22、cribed in ETSI TS 124 605 1. The stage 3 description respects the requirements to several network entities and also to requirements regarding to end devices. Therefore several interfaces (reference points) are addressed to satisfy the test of the different entities. 4.2.1 Testing of the AS The AS en
23、tity is responsible for performing and managing services. The ISC interface is the appropriate access point for testing. Figure 4.2-1: Applicable interface 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) i
24、nterface (see figure 4.2-2). In case only the Gm interface is accessible this interface can be used instead for testing, but the verification of all requirements may not be possible.
