Overview
     MEL-200F is a high performance and self-learning long distance Ethernet bridge that could point-to-point transfer data from E1 channels to Rj-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 RJ45 interfaces are provided at the end of Ethernet LAN to accomplish various functions including double Ethernet interface broad band shared, MAC address self-learning, address filtering, address table maintenance and flow control. For the client which only require not more than 2 Ethernet, it can be reduce the net node, dispense with the device as HUB, consequently reduce the malfunction node.
