Abstract
Line cards provide an input/output interface between synchronous communication channels and an asynchronous network. An input line card generates a plurality of packets where each packet contains information carried by a group of synchronous communication channels; each synchronous communication channel of the group having a destination of the same output line card. A mechanism is provided for selecting a sequence for the sequential transmission of packets from the input line cards to the asynchronous network. The selecting mechanism minimizes the probability that a plurality of the input line cards will concurrently transmit a packet to the same output line card thereby creating a collision of packets requiring that all but one of the colliding packets be stored in a queue. Thus, minimizing collisions also minimizes queuing delays.
