40、ture Tree and Tabular Combined Notation Upper Tester Virtual Channel Identifier Virtual Path Connection Identifier 4 4.1 Abstract Test Method (ATM) Description of ATM used The requirement for testing the network IUT is to focus on the behaviour of the network IUT at the user-network interface where

41、a TB reference point or coincident SB and TB reference point applies. Thus the IUT is the network DSS2 protocol entity 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 co

42、nsidered that 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 of the behaviour at other interfaces. An ATS based on a mul

43、ti-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 limitation here is that tests are focussed on one particular interface. Thus the test sys

44、tem is made up one Main Test Component (MTC) and one or more Parallel Test Components (PTC), see figure 1.

45、erklave 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 remote interfaces during the testing process, i.e. “how to make the IUT send the required message“. This means, in particular, that

46、the verdict will only be assigned from the protocol aspects observed on the interface under test (Le. by the “master“ tester), as it would be observed by a terminal connected to this interface. A failure in the correlation between the protocol at the different interfaces to which the different teste

47、rs 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 another interface has received the proper stimulus, the verdict will be INCONCLUSIVE. The MTC MTCA has two functions

48、 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 coordinates activities by exchanging Coordination Messages (CM) with the PTCs. Secondly it is responsible for the behaviour of the Lower Tester (L

49、T) at PCO LO. A combination of the remote and multi-party test methods is applied. As can be seen from figure 1, several PCOs are used. All PCOs reside at the service access points between layers 2 and 3.
