Abstract
A router device has a plurality of ingress line interface cards (LICs), a plurality of egress LIC's, a backplane and a controller. Transmission of signals from the ingress LICs to the controller, and from the controller to each of the ingress and egress LICs takes place across the backplane. Each ingress LIC is provided with a dedicated timeslot in which it can send information to the controller via connection. Information is sent in a slice within the dedicated timeslot and each egress LIC ignores data sent by a given ingress LIC within the timeslot assigned to said ingress LIC. A similar system is used for transmission of communications from the controller to the LICs. It is thus possible to avoid provision of additional, dedicated communications paths between the LICs (ingress and egress) and the controller.
