Thus, for a defect on a FR AC, the PE should send a BFD failure notification, but for an ATM AC defect it should insert AIS and not send a BFD failure notification. But again, we haven't specified this yet. Considering the current confusion, we should probably update OAM message mapping to cover this aspect before going to last call.
