1 Scope
The present document specifies the network Test Suite Structure and Test Purposes (TSS&TP) for the T reference point
or coincident S and T reference point (as defined in ITU-T Recommendation I.411 [9]) of implementations conforming
to the standards for the signalling network layer for circuit-mode basic call control of the Digital Subscriber Signalling
System No. one (DSS1) protocol for the pan-European Integrated Services Digital Network (ISDN), EN 300 403-1 [1]
and ETS 300 403-2 [2].
A further part of the present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation
eXtra Information for Testing (PIXIT) proforma based on the present document. Other parts specify the TSS&TP and
the ATS and partial PIXIT proforma for the User side of the T reference point or coincident S and T reference point of
implementations conforming to EN 300 403-1 [1] and ETS 300 403-2 [2].

3 Definitions and abbreviations
3.1 Definitions
3.1.1 Definitions related to conformance testing
For the purposes of the present document, the following terms and definitions apply, in addition to those given in
EN 300 403-1 [1].
abstract test case: refer to ISO/IEC 9646-1 [4].
Abstract Test Method (ATM): refer to ISO/IEC 9646-1 [4].
Abstract Test Suite (ATS): refer to ISO/IEC 9646-1 [4].
active test: test case where the IUT is required to send a particular message, but not in reaction to a received message.
This would usually involve the use of PIXIT information to see how this message can be generated and quite often is
specified in an ATS using an implicit send event.
Implementation Under Test (IUT): refer to ISO/IEC 9646-1 [4].
implicit send event: refer to ISO/IEC 9646-3 [6].
lower tester: refer to ISO/IEC 9646-1 [4].
passive test: test case where the IUT is required to respond to a protocol event (e.g. received message) with another
protocol event (sends message) and which normally does not require any special operator intervention such as is
associated with the implicit send event.
point of control and observation: refer to ISO/IEC 9646-1 [4].
Protocol Implementation Conformance Statement (PICS): refer to ISO/IEC 9646-1 [4].
PICS proforma: refer to ISO/IEC 9646-1 [4].
Protocol Implementation eXtra Information for Testing (PIXIT): refer to ISO/IEC 9646-1 [4].
PIXIT proforma: refer to ISO/IEC 9646-1 [4].
system under test: refer to ISO/IEC 9646-1 [4].
Test Purpose (TP): refer to ISO/IEC 9646-1 [4].
3.1.2 Definitions related to EN 300 403-1
Integrated Services Digital Network (ISDN): see ITU-T Recommendation I.112 [8], definition 308.
ISDN number: number conforming to the numbering and structure specified in ITU-T Recommendation E.164 [7].
network: DSS1 protocol entity at the Network side of the user-network interface where a T reference point or
coincident S and T reference point applies.
network (S/T): DSS1 protocol entity at the Network side of the user-network interface where a coincident S and T
reference point applies.
network (T): DSS1 protocol entity at the Network side of the user-network interface where a T reference point applies
(user is the private ISDN).
