Abstract
A system and method are provided for tolerating data line faults in a packet communications switch fabric. The method comprises: accepting information packets including a plurality of cells, at a plurality of ingress port card ports, the plurality of information packets addressing a plurality of egress port card ports; selectively connecting port card ports to port card backplane data links; selectively connecting port card backplane data links and crossbars; sensing a connection fault in a backplane data link; in response to sensing the fault, reselecting connections between the port card ports and the port card backplane data links; in response to reselecting connections between the port card ports and the port card backplane data links, serially transferring packets through the port cards; serially transferring packets through the crossbars to the egress port cards; and, suspending use of the faulty connection.
