1 Scope
This third part of ETS 300 009 specifies the Abstract Test Suite (ATS) and partial Protocol Implementation
eXtra Information for Testing (PIXIT) proforma for the Signalling Connection Control Part (SCCP) for
implementations conforming to ITU-T Recommendations Q.711 to Q.714 and Q.716 as modified by
ETS 300 009-1 [1]. The Test Suite Structure and Test Purposes (TSS&TP) related to this ATS and partial
PIXIT proforma specification are specified in annex B and C of the present document.
The test cases validate Classes 0, 1 and 2 SCCP procedures by monitoring and analysing SCCP
messages and their contents.
Testing of SCCP connection-oriented protocol Class 3 is out of the scope of this ETS.
ISO/IEC 9646-1 [4], ISO/IEC 9646-2 [5], ISO/IEC 9646-3 [6], ISO/IEC 9646-4 [7] and ISO/IEC 9646-5 [8]
and ETS 300 406 [3] are used as the basis for the test methodology.

4 Abstract test method
4.1 Description of ATMs used
Within this ATS, two ATMs are used. These are the RS and the YT test methods. Their applicability
depends on the IUT's functionality and capabilities.
Some of the described tests may not be required to be executed since the respective functionality is not
included in the IUT (the implemented functionalities should be described in the completed PICS proforma,
see EN 300 009-2 [2]). In such a case, the non-execution of these specific tests should not be regarded
as a non-conformance statement.
IUTs which are to be tested using this ATS are required to have previously been tested for conformity
against and passed the test suites for ETS 300 008-1 [10].
4.2 Conventions for test components and PCOs
SCCP communication is required between the SPs used in the test configurations. Two configurations are
required to perform all these tests. It should be possible that a SP can be a primary/backup node for
another SP. Furthermore, it should be possible that the SPs contain concerned SSs. All SPs should be in
the same MTP network. There should be one SPC for the IUT (SP A), containing two different SSNs, and
two SPCs, with one SSN each, for each test component (SP B, SP C).

Page 10
ETS 300 009-3: January 2000
SP_B and SP_C contain LTs B and C, respectively. An operator above the IUT is required in some cases
to answer to implicit send requesting the emission of messages or to apply MA command on the
configuration of the SUT. The MA procedures are requested with message including MML commands.
The contents of those message have to be fulfilled in this PIXIT and depends of the IUT. The lower
interface of the IUT is reached via the LTs and the service provider. LT_B, LT_C, SUT_MML are all
PCOs.
The ATS is based on multi party test method. Thus the test system is made up one Main Test Component
(MTC) and eventually a Parallel Test Component (PTC) in test configuration for relay node.

4.3 The remote single layer test method
SP A is the SUT and requires in case of the RS method needs no additional requirements from the SUT.
However, sometimes a SCCP operator should be available to trigger the IUT and to apply requested
command (MML). The arrows in figure 2 indicate an SCCP relation.

4.4 The relay transverse ATM
SP A is the SUT and is used as a relay point (see figure 3). The arrows indicate an SCCP relation. All SPs
are in the same MTP network. MTC and PTC synchronized themselves by exchanging message at
co-ordination point CP_B_C. The test case is stopped and the final verdict is set by the MTC.

5 Untestable Test purposes
No upper tester has been defined in the standard protocol. Consequently, test purposes that cannot be
tested without upper tester have been considered as untestable. This concerns mainly test purpose that
check local procedure or the behaviour of the IUT concerning the use SCCP's ASP.

B.6.4 Routing information
Ideally, for a complete configuration, there should be one SPC for the IUT, containing two different SSNs,
and two SPCs (with one SSN each) for the test system (testing the aspects of network border crossing is
for further study). PC A is assumed to be the IUT and PC B and PC C are assumed to be part of the test
system as described in the configuration scheme (see clause 5, figures 1 to 3). When only end node
configuration is tested, RT information concerning SP C has not to be valued. SSN A1 and SSN A2 in the
ATS are supposed to answer automatically to a CR with a CC.

B.6.4.2 Signalling link selection
The SLS is not normally fixed but is assigned at random between (0.15) by MTP-users. However, for the
purposes of performing tests, the supplier of the SUT and/or the test laboratory may wish to specify the
SLS codes used by the tester. If these fields are left blank by the client then the test laboratory will
determine the SLS codes used by the tester.
