A heterogeneous traffic Connection Admission Control system in Asynchronous Transfer Mode (ATM) networks and a method therefor, dynamically controls a system capacity to a delay demand bound of a heterogeneous traffic class in order to meet a cell loss rate for an user's demand, reduce the influence of mutual traffic interferences and enable the Connection Admission Control in a real time, in a manner that an equivalent band width of each traffic class is calculated using a distribution function of the number of cell estimated through the traffic measurement of each of class, a capacity of a transferring channel is determined in proportion to the equivalent bandwidth calculated upon the connection request of a new call; and the link capacity determined above is compared with the results of the maximum cell rate of the call requesting the new call plus the equivalent bandwidth of all classes.
