ETSIEN 300 058-6 V1.2.4 (1998-06)84Abstract Test Method (ATM)4.1Description of ATM usedThe requirement for testing the network IUT is to focus on the behaviour of the network IUT at the user-network interfacewhere a T reference point or coincident S and T reference point applies. Thus the IUT is the network DSS1 protocolentity at a particular user-network interface and is not the whole network.It is possible to specify an ATS based on a Single party (remote) test method for such an IUT. However, it is consideredthat an ATS based on such an approach is of limited use as the only way to specify IUT generated PDUs is to use the"implicit send" statement. Many users of such an ATS would replace the "implicit send" statements with descriptions ofthe behaviour at other interfaces.An ATS based on a multi-party test method is considered to be more useful in that it is closer to how a real test suitewould be constructed. Such a test method specifies behaviour at multiple network interfaces. One very importantlimitation here is that tests are focused on one particular interface. Thus the test system is made up one Main TestComponent (MTC) and one or more Parallel Test Components (PTC), see figure 1.4.1.1Conventions for test components and PCOsMaster partSlave partMTCAPTC1CPA1L0 PCOL1 PCOIUTNETWORKFigure 1: Multi-party test methodSIST EN 300 058-6 V1.2.4:2003



ETSIEN 300 058-6 V1.2.4 (1998-06)9In a master/slave arrangement, the MTC is considered to be the master while the PTCs are the slaves. The "slave" testersare only an explicit description of how to deal with the "other" interfaces during the testing process, i.e. "how to make theIUT send the required message".This means, in particular, that the verdict will only be assigned from the protocol aspects observed on the interface undertest (i.e. by the "master" tester), as it would be observed by a terminal connected to this interface. A failure in thecorrelation between the protocol at the different interfaces to which the different testers are connected, i.e. in themechanism of the functional service itself, will not cause a FAIL verdict. For instance, if the IUT fails to send a messageon the tested interface after another interface has received the proper stimulus, the verdict will be INCONCLUSIVE.The MTC MTCA has two functions in this configuration. Firstly, it has the MTC function of controlling the one or morePTCs. Thus it is responsible for starting the PTCs and afterwards co-ordinates activities by exchanging Co-ordinationMessages (CM) with the PTCs. Secondly it is responsible for the behaviour of the Lower Tester (LT) at PCO L0.A combination of the remote and multi-party test methods is applied. As can be seen from figure 1, several PCOs areused. All PCOs reside at the service access points between layers 2 and 3.MTCSUTPTC1Layer 3¾¾¾¾Layer 2¾¾¾¾Layer 1¾L0¾¾¾¾¾¾¾¾¾IUT¾¾¾¾¾¾¾¾¾

PCO L0 is used to control and observe the behaviour of the IUT and testcase verdicts are assigned depending on the behaviour observed at this PCO. The PTC PTC1 uses PCO L1. This PCO isused to control and, in a limited way, observe the behaviour of the network equipment at interfaces other than the oneunder test. No verdicts are assigned at this PCO.As stated in a previous paragraph, the non-receipt of network generated messages at L0, which are stimulated by events atthe L1, will result in INCONCLUSIVE rather than FAIL verdicts being assigned.4.1.2Conventions for variables and parametersMTCAcall referenceCREF1B channel (basic)bch_num1(to PTC1)channel nr (primary)CH_NUM1PCO L0IPN0, LIPN0PTC1call referenceP1CREFB channel (basic)P1_bch_numchannel nr (primary)P1_CH_NUMPCO L1IPN1, LIPN1SIST EN 300 058-6 V1.2.4:2003



ETSIEN 300 058-6 V1.2.4 (1998-06)104.2Alternative ATMAs stated in subclause 4.1, an ATS based on a single-party (remote) ATM is possible. Such an ATS may be generatedfrom the one specified in the present document. The following general steps should be taken:1)remove all PTC behaviour;2)remove all CREATE statements;3)replace CMs which are used to provoke PDUs at the MTC, with implicit send statements.An example, showing the difference between the multi-party ATM and single-party ATM for a single test case, is given intables 1 and 2.Table 1: Test case dynamic behaviour table using multi-party ATMTEST CASE DYNAMIC BEHAVIOURTest Case NameHOLD_N04_001GroupRemoteUser_ST_OR_T/Holding/PurposeEnsure that the IUT, while in the Active call state N10, tonotify the non-served user that the call is heldsends a NOTIFY message with a notification indicator coded as"remote hold" to user B and remains in the Active call state.DefaultDF69901(1)ConfigurationCONFIG1Comments9.2.1validoptional Nr| Label| BEHAVIOUR DESCRIPTION| CREF| V| COMMENTS1||CREATE ( PTC1: PTC1_IN_servedUser)|||2|| +PR31002|||preamble N103||
