Summary:PURPOSE: An ethernet physical layer protocol (PHY) extending method and an apparatus for the same are provided to increase advantages of an ethernet PHY in cables causing interference between symbols such as bridged tap telephony wiring. CONSTITUTION: A preamble synchronization logic (208) is synchronized with a preamble frame of an ethernet signal received from a receiver in a channel. The preamble frame includes preamble codes. The preamble frame is adjacent to an idle signal frame of the ethernet signal. A preamble generator (210) copies the preamble codes. A decision feedback equalizer (DFE) (212) performs training based on copied preamble codes.
