Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS).
The present document is part 1 of a multi-part deliverable covering the test specifications for access layer service access
points and related procedures as identified below:
Part 1: "Implementation Conformance Statement (ICS) proforma";
Part 2: "Test Suite Structure and Test Purposes (TSS&TP)";
Part 3: "Abstract Test Suite (ATS) and partial PIXIT proforma".
Introduction
Communications for Intelligent Transport Systems (ITS) is standardized at ISO TC204 WG16 under the name CALM
(Communications Access for Land Mobiles). The communications architecture of ITS is specified in ISO 21217 [2]. An
implementation view of CALM-compliant ITS stations is the concept of a "CALM Communications Kernel" (CCK)
presented in figure 1, which is based on the ITS station reference architecture specified in [2].

Figure 1: CCK specified in ISO 21217 [2]
The OSI protocol layers are grouped as shown in figure 1:
• The access layer contains OSI layers 1 and 2, providing the MI-interface towards the management entity, the
SI-interface towards the security entity and the IN-interface towards the networking & transport layer.
• The networking & transport layer contains OSI layers 3 and 4, providing the MN-interface towards the
management entity, the SN-interface towards the security entity, and the NF-interface towards the facilities
layer.
• The facilities layer contains OSI layers 5, 6 and 7, providing the MF-interface towards the management entity,
the SF-interface towards the security entity and the FA-interface towards the ITS-S applications.
Normally the MI-interface, the MN-interface, the MF-interface, the SI-interface, the SN-interface, the SF-interface, the
IN-interface and the NF-interface are described as non-observable and non-testable service access points (SAP).
CALM is designed for a distributed implementation in a station where router boxes and host boxes are interconnected
with a local area network (LAN). Each of these boxes (CCK) contains the functionality of the ITS-S router, as a
minimum. Management commands are exchanged between these CCKs by means of "Inter-CCK Communications" as
specified in ISO 24102 [3]. Such management commands directly may carry service primitives of SAPs to which they
are addressed. By this, elements of the service primitives become observable as PDUs and thus testable. Consequently
the present document provides also the foundations for testing elements of service primitives, but not the service
primitives themselves.
Further on the functionality of "Inter-CCK Communications" is used to enable access of the Tester to the "hidden"
SAPs in the SUT as specified in [4].
NOTE: At time of writing the present document, ISO TC204 WG16 was in the process to harmonize terminology
in the set of CALM standards. The following list shows the mapping of some new terms to previously
used terms:

1 Scope
The present document specifies "Implementation Conformance Statement" (ICS) proformas for the 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 ISO/IEC 9646-1 [5], ISO/IEC 9646-7 [6] and ETS 300 406 [7].
This proforma is intended for use by suppliers of equipment which is claimed to conform to the access layer service
access points and procedures as specified in ISO 21218 [1] in combination with a defined CALM-compliant CI.
Without a specific CALM-compliant CI, ISO 21218 cannot be tested.
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 CALM-compliant 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.

Annex A (normative):
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 ICS proforma in this annex so that it can be used for its
intended purposes and may further publish the completed ICS.
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 [6].
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

---------------------- Page: 10 ----------------------
11 ETSI TS 102 760-1 V1.1.1 (2009-11)
A.2.4 Status column
The following notations, defined in ISO/IEC 9646-7 [6] 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 [6], 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)

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.1.2.
If necessary, the supplier may provide additional comments in space at the bottom of the tables or separately.
