Twomethods are applied; the Remote test method, and the Multi-Party test method.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.SIST EN 301 061-4 V1.1.4:2005



ETSIETSI EN 301 061-4 V1.1.4 (1999-10)94.1.1Functional subsetsThe Generic Function Protocol is divided into a number of entities as shown in figure 1. This ATS is principallyconcerned with the testing of the Protocol Control and Generic Functional Transport Control entities, Coordinationfunctions and ROSE entities.NOTE:Valid behaviour of the application layer is supplementary service specific and its testing is specified intest specifications for individual supplementary services (if any). DSE requirements are excluded from thescope of the present document.The testing of all these layers is performed using a PCO at the SCM/Network layer boundary.SSControlGeneric FunctionalCoordinationProtocol ControlLayer 2Layer 1 FunctionNetworkTransport ControlApplicationLayerGFPROSEDSELayerSCMACSENOTE:Grey shading indicates entities not part of the GenericFunctional Protocol.Figure 1: GFP functional subsets4.1.2PINX role and Test Component Configuration considerationsA PINX may act either in the role of an End PINX or in the role of a Transit PINX. A particular PINX may be capableof acting in one or both roles. Whereas the Generic Functional Transport Control (GFTC) requirements generallydepend 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 thepre-condition in some TPs concerned with PC requirements. For these cases, which will require different test componentconfigurations, there may be two separate Test Cases (TCs), one for each role, generated from each relevant TP.The different configurations used are depending on the role of the PINX, in the sense that the slave part will use adifferent access point to the public network.4.1.2.1Single PCO testingSingle PCO testing is used for the tests when events at the outgoing side are not required to be tested and when noactivity is expected at the outgoing side, i.e. only one interface is reacting.CONFIG_MONO: this configuration is mainly used for NCICS connection.4.1.2.2Multi PCO testingMulti PCO testing is used for the tests when events at the outgoing side are required either to be tested or to provoke areaction of the IUT at the tested interface. the configuration defined i depending on the role of the PINX at the testedinterface.CONFIG_DUAL: The remote access for this configuration is directly dependant on the role of the PINX, transit or end.SIST EN 301 061-4 V1.1.4:2005

The "slave" testersare only an explicit description of how to deal with the "other" interfaces during the testing process, i.e. "how to makethe IUT send the required message".This means, in particular, that the verdict will only be assigned from the protocol aspects observed on the interfaceunder test (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 coordinates activities by exchanging CoordinationMessages (CM) with the PTCs. Secondly it is responsible for the behaviour of the Lower Tester (LT) at PCO L0.SIST EN 301 061-4 V1.1.4:2005
