1 Scope
This thirty-sixth part of ETS 300 356 provides the conformance test specification for the ISDN User Part
(ISUP) version 2 supplementary services defined in ETS 300 356-2 [2] to ETS 300 356-19 [18] in
compliance with the relevant requirements and in accordance with the relevant guidance given in
ISO/IEC 9646-1 [23].
This ETS contains the Abstract Test Suite (ATS) for ISUP version 2 supplementary services, written in
Tree and Tabular Combined Notation (TTCN) as specified in ISO/IEC 9646-3 [25]. It is based on
ETS 300 356-35 [20] which specifies the Test Suite Structure and Test Purposes (TSS&TP).
This ETS applies only to exchanges having implemented the ISUP version 2 protocol specifications [2-18].
It is applicable for conformance testing of all types of exchanges as specified in the ISUP version 2
protocol specifications [2-18]. This ETS does not deal with compatibility testing.
The main text part of this ETS presents the requirements regarding the chosen test method and the
conventions used within the ATS.
The annexes contain the ATS for ISUP version 2 supplementary services (available on electronic media),
the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma and the Protocol
Conformance Test Report (PCTR) proforma.
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
- terms defined in the ISUP version 2 reference specifications [1-18];
- terms defined in ISO/IEC 9646-1 [23] and in ISO/IEC 9646-3 [25].
In particular, the following terms apply:
Abstract Test Case (ATC): A complete and independent specification of the actions required to achieve a
specific test purpose, defined at the level of abstraction of a particular Abstract Test Method, starting in a
stable testing state and ending in a stable testing state (see ISO/IEC 9646-1 [23], subclause 3.3.3).
Abstract Test Method (ATM): The description of how an IUT is to be tested, given at an appropriate level
of abstraction to make the description independent of any particular realization of a Means of Testing, but
with enough detail to enable abstract test cases to be specified for this method (see ISO/IEC 9646-1 [23],
subclause 3.3.5).
Abstract Test Suite (ATS): A test suite composed of abstract test cases (see ISO/IEC 9646-1 [23],
subclause 3.3.6).
Implementation Under Test (IUT): An implementation of one or more OSI protocols in an adjacent
user/provider relationship, being part of a real open system which is to be studied by testing (see
ISO/IEC 9646-1 [23], subclause 3.3.43).
Means Of Testing (MOT): The combination of equipment and procedures that can perform the
derivation, selection, parametrization and execution of test cases, in conformance with a reference
standardized ATS, and can produce a conformance log (see ISO/IEC 9646-1 [23], subclause 3.3.54).

test events is to be controlled and observed, as defined in an abstract test method (see
ISO/IEC 9646-1 [23], subclause 3.3.64).
pre-test condition: A setting or state in the IUT which cannot be achieved by providing stimulus from the
test environment.
Protocol Implementation Conformance Statement (PICS): A statement made by the supplier of a
protocol claimed to conform to a given specification, stating which capabilities have been implemented
(see ISO/IEC 9646-1 [23], subclauses 3.3.39 and 3.3.80).
PICS proforma: A document, in the form of a questionnaire, which when completed for an
implementation or system becomes the PICS.
Protocol Implementation eXtra Information for Testing (PIXIT): A statement made by a supplier or
implementor of an IUT (protocol) which contains or references all of the information related to the IUT and
its testing environment, which will enable the test laboratory to run an appropriate test suite against the
IUT (see ISO/IEC 9646-1 [23], subclauses 3.3.41 and 3.3.81).
PIXIT proforma: A document, in the form of a questionnaire, which when completed for the IUT becomes
the PIXIT.
System Under Test (SUT): The real open system in which the IUT resides (see ISO/IEC 9646-1 [23],

4.1 Identification of the system and implementation under test
The System Under Test (SUT) is an exchange. The Implementation Under Test (IUT) is the ISUP
version 2 implementation in this exchange, mainly the part responsible for the supplementary services
functionality, as shown in figure 1.

The ISUP signalling protocol can be observed on the SS7 link on the Network-Network Interface (NNI).
The effects of signalling procedures of ISUP can be observed on the circuits controlled by the ISUP on the
NNI.
The ISUP implementation will in some exchanges have to interwork with the Access signalling system on
the User-Network Interface (UNI) and involve call handling in order to establish end-to-end connections.

Figure 2: Roles of exchanges
The exchanges can be divided in two main groups according to their functionality: local exchanges, where
calls originate and terminate, and intermediate exchanges, with transit functionality. Local exchanges are
national, i.e. belong to a national network. Intermediate exchanges are national or international. The
international intermediate exchanges which permit access to the international network are the gateway
exchanges (incoming and outgoing), also called International Switching Centres (ISCs). A particularity for
some supplementary services, e.g. call diversion services, is that a local exchange is not only
originator/terminator of the call but also mediator between two far-end local exchanges.
The roles of the exchanges are summarized in table 1.

4.2 ATM and testing configuration for ISUP version 2
The Abstract Test Method (ATM) chosen for the ISUP version 2 supplementary services testing
specification is the distributed multi-party 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 IUT.
The testing architectures are described in the foll

Page 7ETS 300 356-36: March 19981ScopeThis thirty-sixth part of ETS 300 356 provides the conformance test specification for the ISDN User Part(ISUP) version 2 supplementary services defined in ETS 300 356-2 [2] to ETS 300 356-19 [18] incompliance with the relevant requirements and in accordance with the relevant guidance given inISO/IEC 9646-1 [23].This ETS contains the Abstract Test Suite (ATS) for ISUP version 2 supplementary services, written inTree and Tabular Combined Notation (TTCN) as specified in ISO/IEC 9646-3 [25]. It is based onETS 300 356-35 [20] which specifies the Test Suite Structure and Test Purposes (TSS&TP).This ETS applies only to exchanges having implemented the ISUP version 2 protocol specifications [2-18].It is applicable for conformance testing of all types of exchanges as specified in the ISUP version 2protocol specifications [2-18]. This ETS does not deal with compatibility testing.The main text part of this ETS presents the requirements regarding the chosen test method and theconventions used within the ATS.The annexes contain the ATS for ISUP version 2 supplementary services (available on electronic media),the partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma and the ProtocolConformance Test Report (PCTR) proforma.2Normative referencesThis ETS incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publicationsapply to this ETS only when incorporated in it by amendment or revision. For undated references the latestedition of the publication referred to applies.An ETS is referenced where it (partly) overrides the corresponding ITU-T Recommendation or where acorresponding ITU-T Recommendation does not exist (yet).

Local exchanges arenational, i.e. belong to a national network. Intermediate exchanges are national or international. Theinternational intermediate exchanges which permit access to the international network are the gatewayexchanges (incoming and outgoing), also called International Switching Centres (ISCs). A particularity forsome supplementary services, e.g. call diversion services, is that a local exchange is not onlyoriginator/terminator of the call but also mediator between two far-end local exchanges.The roles of the exchanges are summarized in table 1.Table 1: Roles of exchangesLocalIntermediate exchangeexchangeNationalInternationalOriginating Local ExchangeOLETransit ExchangeNTEITEIncoming/Gateway ExchangeIncIEOutgoing/Gateway ExchangeOutIEDestination Local ExchangeDLE4.2ATM and testing configuration for ISUP version 2The Abstract Test Method (ATM) chosen for the ISUP version 2 supplementary services testingspecification is the distributed multi-party test method. The ATM is defined at an appropriate level ofabstraction so that the test cases may be specified appropriately, without adding restrictions to the IUT.The testing architectures are described in the following subclauses.The ATS is written in concurrent TTCN.SIST ETS 300 356-36:1999
