Introduction
Communications for Intelligent Transport Systems (ITS) is standardized at ISO TC204 WG16 under the acronym
CALM (Communications Access for Land Mobiles). The communications architecture of ITS and cooperative ITS and
the concept of an ITS station (ITS-S) as a "Bounded Secured Managed Domain" (BSMD) are specified in
ISO 21217 [i.1]. The ITS station reference architecture is based on the OSI model as illustrated in figure 1.
An implementation of a BSMD is named an "ITS station unit" (ITS-SU), or more precisely and "Bounded Secured
Managed Entity" (BSME), which may consist of one or several physical units named "ITS station communication units"
(ITS-SCU). ITS-SCUs are interconnected via the ITS station-internal network specified in ISO 21217 [i.1].

Figure 1: Simplified ITS station reference architecture
The OSI protocol layers of an ITS-S are grouped as shown in figure 1:
• The ITS-S access layer contains OSI layers 1 and 2, using the MI-interface towards the ITS-S management
entity and the SI-interface towards the ITS-S security entity, and providing the IN-interface towards the ITS-S
networking & transport layer.
• The ITS-S networking & transport layer contains OSI layers 3 and 4, using the MN-interface towards the
ITS-S management entity, the SN-interface towards the ITS-S security entity, the IN-interface towards the
ITS-S access layer, and providing the NF-interface towards the ITS-S facilities layer.
• The ITS-S facilities layer contains OSI layers 5, 6 and 7, using the MF-interface towards the ITS-S
management entity, the SF-interface towards the ITS-S security entity and the NF-interface towards the ITS-S
networking & transport layer.
There are further interfaces not presented in the simplified view of figure 1, i.e. the interfaces towards "Applications",
which will be provided in an implementation by means of the API illustrated in figure 1.
The MI-interface, the MN-interface, the MF-interface, the SI-interface, the SN-interface, the SF-interface are specified
in ISO 24102-3 [2] as service access points (SAPs). The IN-interface is described as an SAP in ISO 21218 [1].
In a distributed implementation of an ITS-S, management commands are exchanged between the ITS-SCUs by means
of the "ITS station-internal management communications protocol" (IICP) specified in ISO 24102-4 [i.3]. Such
management commands may directly carry functions of service primitives of SAPs to which they are addressed. By
this, functions of the service primitives become observable as PDUs and thus testable. Consequently the present
document indirectly provides also the foundations for testing functions of service primitives, but not the service
primitives themselves.
The functionality of "ITS station-internal management communications" may be used to provide the upper tester access
in the SUT as specified in ISO 24102-3 [2], ETSI EG 202 798 [i.2], and ETSI TS 102 760-2 [i.4].
Details of the ITS-S access layer which are subject of the present document are illustrated in figure 2.

1 Scope
The present document specifies "Implementation Conformance Statement" (ICS) proformas for functionality of the
ITS-S access layer service access points MI-SAP and IN-SAP and related procedures as defined in ISO 21218 [1] in
accordance with the relevant guidance given in ETSI EG 202 798 [i.2].
This proforma is intended for use by suppliers of equipment which is claimed to conform to the functionality of the
ITS-S access layer service access points and procedures as specified in ISO 21218 [1] in combination with a defined
"Communication interface" (CI) described in ISO 21217 [i.1] . Without a CI supporting ISO 21218 [1], this proforma is
not applicable.
To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and
options have been implemented for a specific CI. Such a statement is called an Implementation Conformance Statement
(ICS). The present document provides proforma ICS templates, to be filled in by equipment suppliers.

Guidance for completing the ICS proforma
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 Guidance for completing the ICS proforma in this annex so that
it can be used for its intended purposes and may further publish the completed ICS proforma.
A.1 Purposes and structure
The purpose of this ICS proforma is to provide a mechanism whereby a supplier of an implementation of the
requirements defined in ISO 21218 [1] may provide information about the implementation in a standardized manner.
The ICS proforma is subdivided into clauses for the following categories of information:
• guidance for completing the ICS proforma;
• identification of the implementation;
• identification of the protocol;
• global statement of conformance;
• ICS proforma tables.
A.2 Abbreviations and conventions
A.2.1 General
The ICS proforma contained in this annex is comprised of information in tabular form in accordance with the guidelines
presented in ISO/IEC 9646-7 [3].
A.2.2 Item column
The item column contains a number which identifies the item in the table.
A.2.3 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

11 ETSI TS 102 760-1 V1.2.1 (2014-06)
A.2.4 Status column
The following notations, defined in ISO/IEC 9646-7 [3] and extended here, 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.
r as specified in the related referenced standard of the CI.
A.2.5 Reference column
The reference column makes reference to ISO 21218 [1], except where explicitly stated otherwise.
A.2.6 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).
A.2.7 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)

12 ETSI TS 102 760-1 V1.2.1 (2014-06)
A.2.8 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.
A.2.9 References to items
For each possible item answer (answer in the support column) within the ICS 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: 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.
A.2.10 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.3 Instructions for completing the ICS proforma
The supplier of the implementation shall complete the ICS proforma in each of the spaces provided. In particular, an
explicit answer shall be entered, in each of the "Support" column boxes provided, using the notation described in
clause A.2.
If necessary, the supplier may provide additional comments in space at the bottom of the tables or separately.

Annex B (normative):
Identification of the implementation
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 Identification of the implementation proforma in this annex so
that it can be used for its intended purposes and may further publish the completed ICS proforma.
B.1 General
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.
NOTE: The essential part of the IUT is the functionality specified in ISO 21218 [1]. The SUT, as a minimum, is a
communication interface (CI) as specified in ISO 21217 [i.1]. In what follows, the IUT thus referrers to
the functionality specified in ISO 21218 [1] applied in the context of a specific CI.
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.
