Optical line termination in ATM-based PON
An optical line termination in an asynchronous transmission mode includes a downstream frame processing unit for receiving and churning an asynchronous mode cell to generate a downstream frame, and converting a parallel data of the downstream frame into a serial data thereof, a wavelength division multiplexing unit for performing an electro/optical conversion of the serial data of the downstream frame and performing a wavelength division multiplexing thereof, an upstream frame processing unit for extracting data from the wavelength division multiplexing unit, searching an overhead field, delineating a slot boundary, and processing a PLOAM cell and a divided slot separately, a control signal generation unit for performing a MAC protocol and generating variables and timing signals used for the downstream frame processing unit and the upstream frame processing unit, and a control unit for controlling the downstream frame processing unit and the upstream frame processing unit by using the variables and the timing signals from the control signal generation unit.
