V-rebplus is a 10/100m, self-adaptive, high performance, self-learning, remote ethernet bridge. Its low cost make it suitable for cost-sensitive bridging application or as a lan extender or subsection. When it is used as a extender or subsection, it can forbid filtrating to let all of the amount of traffic are transmitted in wan. Its 10 base-t interface can run in full duplex ethernet with topology and improve data throughput by eliminating the padding bit in 64 bytes frame. Variable speed up to 10mbps on the wan line is supported transparently. The line rate may be adjusted in running without any influence to v-rebplus. V-reb plus does not perform any negotiation over the link, which is specially suitable for satellites and other wireless broadcast applications. Features: *10/100m high fast powered self-adapting self-educated long-range ethernet bridge. * lan according with: ieee802.3/ieee802.3u/ethernet interface: utp(rj45) * wan interface: v.24/rs232 & v.35 optional * wan line speed rate reaches up to 10mbps. * speed of filtrating and transmitting is up to 30000 frame/ second. Buffer is 16m. * it can store up to10000 mac. And mac addresses have functions of automatically learning and updating. * ethernet utp interface has function of vlan802.1q. There have two transmitting mode to choose: data and image. * automatically learn mac addresses on the lan to which it is connected, and forward only those frames destined for another lan. Carton.
