Abstract
A system and method are provided for tolerating data line faults in a packet communications network. The method comprises: serially transmitting information packets from at least one traffic manager (TM); at a switch fabric, accepting information packets at a plurality of ingress ports, the information packets addressing destination port card egress ports; selectively connecting port card ingress ports to port card egress ports; serially supplying information packets from a plurality of port card egress ports; sensing a connection fault between the switch fabric and the TM; and, in response to sensing the fault, reselecting connections between the switch fabric port card ports and the TM. Some aspects comprise: an ingress memory subsystem (iMS) receiving cells on an ingress port exceeding an error threshold. Then, reselecting connections between the port card ports and the TM includes the iMS sending a message to the iTM identifying the faulty ingress connection.
