     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.
