Page 7ETS 300 267-3: May 1997ForewordThis European Telecommunication Standard (ETS) has been produced by the Signalling Protocols andSwitching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS is part 3 of a multi-part standard covering the Digital Subscriber Signalling System No. one(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) telephony 7 kHz andvideotelephony teleservices, as described below:Part 1:"Protocol specification";Part 2:"Protocol Implementation Conformance Statement (PICS) proforma specification";Part 3:"Test Suite Structure and Test Purposes (TSS&TP) specification for the user";Part 4:"Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing(PIXIT) proforma specification for the user";Part 5:"TSS&TP specification for the network";Part 6:"ATS and partial PIXIT proforma specification for the network".Transposition datesDate of adoption:23 May 1997Date of latest announcement of this ETS (doa):31 August 1997Date of latest publication of new National Standardor endorsement of this ETS (dop/e):28 February 1998Date of withdrawal of any conflicting National Standard (dow):28 February 1998IntroductionThis ETS is divided into seven clauses. Clauses 1 to 3 form the scope, references and abbreviations.Clause 4 contains the test suite structure. Clause 5 contains the complete list of test purposes. Clause 6contains the list of combined test purposes, i.e. test purposes which can be tested together in one testcase. Clause 7 contains the requirements for a generic or abstract test suite to comply with this ETS.It is been assumed that the Implementation Under Test (IUT) already complies with the conformancerequirements associated with the ISDN basic call as defined in ETS 300 102-1. This is specified as arequirement in ETS 300 267-2, clause 5. ETS 300 267-1, subclause 5.1, states that the additional genericrequirements of clause 5 are defined to be compatible with the existing requirements of ETS 300 102-1.The following approach is adopted with regard to specifying test purposes:-resultant states of the IUT are not checked following receipt of messages which comply withETS 300 102-1. Resultant states of the IUT are checked following receipt of messages which donot comply with ETS 300 102-1, e.g. a CONNECT message which contains a Bearer capabilityinformation element;-for ETS 300 267-1, clause 5, the use of the word "assumes", in the case of an IUT at the originatinginterface, is interpreted as meaning that the IUT checks in-band: such test purposes are applicable,therefore, only to IUTs which contain in-band entities.In cases where ETS 300 267-1 specifies that requirements in ETS 300 102-1 shall apply, it is assumedthat, because the IUT already complies with ETS 300 102-1, it also complies with these requirements.However, when specifying the abstract test cases, including test case selection, the requirements inETS 300 102-1 need to be taken into account.SIST ETS 300 267-3:1998

Page 9ETS 300 267-3: May 19971ScopeThis third part of ETS 300 267 is applicable to the stage three of the telephony 7 kHz and videotelephonyteleservices for the pan-European Integrated Services Digital Network (ISDN) as provided by Europeanpublic telecommunications operators at the T reference point or coincident S and T reference point (asspecified in ITU-T Recommendation I.411 [11] by means of the Digital Subscriber Signalling SystemNo. one (DSS1) protocol. ETS 300 267-1 [5] provides the protocol specification and ETS 300 267-2 [6] theProtocol Implementation Conformance Statement (PICS) proforma specification. Stage three identifies theprotocol procedures and switching functions needed to support a telecommunications service (see CCITTRecommendation I.130 [10]).This ETS provides the Test Suite Structure and Test Purposes (TSS&TP) for the user side. It covers theprotocol requirements as defined in ETS 300 267-1 [5] and provides test purposes for the additionalgeneric requirements for basic telecommunication services not defined in ETS 300 102-1 [2](ETS 300 267-1 [5], clause 5), for the telephony 7 kHz teleservice (ETS 300 267-1 [5], clause 6) and forthe videotelephony teleservice (ETS 300 267-1 [5], clause 7).Two types of implementations are covered:-an implementation which supports user requirements at the coincident S and T reference point;-an implementation which supports user requirements for interworking with private ISDNs at theT reference point.2Normative referencesThis ETS incorporates by dated or undated references, provisions from other publications.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 3 of a multi-part standard covering the Digital Subscriber Signalling System No. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) telephony 7 kHz and
videotelephony teleservices, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 5: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".

Introduction
This ETS is divided into seven clauses. Clauses 1 to 3 form the scope, references and abbreviations.
Clause 4 contains the test suite structure. Clause 5 contains the complete list of test purposes. Clause 6
contains the list of combined test purposes, i.e. test purposes which can be tested together in one test
case. Clause 7 contains the requirements for a generic or abstract test suite to comply with this ETS.
It is been assumed that the Implementation Under Test (IUT) already complies with the conformance
requirements associated with the ISDN basic call as defined in ETS 300 102-1. This is specified as a
requirement in ETS 300 267-2, clause 5. ETS 300 267-1, subclause 5.1, states that the additional generic
requirements of clause 5 are defined to be compatible with the existing requirements of ETS 300 102-1.
The following approach is adopted with regard to specifying test purposes:
- resultant states of the IUT are not checked following receipt of messages which comply with
ETS 300 102-1. Resultant states of the IUT are checked following receipt of messages which do
not comply with ETS 300 102-1, e.g. a CONNECT message which contains a Bearer capability
information element;
- for ETS 300 267-1, clause 5, the use of the word "assumes", in the case of an IUT at the originating
interface, is interpreted as meaning that the IUT checks in-band: such test purposes are applicable,
therefore, only to IUTs which contain in-band entities.
In cases where ETS 300 267-1 specifies that requirements in ETS 300 102-1 shall apply, it is assumed
that, because the IUT already complies with ETS 300 102-1, it also complies with these requirements.
However, when specifying the abstract test cases, including test case selection, the requirements in
ETS 300 102-1 need to be taken into account.

1 Scope
This third part of ETS 300 267 is applicable to the stage three of the telephony 7 kHz and videotelephony
teleservices for the pan-European Integrated Services Digital Network (ISDN) as provided by European
public telecommunications operators at the T reference point or coincident S and T reference point (as
specified in ITU-T Recommendation I.411 [11] by means of the Digital Subscriber Signalling System
No. one (DSS1) protocol. ETS 300 267-1 [5] provides the protocol specification and ETS 300 267-2 [6] the
Protocol Implementation Conformance Statement (PICS) proforma specification. Stage three identifies the
protocol procedures and switching functions needed to support a telecommunications service (see CCITT
Recommendation I.130 [10]).
This ETS provides the Test Suite Structure and Test Purposes (TSS&TP) for the user side. It covers the
protocol requirements as defined in ETS 300 267-1 [5] and provides test purposes for the additional
generic requirements for basic telecommunication services not defined in ETS 300 102-1 [2]
(ETS 300 267-1 [5], clause 5), for the telephony 7 kHz teleservice (ETS 300 267-1 [5], clause 6) and for
the videotelephony teleservice (ETS 300 267-1 [5], clause 7).
Two types of implementations are covered:
- an implementation which supports user requirements at the coincident S and T reference point;
- an implementation which supports user requirements for interworking with private ISDNs at the
T reference point.

4 Test Suite Structure (TSS)
The test suite is structured as a tree. Six test group levels are defined. The TSS is depicted in figure 1.
4.1 First test group level
The first test group level contains the name of the test suite:
UT7V User side telephony 7 kHz, videotelephony teleservices and generic protocol.
4.2 Second test group level
The second test group level indicates whether the IUT is the calling or the called terminal:
ORIG Calling User Interface;
DEST Called User Interface.
4.3 Third test group level
The third test group level indicates whether the test purpose covers a requirement applicable to valid
behaviour, to invalid behaviour or to inopportune behaviour:
BV Valid behaviour test purpose;
BI Invalid Behaviour test purpose;
BO inOpportune Behaviour test purpose.
4.4 Fourth test group level
The fourth test group level indicates whether the test purpose covers a requirement applicable to the
generic protocol, the telephony 7 kHz protocol, or the videotelephony teleservice protocol:
GEN Generic requirements. The test purpose covers a requirement applicable for the
generic part of ETS 300 267-1 [5] (clause 5);
TL7 Telephony 7 kHz teleservice. The test purpose covers a requirement applicable for the
telephony 7 kHz part of ETS 300 267-1 [5] (clause 6);
VTL Videotelephony teleservice. The test purpose covers a requirement applicable for the
videotelephony part of ETS 300 267-1 [5] (clause 7).
The group for generic requirements does not appear in the TSS of the combined test purposes. None of
the generic test purposes can be considered as testable.

Page 13
ETS 300 267-3: May 1997
4.5 Fifth test group level
The fifth test group level indicates which kind of functionality is tested and, more precisely, whether the
test purposes cover requirements applicable to fallback allowed, fallback not allowed or connection
management. Three groups are defined:
FBA FallBack Allowed: this group covers all tests where a fallback allowed SETUP
message is sent to the IUT;
FBN FallBack Not allowed: this group covers all tests where a fallback not allowed SETUP
message is sent to the IUT;
CMN Connection MaNagement: this group includes all other cases which do not test the
response to or the sending of a fallback allowed or a fallback not allowed SETUP
message. As a consequence, the clearing of a call and the establishment of a second
connection for videotelephony is tested here.

4.6 Sixth test group level
The sixth test group level indicates the type of implementation to which the test purpose applies:
ST An implementation which supports user requirements at the coincident S and
T reference point;
PT An implementation which supports user requirements for interworking with private
ISDNs at the T reference point;
ST_T An implementation which supports user requirements at the coincident S and
T reference point or user requirements for interworking with private ISDNs at the
T reference point.
The TSS for combined test purposes, described in clause 6, neither contains groups that include only
untestable test purposes nor the sixth test group level due to the fact that combined test purposes contain
combinations of both ST, ST_T and PT test purposes.
5 Test purposes for generic requirements, telephony 7 kHz and video-
telephony teleservices
5.1 Test purpose format
The structure of a test purpose identifier is defined in table 1.

Cross reference GTP/TTP/VTP cross reference data.
Comments Any relevant comments.
The "Other relevant reference" field, where applicable, contains a reference to a specification document
containing the whole, or part, of the requirement to be tested by the test purpose.
The "Selection criteria" field consists of a Boolean expression incorporating items from ETS 300 267-2 [6]
(in which case items are not prefixed by a reference number) and from I-ETS 300 314 [8].

Page 15
ETS 300 267-3: May 1997
Some of the telephony 7 kHz or videotelephony test purposes are directly related, but not identical, to
generic ones. Where such a relationship exists, the reference to the related generic test purpose is
specified in the "Cross reference" field of the telephony 7 kHz or videotelephony test purpose.
Untestable test purposes are listed using italic font. Test purposes for generic protocol requirements
which correspond to no particular IUT have been considered as untestable. Test purposes which test an
unframed mode in the B-channel or an internal behaviour of the IUT have also been considered as
untestable.
