Line cards provide an input/output interface between synchronous communication channels and an asynchronous network. The input line card translates information received from the synchronous communication channels into packets for transmission to the asynchronous network. Each line card generates and stores packets corresponding to a time frame associated with the synchronous communication channels, A sequence is selected for the sequential transmission of packets by each input line card to the asynchronous network. The cumulative number of packet collisions that would occur at each output line card during the predetermined time frame is determined. If the cumulative number of collisions exceeds a predetermined delay threshold, the number of packets actually transmitted to the system is reduced preferably by denying service to new call origination requests. This technique keeps the maximum cumulative collisions for each output line card within the predetermined delay threshold.
