1. DESCRIPTION
4E1/10/100Base-T Bridge adopts the patent 2M technique of reducing dithering, figure lock and anti-interfere. It’s a system of multi-operational light lines with the core of FPGA, which is suitable for the situations of the high request reliability and assistant function. Ethernet data can be transferred in several E1 lines, so 4E1/10/100Base-T Bridge can be use to build a broadband Ethernet. 4E1/10/100Base-T Bridge offers 4*E1 interface up to bandwidth 8Mbps. The equipment allow the mistake such as some E1 passways is down, the equipment does not abort data transmitting and just reduce the throughput.
