For the purposes of the present document, the terms and definitions given in SIP/ISUP interworking reference
specification, in ISDN layer 3 reference specification, in ISO/IEC 9646-1 [8], in ISO/IEC 9646-3 [9], in
ISO/IEC 9646-7 [10] and the following apply:
Abstract Test Case (ATC): 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
Abstract Test Method (ATM): description of how an SUT 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
Abstract Test Suite (ATS): test suite composed of abstract test cases
Implementation Under Test (IUT): 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
ETSI

---------------------- Page: 7 ----------------------
8 ETSI TS 186 002-2 V1.1.5 (2008-05)
Means of Testing (MOT): combination of equipment and procedures that can perform the derivation, selection,
parameterization and execution of test cases, in conformance with a reference standardized ATS, and can produce a
conformance log
PICS proforma: document, in the form of a questionnaire, which when completed for an implementation or system
becomes the PICS
PIXIT proforma: document, in the form of a questionnaire, which when completed for the SUT becomes the PIXIT
Point of Control and Observation (PCO): point within a testing environment where the occurrence of test events is to
be controlled and observed, as defined in an Abstract Test Method
Pre-test condition: setting or state in the SUT which cannot be achieved by providing stimulus from the test
environment
Protocol Implementation Conformance Statement (PICS): statement made by the supplier of a protocol claimed to
conform to a given specification, stating which capabilities have been implemented
Protocol Implementation eXtra Information for Testing (PIXIT): statement made by a supplier or implementor of
an SUT (protocol) which contains or references all of the information related to the SUT and its testing environment,
which will enable the test laboratory to run an appropriate test suite against the SUT
SIP number: number conforming to the numbering and structure specified in ITU-T Recommendation E.164 [11]
System Under Test (SUT): real open system in which the SUT resides
User: access protocol entity at the User side of the user-network interface where a T reference point or coincident S and
T reference point applies
