 Product Description: 
 GE-01 E1-RJ45 Interface Converter 
 GE-01 E1-RJ45 interface converter (commonly known as the bridge) is independently developed by the company's family of interface converter, E1 and complete conversion between 10/100BaseT Ethernet interface. The device is a high-performance, self-learning remote Ethernet bridge, completely transparent to the upper layer protocol, the user can set the bandwidth needs of arbitrary (N * 64k), rates up to 2.048Mbps. 10/100M adaptive Ethernet port, and support AUTO MDI / MDIX (automatic linear order crossover). The interface converter can automatically learn and update their associated MAC address on the LAN, and only need to forward the frame. 64M high-performance internal cache capacity from 32-512 optional. Patented to prevent the Ethernet loopback, E1 line loop to avoid causing the collapse of the Ethernet network.
