Abstract
The present invention relates to an Ethernet Passive Optical Network (EPON), which provides high-speed data communication services and voice services over the EPON, thus integrating subscriber access networks into a single access network. In the network system of the present invention, with respect to upstream data connected to a subscriber, codes analog signals into digital signals and convert digital signals into packets in the form of Ethernet frames, converts TDM data into Ethernet frames, attaches the MAC address of a TDM port at the end of an optical cable to the Ethernet frames and then transmits the Ethernet frames to the EPON, switches received data depending on Ethernet MAC addresses, converts TDM data and interfaces the converted TDM data with the local exchange.
