Abstract: PURPOSE: A communication device for an EPON(Ethernet Passive Optical Network) is provided to support uplink/downlink priority-tagged frames, and to support a VLAN(Virtual LAN) multicast in a PON bridge function, thereby constructing a VLAN in the EPON as increasing link efficiency. CONSTITUTION: A PON bridge sub layer(100) comprises as follows. A reception output processor(101) reads data from a reception output queue(105), and changes 32-bit data into an 8-bit signal to transmit the data to a switch or NP(Network Processor)(10). If an overflow is generated in a transmission input queue(106), the reception output processor(101) receives a pause signal from the transmission input queue(106), and generates a pause frame to the switch or NP(10). If the overflow is not generated in the transmission input queue(106), the reception output processor(101) reads the frame, and transmits the frame to the switch or NP(10). The reception output processor(101) performs an FCS(Frame Check Sequence) generation process for the frame only when the pause frame is generated, and sends data to an SPI processor(105).
