Figure 1/ITU-T Recommendation Q.784.2 [10]: Exchange as SUT The implementation under test (IUT) is the ISUP '97 implementation in this exchange, as shown in figure 1/ITU-T Recommendation Q.784.2 [10]. The aim of the ISUP implementation is to assure capabilities and functions for circuit and signalling supervision on one hand and for call handling on the other. Circuit supervision is done mainly through the MMI (man machine interface) of the exchange. The MMI interface is implementation dependent and thus not standardized. The effects of signalling procedures of the ISDN User Part can be observed on the NNI (network-network interface), on the circuits controlled by the ISUP. The ISUP signalling protocol can be observed on the SS7 link on the NNI. The ISUP implementation will in some exchanges have to interwork with the access signalling system on the UNI (user-network interface) and involve call handling in order to establish end-to-end connec
