802.3ahAn IEEE standard in development for Ethernet in the First Mile (EFM). It is designed to extend Ethernet from the carrier to the customer over copper or fiber lines. EFMC (EFM over Copper) is expected to be based on SHDSL, and EFMF (EFM over Fiber) is expected to be based on EPON (Ethernet PON). The EFM group decided to call the "last mile" the "first mile." Of course!
