40、lementation under test The System Under Test (SUT) is an exchange. The Implementation Under Test (IUT) is the ISUP v3 implementation in this exchange, mainly the part responsible for the Application Transport Mechanism, support of VPN applications with PSS1 information flows, as shown in figure 1. T
41、he protocol functions for the Application Transport Mechanism, support of VPN applications with PSS 1 information flows relates to the signalling associations with a bearer (ISUP). Therefore the defined ISUP Basic Call and its associated formats and codes are required to support the Application Tran
42、sport Mechanism for VPN applications. The following main subjects have to be considered in this area: a) APM-user Protocol Control (APM-user Application Service Element); b) Application Transport Mechanism protocol control (APM Application Service Element); c) ISUP Basic Call (ISUP Application Servi

45、ation is the distributed multi-party test method. The ATM is defined at an appropriate level of abstraction so that the test cases may be specified appropriately, without adding restrictions to the implementation under test. The testing architectures are described in the following subclauses. The AT
46、S is written in concurrent TTCN. Local exchanges As mentioned above, the IUT can be tested within different configurations. The following text describes the test configuration for the IUT where the software for IUSP v3 and also the VPN part reside in a local exchange. Figure 2 shows the logical test
47、 components of the adopted test configuration. The main test component is located on the right side of the IUT, it contains the ISUP part. On the left side there is a parallel test component which covers the VPN part. To observe and control the message flow on the ISUP and VPN side for each side a P
48、oint of Control and Observation (PCO) is needed. The PCO for the ISUP link is abbreviated with an L followed by two letters indicating the interface. The PCO for the PSS 1 interface is abbreviated with an A followed by two letters indicating the interface. The LAB PCO is used by the Lower Tester (LT
49、) to control and observe the ISUP on the signalling to the exchange. The ACH PCO is used by the Upper Tester (UT) to control and observe the PSS 1 signalling to the PIN. The MNT PCO is used by the Upper Tester (UT) to control and observe the maintenance functions of the exchange. ETSI 10 This configuration to test the local exchanges is presented in figure 2.
