In this paper, we focus on an integrated voice and data system over a CDMA Unslotted ALOHA and investigate the effect of transmission control for data traffic. We consider Channel Load Sensing Protcol (CLSP) as a transmission control protocol and investigate the effect of the thresholds, which may differ due to the requirement of each medium. As a result, we find that the threshold assigned for data is very effective to improve both performances of the throughput for data and the Erlang capacity for voice users, and also, to correspond to the priority for both media. Consequently, we obtain an optimum threshold for data to make the best use of the total channel capacity.
