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.
