Abstract
A packet data communication system with a ring-type transmission line circulates a predetermined number of slots in which packets to be transmitted are loaded. The system includes interface nodes, provided on the ring-type transmission line, for loading packets on slots and receiving packets from slots for terminals connected thereto. In each interface node, there are a predetermined number of sub-transmission lines, for passing each of slots in parallel through the interface node, terminal interfaces each having a plurality of sending buffers for storing packets and a plurality of receiving buffers for storing packets, and a switch for connecting each of the sending buffers and receiving buffers to any one of the sub-transmission lines.
