Framed E1 Interface Converter is an Ethernet bridge of high performance, which accomplishes the converting between the 100M Ethernet port and the E1 port. As an extended device of the Ethernet, the FE1 to Ethernet Bridge realizes interconnection of two Ethernet by using the E1 channel provided by existing networks with low cost.
100BASE-TX (RJ45) interfaces are provided at the end of Ethernet LAN to accomplish various functions including MAC address self-learning, address filtering, address table maintenance and flow control.
E1 interfaces conforming to ITU-T G.703 and G.704 proposals are provided at the end of WAN, supporting RJ45 and BNC connection modes. The E1 ports support both framing and un-framing architecture. The user can select an operating mode for the E1 interface according to the connected E1 environment. This provides flexibility of network application. In the framing mode, the E1 interface provides a rate of N*64Kbps(N=1~31). In the un-framing mode, the E1 channel provides a rate of 2.048Mbps and accomplishes transparent transmission.
The FE1 to Ethernet Bridge provides plenty of self-test functions, supporting local loop and remote loop. It also provides pseudo random code test function to test error codes in the circuit.
