ABSTRACT:
System and method for handling miscabling defects in a node in a resilient packet ring (“RPR”) network are described. In one embodiment, the method comprises detecting a miscabling defect at the node; setting a state of a miscabling parameter to true in a protection state machine of the node; and responsive to the setting, notifying a neighboring node of a signal failure (“SF”).
