1 Scope
This European Telecommunication Standard (ETS) contains the Abstract Test Suite (ATS) specification
for the core part of the Generic Functional Protocol (GFP) for the support of supplementary services of the
Inter-exchange signalling protocol, for Private Integrated Services Networks (PISN).
The core part of the GFP excludes the connectionless Application Packet Data Unit (APDU) transport
mechanism, the Data Service Element (DSE) protocol, the Application Control Service Element (ACSE)
protocol, procedures for carrying manufacturer specific information and requirements only relevant to
Originating PINXs for calls and Call Independent Signalling Connections (CISCs) or source PINXs for
APDUs and notifications.
The objective of this ETS is to provide conformance tests which give a high probability of inter-operability.
This ETS covers the core part of the procedures described in ETS 300 239 [1].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [5], ISO/IEC 9646-2 [6]
and ISO/IEC 9646-3 [7] including Amendment 1 [8]) is used as basis for the test methodology.
This ETS is applicable to implementations which support either a Basic Rate (BR) or a Primary Rate
Access (PRA) interface, or both, operating over a leased line. It is applicable to PINXs acting as both
transit or end PINXs for calls and Call Related Signalling Connections (CRSC), however it does not
include test cases applicable to end PINXs acting as source or originating PINXs.
Annex A provides the Partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma of
this ETS.
Annex B provides the Protocol Conformance Test Report (PCTR) proforma of this ETS.
Annex C provides the Tree and Tabular Combined Notation (TTCN) part of this ETS.

4 Abstract Test Method (ATM)
This clause describes the different ATMs used for testing the GFP. Two methods are applied; the Remote
test method, and the Multi-Party test method.
4.1 Choice of the ATM
4.1.1 Functional subsets
The GFP is divided into a number of entities as shown in figure 1. This ATS is principally concerned with
the testing of the Protocol Control (PC) and Generic Functional Transport Control (GFTC) entities,
however it also contains Test Cases (TCs) concerning some error handling functions of the Co-ordination
and ROSE entities.
NOTE: Valid behaviour of the application layer is supplementary service specific and its testing
is specified in test specifications for individual supplementary services (if any). DSE
requirements are excluded from the scope of this ETS.
The testing of all these layers is performed using a PCO at the SCM/Network layer boundary.

4.1.2 PINX Role and Test Component Configuration considerations
A PINX may act either in the role of an End PINX or in the role of a Transit PINX in the context of each
Basic Call or CISC. A particular PINX may be capable of acting in one or both roles. Whereas the Generic
Functional Transport Control (GFTC) requirements generally depend on which role is involved, the
Protocol Control (PC) requirements do not.
Depending on the role of the PINX, it may be necessary to use different procedures in the preambles to
achieve the pre-condition in some TPs concerned with PC requirements. For these cases, which will
require different test component configurations, there may be two separate Test Cases (TCs), one for
each role, generated from each relevant TP.
4.2 Single PCO testing
Single PCO testing applies to all aspects of the testing of the IUT as an End PINX. It is also used for those
tests as a Transit PINX when events at the outgoing side are not required to be tested and when no
activity is expected at the outgoing side, i.e. only one interface is reacting.
4.2.1 Testing of End PINX and Transit PINX (single Transit interface active)
As shown in figure 2, the ROSE, Co-ordination Function (CF), GFTC and Protocol Control (PC) part, is
considered to be the IUT, and an end-system. It is not possible to observe and control the upper service
boundary of the IUT. Consequently, the test method chosen is the Remote Test Method, where the co-
ordination procedures are expressed in an informal way. The test system will only contain one LT and no
UT. The PCO, called LX, is located between the ROSE, Co-ordination Function, Generic Functional
Transport Control and Protocol Control part, and the segmentation part. Only unsegmented Protocol Data
Units (PDUs) are exchanged.

4.3 Multiple PCO testing
Multiple PCO testing applies to the testing of the IUT as a transit PINX, except for tests were no events on
the outgoing side are expected. The two interfaces are active.
4.3.1 Testing of transit PINX (dual transit interfaces active)
As shown in figure 3, the ROSE, CF, GFTC and PC part is considered to be the IUT, and is an open-relay
system. Consequently, the test method chosen is a multi-party test method with no UT. The test system
will contain two LTs attached to the IUT via two PCOs, called LX and LY, located between the ROSE, CF
and PCl part, and the segmentation part. The PDUs exchanged are only unsegmented PDUs.

4.4 Test configurations and use of concurrent TTCN
As this ATS covers both single-party testing using non-concurrent TTCN, and multi-party testing using
concurrent TTCN, the notation chosen for the complete ATS is the concurrent TTCN syntax. Therefore,
test components are defined to describe the two configurations: the "mono" configuration, and the "transit"
configuration, as shown in figure 4 and 5.
The mono configuration is used in case of single-party testing, i.e. for the following:
- ROSE testing;
- CF testing;
- GFTC testing;
- PC testing,
for End PINX and Transit PINX (single Transit interface active).
Only one test component, which is the Master Test Component MTC_MONO, connected to the IUT via
the PCO LX, is needed in this case.

The transit configuration is used in case of multi-party testing, i.e. for the following:
- ROSE testing;
- CF testing;
- GFTC testing;
- PC testing,
for transit PINX (dual transit interfaces active).
In this case, three test components are needed, these are the Master Test Component MTC_TRANSIT,
and the two Parallel Test Components PTC_X and PTC_Y, which are connected to the Master Test
Component via the two Co-ordination Points CPX and CPY. PTC_X and PTC_Y are further connected to
the IUT via the two PCOs LX and LY.

Due to the ATMs chosen in this ATS or other restrictions, the following test purposes have been identified
as being untestable, and therefore have not been derived into test cases.
