42、UT is to focus on the behaviour of the network IUT at the user-network interface where a T reference point or coincident S and T reference point applies. Thus the IUT is the network DSSI protocol entity at a particular user-network interface and is not the whole network. It is possible to specify an
43、 ATS based on a Single party (remote) test method for such an IUT. However, it is considered that an ATS based on such an approach is of limited use as the only way to speciQ IUT generated PDUs is to use the “implicit send“ statement. Many users of such an ATS would replace the “implicit send“ state
44、ments with descriptions of the 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 suite would be constructed. Such a test method specifies behaviour at multiple network interfaces. One very important limita
45、tion here is that tests are focused on one particular interface. Thus the test system is made up one Main Test Component (MTC) and one or more Parallel Test Components (PTC), see figure 1. 4.1 .I Conventions for test components and PCOs Master pari Slave pari I I L1 pco Figure I: Multi-party test me
46、thod ETSI STDmETSI EN 300 052-b-ENGL 1999 3400855 04b1794 507 9 ETSI EN 300 052-6 V1.3.3 (1999-11) In a master/slave arrangement, the MTC is considered to be the master while the PTCs are the slaves. The “slave“ testers are only an explicit description of how to deal with the “other“ interfaces duri
47、ng the testing process, i.e. “how to make the IUT send the required message“. This means, in particular, that the verdict will only be assigned from the protocol aspects observed on the interface under test (i.e. by the “master“ tester), as it would be observed by a terminal connected to this interf
48、ace. A failure in the correlation between the protocol at the different interfaces to which the different testers are connected, i.e. in the mechanism of the functional service itself, will not cause a FAIL verdict. For instance, if the IUT fails to send a message on the tested interface after anoth
49、er 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 more PTCs. Thus it is responsible for starting the PTCs and afterwards Co-ordinates activities by exchanging Co-ordination Messages (CM) with the PTCs. Secondly it is responsible for the behaviour of the Lower Tester (LT) at PCO LO. A combination of the remote and multi-party test methods is applied. As can be
