whole table is not required to be completed if the predicate is FALSE.
A.1.3 Instructions for completing the PICS proforma
The supplier of the implementation shall complete the PICS proforma in each of the spaces provided. In particular, an
explicit answer shall be entered, in each of the support or supported column boxes provided, using the notation
described in clause A.1.2.
However, the tables containing in "user role" clause shall only be completed for user implementations, and the tables
containing in "network role" clause shall only be completed for network implementations.
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 PICS proforma.
