Overview
MEO-401 is a high performance and self-learning long distance Ethernet bridge that could point-to-point transfer data from 1-4E1 channels to 1-4Rj-45 interfaces. It is compact in size and low in cost and suitable to cost effective bridging application. It could be used as an extension or divider to LANs with bit rate base structure. This equipment could continuously learn the MAC addresses among the connected LANs and decide to transmit or filter. It has a table containing up to 10,000 addresses and it could be automatically updated. The filtering and transmitting rate is up to 20,000 frames, and the buffer could contain 256 frames, the transfer delay is 1 frame. When used as a LAN extension or divider, it works under the modes either filtering or filtering prohibited. China has an extensive resource in E1 channels and so this product is widely used in network connection.
