Foreword
The second part of this Interim European Telecommunication Standard (I-ETS) has been produced by the
Terminal Equipment (TE) Technical Committee of the European Telecommunications Standards Institute
(ETSI).
An ETSI standard may be given I-ETS status either because it is regarded as a provisional solution ahead
of a more advanced standard, or because it is immature and requires a "trial period". The life of an I-ETS
is limited to three years after which it can be converted into an ETS, have its life extended for a further two
years, be replaced by a new version, or be withdrawn.
This is the second part of a I-ETS which comprises four Parts:
"Integrated Services Digital Network (ISDN); Conformance testing for the Euro-ISDN Programming
Communication Interface (PCI);
Part 1: "Test Suite Structure and Test Purposes (TSS&TP) for the PCI User Facility (PUF);
Part 2: "Abstract Test Suite (ATS) for the PCI User Facility (PUF);
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) for the Network Access Facility (NAF);
Part 4: "Abstract Test Suite (ATS) for the Network Access Facility (NAF)".
Annexes A, B and C to this part of the I-ETS are normative whereas annex D is informative.
Announcement date
Date of adoption of this I-ETS: 6 March 1998
Date of latest announcement of this I-ETS (doa): 30 June 1998
Introduction
I-ETS 300 697, Parts 1 to 4 comprises the Test Suite Structure and Test Purposes (TSS&TP) and the
Abstract Test Suites (ATS) to ETS 300 325 [1]. The Euro-ISDN PCI is a PCI which provides access to the
Euro-ISDN. The basic model of the ISDN PCI consists of two entities, a service user called the PCI User
Facility (PUF) and a service provider called the Network Access Facility (NAF). For the purpose of
conformance testing, the PUF and the NAF are treated separately. This is because the PUF manufacturer
and the NAF manufacturer may be completely different and their testing needs should be treated
separately. Each part is tested to ensure that they each meet the conformance requirements of the ETS
and to increase their probability of inter-operating. This is the reason why a separate TSS&TP and a
separate ATS has been produced for each of the PCI User Facility (PUF) and the Network Access Facility
(NAF).
All Parts have been produced according to ISO/IEC 9646 [2, 3, 4, 5, 6] and ETS 300 406 [8].
As stated above, this I-ETS is structured in four parts:
- part 1 contains the TSS&TP for the PUF;
- part 2 contains the ATS for the PUF;
- part 3 contains the TSS&TP for the NAF;
- part 4 contains the ATS for the NAF.

Part 1 (TSS&TP for the PUF) contains all Test Purposes (TPs) for the PUF (PCI messages). It describes
what is covered by the TPs for the PUF and what areas of the ETS are not covered. The Test Suite
Structure is described and the convention followed in naming the TPs is described. A list of basic
interconnection tests is given.
This second Part of the I-ETS (ATS for the PUF) contains the ATS for the PUF (PCI messages). The
test method used is described in detail and diagrams explaining the test method are presented. The
reasons for choosing that test method are also given. The ATS is written in Tree and Tabular Combined
Notation language (TTCN) and the TTCN is contained in annex A. Annex B contains the Protocol
Conformance Test Report (PCTR), annex C contains the Implementation eXtra Information for Testing
(IXIT) and annex D contains an Implementation Conformance Statement (ICS).
Part 3 (TSS&TP for the NAF) contains all the TPs for the NAF (PCI messages and Exchange
Mechanism). It describes what is covered by the TPs for the NAF and what areas of the ETS are not
covered. The TSS is described and the TPs are given. A list of basic interconnection tests is given.
Part 4 (ATS for the NAF) contains the ATS for the NAF (PCI messages and Exchange Mechanism). The
test method used is described in detail and a diagram explaining the test method is given. The reasons for
choosing that test method is also given. The ATS is written in concurrent TTCN and the TTCN is
contained in annex A. Annex B contains the PCTR, annex C contains the IXIT and annex D contains an
ICS.
NOTE: The ICS in annexes D of part 2 and part 4 are informative as ETS 300 325 [1] already
contains an ICS. However, the ICS in ETS 300 325 [1] is not adequate for these ATSs
and should eventually be replaced by annex D of part 2 and part 4.

Part 2 of this I-ETS contains the Abstract Test Suite (ATS) for the PUF (PCI messages). The test method
used is described in detail and diagrams explaining the test method are presented. The reasons for
choosing this test method are also given. The Abstract Test Suite is written in TTCN and the TTCN is
contained in annex A. Annex B contains the PCTR, annex C contains the IXIT and annex D contains an

4 General constraints for testing and applicable test methods
4.1 Testing model
A Euro-ISDN PCI is an interface and not a protocol standard. ISO/IEC 9646-2 [3] explicitly states that it
applies only to protocols of the Open Systems Interconnection (OSI) stack. This means that
ISO/IEC 9646-3 [4] cannot be used directly for testing ETS 300 325 [1]. This is why, whilst testing, the
layer model is applied to the EURO-ISDN PCI even though this notion does not exist in the ETS itself.
In the EURO-ISDN PCI, it is as if the Exchange Mechanism is a layer below the three planes,
Administration, Control and User. The Exchange Mechanism transports the messages
