20、e of this Recommendation is to test the signalling and procedural aspects of the stage 3 requirements as described in ITU-T Q.3617. The stage 3 description describes the requirements for several network entities. Therefore, several interfaces (reference points) are addressed to satisfy the test of t
21、he different entities. To test the appropriate entities, the configurations below are applicable. 6.1.1 Testing of the application server (AS) The AS entity is responsible for performing and managing services. The ISC interface is the appropriate access point for testing. See Figure 6-2. Rec. ITU-T
