The authors present analysis and numerical results for ATM cell transmission over a DS-CDMA satellite link. An increase in capacity is achieved by using discontinuous transmission detection (DTX) for all on-off sources, thus exploiting the burstiness of ATM traffic. Three scenarios are analysed. System performance is expressed in terms of link efficiency, capacity and their relative increases. It is shown that the bursty nature of ATM is in this case beneficial rather than detrimental to the system capacity. Finally, the idea for the connection admission control in a satellite network that conveys ATM over DS-CDMA is presented
