DATA PROCESSING METHOD IN A GPON(GIGABIT-CAPABLE PASSIVE OPTICAL NETWORK), CONCERNED WITH TRANSFERING ONT(OPTICAL NETWORK TERMINATION) MANAGEMENT CONTROL INFORMATION TO AN ONU(OPTICAL NETWORK UNIT) SUPPORTING A GEM(GPON(GIGABIT-CAPABLE PASSIVE OPTICAL NETWORK) ENCAPSULATION METHOD) MODE

摘要

PURPOSE: A data processing method in a GPON(Gigabit-capable Passive Optical Network) is provided to transfer ONT(Optical Network Termination) management control information to an ONU(Optical Network Unit) supporting a GEM(GPON(Gigabit-capable Passive Optical Network) Encapsulation Method) mode. CONSTITUTION: When a frame to be transmitted is inputted(601), the inputted frame is checked whether it is an ATM(Asynchronous Transfer Mode) frame(602). If the inputted frame is the ATM frame, it is transmitted as the ATM frame(603). If the inputted frame is not the ATM frame, the frame is determined as a GEM frame and it is checked whether the corresponding frame is a data frame(604) If the inputted frame is the data frame, the data frame is encapsulated with TDM(Time Division Multiplex) data(606) or with Ethernet data(607) depending on whether the corresponding data is transmitted in TDM mode or Ethernet mode, and then is transmitted. If the inputted frame is not the data frame, a control frame is generated and transmitted(608).
