    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 {[}RFC3985{]} to realize an end-to-end emulated Ethernet service. This document augments the mapping of defect states between a PW and associated AC of the end-to-end emulated service in {[}PW-OAM-MSG- MAP{]}. In {[}PW-OAM-MSG-MAP{]}, Ethernet OAM was not covered due to lack of Ethernet OAM maturity. However, since then, {[}Y.1731{]} and {[}802.1ag{]} have been completed, and this document specifies the mapping of defect states between Ethernet ACs and corresponding Ethernet PWs.},
