20、gnalling and procedural aspects of the stage 3 requirements as described in TS 183 054 1. The stage 3 description describes the requirements for several network entities and also the requirements regarding terminal devices. Therefore several interfaces (reference points) are addressed to satisfy the

21、 test of the different entities. Therefore to test the appropriate entities the configurations below are applicable: 4.1.1 Testing of the AS The AS entity is responsible for performing and managing services. The ISC interface is the appropriate access point for testing. Figure 2: Applicable interfac

22、e to test AS functionalities If the ISC interface is not accessible it is also possible to perform the test of the AS using any NNI (Mw, Mg, Mx) interface (see figure 3). In case only the Gm interface is accessible this interface can be used instead for testing, but the verification of all requireme

Additional references are added to identify the actual test suite and whether it applies to the network or the user (see table 1). Tabl

In the relevant test purposes the CUG index of this second closed user group is referred to as “preferred CUGIndex“. In clause 5.2.2.7 the originating user has not subscribed to the CUG service.
