4 Test architecture 4.1 Abstract Test Method (ATM) This clause describes the ATM used for testing the INAP protocol. It is the embedded variant of the remote test method used in Multy Party Testing (MPyT) context, as defined in ISO/IEC 9646-2 [5]. This test method has been selected, because: - this test method implies no specific requirements from the Implementation Under Test (IUT); - the upper Service Access Point (SAP) of the IUT cannot be directly observed; - this test method places minimum limitations in the realization of conformance testing. 4.2 Overall configuration Figure 1 describes the test architecture which will be used for the definition of the ATS. A single test architecture covers all testing configuration requirements.

The same architecture can be used for testing several interfaces. The roles of IUT and LTs change according to the protocol to be tested in the IUT. Table 1 gives the nature of the IUT and LTs according to the protocol under test.

4.3 Test of SSF-SCF interface using INAP The test program contains the program of the main LT1 main tester as well as the co-ordination points to co-ordinate the tasks with the other testers LT2 and LT3. IUT: Is the SSF-INAP. LT1: Test program is the SCF. LT2: Test program is the SRF-INAP when required. LT3: Informal test program for actions and observation at the signalling control points, to play the role of end users A,
B and C for instance.
There are as many LT3 as required by the test configuration (LT3_1, LT3_2, .) according to the number of end
users A, B and C involved in a service scenario for instance, using different types of protocols). Pz: Contains the protocols used below the INAP between SCP and SSP, also between SSP and SRF. They could be
e.g. TCAP, SCCP and MTP of SS7 etc. Pm: Contains the protocols used below the LT3_1 between the IUT and the Signalling control point. It could be the
DSS1 protocols or ISUP SS7 protocol (in the case of having a transit exchange). Pn: Contains the used protocols below the LT3_2 between the IUT and the Signalling control point. It could be the
DSS1 protocols or ISUP SS7 protocol (in the case of having a transit exchange). 4.4 Points of control and observation (PCOs) PCO-Declarations. 1) PCO_1: This PCO is at the core INAP interface between SSP and SCP. The lower layer protocol is Pz. It could be e.g. TCAP. 2) PCO_2: This PCO is at the core INAP interface between SSP and SRF. The lower layer protocol is Pz. It could be e.g. TCAP, ISUP, B-ISUP, TUP or the NWK of DSS1. 3) PCO_3_1: This PCO is at the interface between SSP and Signalling Control A. The lower layer protocol is Pm. It could be e.g. ISUP, B-ISUP, TUP or the NWK of DSS1. 4) PCO_3_2: This PCO is at the interface between SSP and Signalling Control B. The lower layer protocol is Pn. It could be e.g. ISUP, B-ISUP, TUP or the NWK of DSS1. 4.5 Test system It is expected that the test system supports the protocols Pz, Pz-1, Pz-2 and the protocols for Pm and Pn. It is expected that the test system supports the PCO Requirements of PCO_1, PCO_2, PCO_3_1 to PCO_3_n. SIST EN 301 934-1 V1.1.1:2005

ETSI ETSI EN 301 934-1 V1.1.1 (2003-01) 11 4.6.2 Reference to product implementation The SUT can either be a Local Exchange (LE) or a Transit Exchange (TE). The exact number of testers (LT3 alone or LT3_1 and LT3_2) will depend upon the type of exchange and the configuration of the exchange, as explained by the following examples of implementation.

In this case, signalling of a call may be done either with DSS1 and ISUP (A and B involved) or only with DSS1 (A and C involved).

The transmission of INAP messages at the interface between SCF and SSF or SSF and SRF uses TCAP primitives. The LT1, LT2 communicate with the lower protocols via the SAPs with the TCAP-primitives shown in tables 2 and 3 according to clause 10 of ETS 300 374-1 [7] and ITU-T Recommendation Q.771 [8].

4.7.2 Protocol primitives at PCO_3_1 and PCO_3_2 In order to be protocol independent, a set of primitives is defined at this interface, and the next table is an example of the mapping between this generic interface and the possible signalling protocols like ISUP and DSS1.
Here follows the list of these primitives for the generic interface and a table giving the mapping of the generic primitives into real protocols. SIST EN 301 934-1 V1.1.1:2005

5 ATS naming conventions This clause describes the conventions applied to define the ATS and gives the naming conventions chosen for the different elements of the ATS. The ATS conventions are intended to give a better understanding of the ATS but they describe also the conventions made for the development of the ATS, thus for any later maintenance purposes or further development of the ATS, the conventions described in this clause shall be considered. 5.1 Declarations part This clause describes the naming conventions chosen for the elements of the ATS declarations part. 5.1.1 Test suite type and structured type definitions by reference In order to avoid misalignment problems with the base IN CS-3 standard, all the ASN.1 types used in this ATS which are defined as types in the base standard have been imported by reference to the ASN.1 types in the base standard.
Where an imported type originally contained the dash ("-") character, it is replaced by an underscore ("_") in the type as imported. 5.1.2 Test suite operations definitions The test suite operation identifiers are composed of strings in uppercase letters starting with the uppercase string "TSO_". The different strings in the definition are separated with underscores. 5.1.3 Test suite parameter declarations The test suite parameter identifiers are composed of strings starting by the uppercase string "PX_" and separated by underscores. EXAMPLE: PX_CalledPartyNumber_1 Complete names as defined in the specifications are used. SIST EN 301 934-1 V1.1.1:2005



ETSI ETSI EN 301 934-1 V1.1.1 (2003-01) 14 5.1.4 Test case selection expression definitions The naming conventions for the test case selection expression definitions use free text starting with an uppercase letter. The name of the expression is intended to explain clearly the selection rule. The test case selection expressions are generally logical combinations of the test suite parameter definitions. 5.1.5 Test suite constant declarations by reference In order to avoid misalignment problems with the base IN CS-3 standard, all the ASN.1 constants used in this ATS which are defined as constants in the base standard have been imported by reference to the ASN.1 constants in the base standard.
Where an imported constant originally contained the dash ("-") character, it is replaced by an underscore ("_") in the type as imported. 5.1.6 Test suite variable de
