2. Average working time without fault reaches 50, 000 hours;
3. Built-in SSRAM frame buffer;
4. Ports for Twisted wire compatible to 10Mbps and 100Mbps, easy for updating Network;
5. Ports self-adaptive to placements of Parallel and Intersection lines;
6. Built-in efficient exchange core, cache volume of 1M Bits, MAC address volume 1k, restrain broadcasting storm, flow control, CRC error examination, with functions of address filter and network segmentation;
7. Support the interconversion of 4 10Base-T and 100Base-TX Twisted Wire electric signals and 100Base-FX optical signal; with functions of port backup and multi-user insertion Optical Interface: SC/ PC, FC/ PC, ST/ PC interface ;
8. Support the transmission of data packet of max. length of 1552byte;
9. Support Qos, VOIP data packet transmission, and STP;
10. Low power consumption and heat discharge, long-time and steady operation;
