Foreword
This ETSI Guide (EG) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document is part 1 of a multi-part EG covering Integrated Services Digital Network (ISDN); Network
Integration Testing (NIT); ISDN/PSTN end-to-end testing, as identified below:
Part 1: "Test Suite Structure and Test Purposes (TSS&TP) specification";
Part 2: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma for the network".
Introduction
The present document contains the Abstract Test Suite (ATS), Implementation Conformance Statement (ICS) and
Implementation eXtra Information for Testing (IXIT) list developed in the EURESCOM project P613 "Methodology
and tools for ISDN Network Integration and Traffic Route Testing" for testing the international European ISDN,
covering Network Integration Testing (NIT) between ISDN-ISDN, ISDN-PSTN and PSTN-ISDN networks. The
objective is to verify the level of international end-to-end support of ISDN services. Both bearer services (and
associated teleservices) and supplementary services are checked for interworking capability and compatibility, in the
international European ISDN.
The European ISDN is made up by connecting the different national networks and End-to-end NIT covers all the testing
activities necessary to assess the correct behaviour of the interconnected network from the point of view of access
interfaces, network side.

5 Abstract Test Method
5.1 Description of ATM used
The Abstract Test Method (ATM) chosen for this testing specification is the distributed multiparty test method. The
ATM is defined at an appropriate level of abstraction so that the test cases may be specified appropriately, without
adding restrictions to the implementation under test. The testing architectures are described in the following subclause.
The ATS is written in concurrent TTCN.
5.2 Test method
The requirement for testing the network SUT is to focus on the behaviour of the network SUT at two user-network
interfaces where a T reference point or coincident S and T reference point applies.
It is possible to specify an ATS based on a Single party (remote) test method for such a SUT. However, it is considered
that an ATS based on such an approach is of limited use as the only way to specify SUT generated PDUs is to use the
"implicit send" statement. Many users of such an ATS would replace the "implicit send" statements with descriptions of
the behaviour at other interfaces.
An ATS based on a multi-party test method is considered to be more useful in that it is closer to how a real test suite
would be constructed. Such a test method specifies behaviour at multiple network interfaces. The test system is made up
of one Main Test Component (MTC) and one or more Parallel Test Components (PTC), see figure 1.
To observe the end-to-end mapping between DSS 1 layer 3 parameters and information elements on two remote ISDN
accesses, for each side a Point of Control and Observation (PCO) is needed. The PCOs used by the lower tester to
control the ISDN signalling are abbreviated with LA and LB. The ISDN PDUs to be sent and observed on the LA and
the LB PCO side allow for PDU constraints to be specified and coded down to the bit level.

Inamaster/slavearrangement,the MTCisconsideredtobethe master while thePTCsare theslaves. TheMTCMhas
only one function in this configuration. It has the pure MTC function of controlling the two or more PTCs. Thus it is
responsible for starting the PTCs and afterwards co-ordinates activities by exchanging Co-ordination Messages (CM)
with the PTCs.
The "slave" testers are an explicit description of how to deal with the user-network interfaces during the testing process,
i.e. "how to make the SUT send the required message".
6 Conformance to this ICS and IXIT proformas
specification
If it claims to conform to the present document, the actual ICS proforma to be filled in by a supplier shall be technically
equivalent to the text of the ICS proforma given in annex A, and shall preserve the numbering/naming and ordering of
the proforma items.
An ICS which conforms to the present document shall be a conforming ICS proforma completed in accordance with the
guidance for completion given in clause A.1.
A test realizer, producing a executable test suite for this ATS specification is required, as specified in
ISO/IEC 9646-7 [17], to produce an augmented partial IXIT proforma conformant with the text of the partial IXIT
proforma given in annex B.
An augmented partial IXIT proforma which conforms to this partial IXIT proforma specification shall, as a minimum,
have contents which are technically equivalent to annex B. The augmented partial IXIT proforma may contain additional
questions that need to be answered in order to prepare the Means Of Testing (MOT) for a particular IUT. The test
laboratory may further augment the augmented partial IXIT proforma to produce a IXIT proforma conformant with this
partial IXIT proforma specification.
An IXIT proforma which conforms to this partial IXIT proforma specification shall, as a minimum, have contents which
are technically equivalent to annex B. The IXIT proforma may contain additional questions that need to be answered in
order to prepare the test laboratory for a particular IUT.
7 ATS Conformance
The test realizer, producing a Means Of Testing (MOT) and Executable Test Suite (ExTS) for this Abstract Test Suite
(ATS) specification, shall comply with the requirements of ISO/IEC 9646-4 [18]. In particular, these concern the
realization of an Executable Test Suite (ExTS) based on each ATS. The test realizer shall provide a statement of
conformance of the MOT to this ATS specification.
An ExTS which conforms to this ATS specification shall contain test groups and test cases which are technically
equivalent to those contained in the ATS in annex C. All sequences of test events comprising an abstract test case shall
be capable of being realized in the executable test case. Any further checking which the test system might be capable of
performing is outside the scope of this ATS specification and shall not contribute to the verdict assignment for each test
case.
A test laboratory which claims to conform to this ATS specification shall use a MOT which conforms to this ATS.

Annex A (normative):
End-to-end 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 Guidance for completing the ICS proforma
A.1.1 Purposes and structure
The purpose of this ICS proforma is to provide a mechanism whereby a supplier of an implementation of the
requirements defined by ETSI for the network side for the pan-European Integrated Services Digital Network (ISDN),
may provide information about the implementation in a standardized manner.
The proforma is subdivided into subclauses for the following categories of information:
- guidance for completing the proformas;
- identification of the implementation;
- global statement of conformance.
A.1.2 Abbreviations and conventions
The ICS proforma contained in the annex A is comprised of information in tabular form in accordance with the
guidelines presented in ISO/IEC 9646-7.
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?".
Status column
The following notations, defined in ISO/IEC 9646-7, 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;
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 an unique conditional status
expression which is defined immediately following the table.
ETSI
16 ETSI EG 201 299-2 V2.1.1 (2000-03)
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, 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).
It is also possible to provide a comment to an answer in the space provided at the bottom of the table.
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.
A.1.3 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 or supported column boxes provided, using the notation
described in subclause A.1.2.
If necessary, the supplier may provide additional comments in space at the bottom of the tables, or separately on sheets
of paper.
More detailed instructions may be given at the beginning of the different subclauses of the ICS proforma.
