Embodiment Construction
[0027] The present invention builds an embedded PowerPc CPU subsystem based on the PowerPc405 (referred to as PPC) hard core embedded in the XILINX V4 FX100 FPGA as the core. After the subsystem is powered on and completes boot (boot), it first initializes the system with the support of the operating system and software, completes the configuration and setting of the GPON OLT MAC, and completes the optical terminal side hardware logic module (OLT) The network unit (ONU) performs related configuration and initialization (including assisting in ranging, assisting in obtaining the S / N of the ONU, and setting the power of the ONU, etc.). After the system enters normal operation, it monitors the working status of OLT and ONU, assists in the processing of alarms and errors of OLT and ONU, and assists the hardware in the bandwidth allocation of the DBA algorithm of TCONT (Transmission Container) in the ONU. In addition, the PPC system also assists the OLT to complete the key exchange...
