ETSI ETSI EN 300 196-4 V1.2.1 (2001-11) 8 4 Abstract Test Method (ATM) The remote test method is applied for the GFP user ATS. A Point of Control and Observation (PCO) resides at the service access point between layers 2 and 3. This PCO is named "L" (for Lower). The L PCO is used to control and observe the behaviour of the Implementation Under Test (IUT) and test case verdicts are assigned depending on the behaviour observed at this PCO. A second "informal" PCO, called "O" (for Operator) is used to specify control but not observation above the IUT; events at this PCO are never used to generate test case verdicts. Messages sent by the tester at this PCO explicitly indicate to the operator actions which are to be performed on the SUT. This is regarded as a preferred alternative to the use of the implicit send event. Tester Informal test co-ordination by operator SUT

Figure 1: Remote test method with PCO O for test co-ordination 5 Untestable test purposes Only clauses 6.2.2 and 6.2.3.2.3.2.5 of EN 300 196-3 [3] contains testable test purposes. All other test purposes are too generic and parameterized. These test purposes rather provide a general example for the behaviour that should be tested in the ATSs for supplementary services which use the generic functional protocol. Some of the tests contained in clause 6.2.2 of EN 300 196-3 [3] are also untestable due to the fact that the call state in which the test should be performed is unstable. These are: GFP_U7_01_003, GFP_U7_02_003, GFP_U7_03_003, GFP_U7_04_003, GFP_U7_05_003, GFP_U7_07_017, GFP_U7_07_022, GFP_U7_09_017, GFP_U7_09_021. GFP_U7_09_021. SIST EN 300 196-4 V1.2.1:2004



ETSI ETSI EN 300 196-4 V1.2.1 (2001-11) 9 6 ATS conventions 6.1 Version of TTCN used The version of TTCN used is that defined in ISO/IEC 9646-3 [7]. 6.2 Use of ASN.1 6.2.1 Situations where ASN.1 is used ASN.1 has been used for three major reasons. First, types defined in ASN.1 can model problems that "pure" TTCN cannot. For instance, data structures modelling ordered or unordered sequences of data are preferably defined in ASN.1. Second, ASN.1 provides a better restriction mechanism for type definitions by using sub-type definitions. Third, it is necessary to use ASN.1 to reproduce the type definitions for remote operation components as specified in the base standards. 6.2.2 Specification of encoding rules There is a variation in the encoding rules applied to ASN.1 types and constraints specified in this ATS and therefore a mechanism is needed to differentiate the encoding rules. However the mechanism specified in ISO/IEC 9646-3 [7] does not facilitate definition of the encoding rules as needed for this ATS. A solution is therefore used which is broadly in the spirit of ISO/IEC 9646-3 [7] in which comment fields have been used as a means of encoding rules. For ASN.1 used in this ATS, two variations of encoding rules are used. One is the commonly known Basic Encoding Rules (BER) as specified in ITU-T Recommendation X.209 [12] and ITU-T Recommendation X.690 [11]. In the second case the encoding is according to ISDN, i.e. the ASN.1 data types are a representation of structures contained within the ISDN specification (basic call, Generic functional protocol or individual supplementary service). For example, if octets of an information element are specified in ASN.1 as a SEQUENCE then this should be encoded in an Executable Test Suite (ExTS) as any other ISDN information element specified using tabular TTCN. This ISDN encoding variation is the default encoding rule for this ATS. This means that all ASN.1 constraint tables are encoded using ISDN (non-BER) encoding unless stated otherwise. BER encoding should never be applied to an ASN.1 constraint where BER encoding has not been specified. For BER encoding, an indication is given in the comments field of the table header. For this ATS such indications appear in the ASN.1 type definitions tables only. In the table header comment field, the notation "ASN1_Encoding: BER" is used. BER coding according to ITU-T Recommendation X.690 [11]. shall be used for any type with this notation. Note that within BER, there are a number of variations for the encoding of lengths of fields. According to EN 300 196-1 [1], an IUT should be able to interpret all length forms within BER for received PDUs. When sending PDUs containing BER encoding, EN 300 196-1 [1] gives guidelines but makes no restrictions on the length forms within BER which an IUT may apply.

Thus there is a straightforward one-to-one mapping. 8 PCTR conformance A test laboratory, when requested by a client to produce a PCTR, is required, as specified in ISO/IEC 9646-5 [9], to produce a PCTR conformant with the PCTR template given in annex B of ISO/IEC 9646-5 [9]. Furthermore, a test laboratory, offering testing for the ATS specification contained in annex C, when requested by a client to produce a PCTR, is required to produce a PCTR conformant with the PCTR proforma contained in annex A of the present document. A PCTR which conforms to this PCTR proforma specification shall preserve the content and ordering of the clauses contained in annex A. Clause A.6 of the PCTR may contain additional columns. If included, these shall be placed to the right of the existing columns. Text in italics may be retained by the test laboratory. 9 PIXIT conformance A test realizer, producing an executable test suite for the ATS specification contained in annex C, is required, as specified in ISO/IEC 9646-4 [8], to produce an augmented partial PIXIT proforma conformant with this partial PIXIT proforma specification. An augmented partial PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a minimum, have contents which are technically equivalent to annex B. The augmented partial PIXIT proforma may contain additional questions that need to be answered in order to prepare the Means Of Testing (MOT) for a particular IUT. A test laboratory, offering testing for the ATS specification contained in annex C, is required, as specified in ISO/IEC 9646-5 [9], to further augment the augmented partial PIXIT proforma to produce a PIXIT proforma conformant with this partial PIXIT proforma specification. A PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a minimum, have contents which are technically equivalent to annex B. The PIXIT proforma may contain additional questions that need to be answered in order to prepare the test laboratory for a particular IUT. 10 ATS conformance The test realizer, producing MOT and ExTS for this ATS specification, shall comply with the requirements of ISO/IEC 9646-4 [8]. In particular, these concern the realization of an ExTS based on each ATS. The test realizer shall provide a statement of conformance of the MOT to this ATS specification. An ExTS which conforms to this ATS specification shall contain test groups and test cases which are technically equivalent to those contained in the ATS in annex C. All sequences of test events comprising an abstract test case shall be capable of being realized in the executable test case. Any further checking which the test system might be capable of performing is outside the scope of this ATS specification and shall not contribute to the verdict assignment for each test case. Test laboratories running conformance test services using this ATS shall comply with ISO/IEC 9646-5 [9]. A test laboratory which claims to conform to this ATS specification shall use an MOT which conforms to this ATS. SIST EN 300 196-4 V1.2.1:2004



ETSI ETSI EN 300 196-4 V1.2.1 (2001-11) 11 11 Configurations required in testing Some test cases require the IUT to be configured in special ways. These test cases and the special configurations are indicated in table 2 below. Except where indicated otherwise these special configurations should not be used for other test cases. Table 2: Special configurations Configuration PIXIT reference Test Suite Parameter Test cases Hold not permitted (as a responding entity) 2.3 PX_HOLD_NOT GFP_U7_07_24 - 29 Retrieve not permitted (as a responding entity) 2.4 PX_RET_NOT GFP_U7_09_35 - 40 NCICS connections rejected (see note) 2.8 PX_REJECT_NCICS GFP_U8_09_009 NOTE: If rejection of a NCICS connection can be provoked by use of a Called party number not matching the IUT no special configuration is necessary for this test case.
NOTE: Certain items in the GFP PICS (EN 300 196-2 [2]) assume that the ability of an implementation to act as a initiating or as a responding entity is a global characteristic. When this assumption is incorrect and the IUT can act as an initiating entity for the HOLD/RETRIEVE procedures and a responding entity for some other part of GFP, some test cases in the GFP_U07_03, GFP_U07_04, GFP_U07_07 and GFP_U07_09 groups can be selected that are not applicable to the IUT. Users of this ATS are therefore recommended to check that TPs in these groups are only selected if the behaviour being tested is actually supported by the IUT. SIST EN 300 196-4 V1.2.1:2004
