Product Description

AN-FE1-4ETH Interface Converter (also as AN-FE1-4ETH Bridge) 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 AN-FE1-4ETH bridge realizes interconnection of four 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 double Ethernet interface broad band shared,  MAC address self-learning, address filtering, address table maintenance and flow control. The device has 4 ETH port, it can work like an intelligent L2 switch. It can be reduce the net node, dispense with the device as HUB, consequently reduce the malfunction node.

The AN-FE1-4ETH has the GUI NMS, it can manage the converter like an intelligent L2 switch. It can set the TAG VLAN on these 4 ETH port, can set the special tag like Q-in-Q, can configurable data rate from 32K~100M on each ETH port, can do some Qos setting.

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*64KbpsN=1~31. In the un-framing mode, the E1 channel provides a rate of 2.048Mbps and accomplishes transparent transmission.

If the AN-FE1-4ETH bridge is used in the framing mode, the transmission clock can be either provided internally, i.e. using the main clocking timing mode (INT), or extracted from the E1 channel, i.e. using slave clock timing mode.

The AN-FE1-4ETH 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.
