4 Abstract Test Method (ATM)
4.1 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 a T reference point or coincident S and T reference point applies. Thus the IUT is the network DSS1 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 considered
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 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
limitation 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.

Figure 1: Multi-party test method
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 during 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 interface. 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 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 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 L0.
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.

Figure 2: Combination of the remote and multi-party test methods
The MTC PCO is named "L0" ("L" for Lower). PCO L0 is used to control and observe the behaviour of the IUT and test
case verdicts are assigned depending on the behaviour observed at this PCO. The PTC PTC1 uses PCO L1. This PCO is
used to control and, in a limited way, observe the behaviour of the network equipment at interfaces other than the one
under 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 at
the L1, will result in INCONCLUSIVE rather than FAIL verdicts being assigned.

4.2 Alternative ATM
As stated in subclause 4.1, an ATS based on a single-party (remote) ATM is possible. Such an ATS may be generated
from 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 in
tables 1 and 2.
Table 1: Test case dynamic behaviour table using multi-party ATM
TEST CASE DYNAMIC BEHAVIOUR
Test Case Name HOLD_N04_001
Group RemoteUser_ST_OR_T/Holding/
Purpose Ensure that the IUT, while in the Active call state N10, to
notify the non-served user that the call is held
sends a NOTIFY message with a notification indicator coded as
"remote hold" to user B and remains in the Active call state.
