     Abstract 

        This document specifies the mapping of defect states between 
        Ethernet Attachment Circuits (ACs) and associated Ethernet 
        Pseudowires (PWs) connected in accordance to the PWE3    
        architecture to realize an end-to-end emulated Ethernet service. 
        It standardizes the behavior of Provider Edges (PEs) with 
        respect to Ethernet PW and AC defects.
