Provide externally four Ethernet interfaces (LAN interface); provide internally eight Ethernet data interfaces with FE full duplex mode (WAN interface);
This card can work in four modes: 10Mbit/s half duplex, 10Mbit/s full duplex, 100Mbit/s half duplex and 100Mbit/s full duplex. Specific work status is accomplished through auto-negotiation and users can switch work status according to demand;
Support three encapsulation modes: (GFP, LAPS and HDLC); cross-connect particle is VC-12;
Support back-pressure flow control in half duplex mode;
Support IEEE 802.3x flow control in full duplex mode;
Support VLAN segmentation based on IEEE802.1Q and port;
Support bandwidth limit and QoS function;
Accomplish port trunking;
Support remote download function of BCT and FPGA software;
Support IGMP multicast protocol; can decrease network flow effectively in the case of multimedia transmission.
