E1-4FE Interface Converter

This interface converter is based on FPGA. It can realize 4 channels of Ethernet data transmission over 1E1 circuits,  providing users with Ethernet access at the rate of 1984K. It is widely used in finance, securities, and security departments which need to be provided with two different networks, and both on a physical network can be completely separated. For example, the financial system business network, internal office network, and business network can’t be linked together. This interface multiplexer can solve this problem.

● Based on self-copyright IC
● Can realize 4 channels Ethernet data transmission by 1 E1 circuit
● Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
● 4Channel Ethernet rate is 1984Kbps, set up the first, second, third channel rate, the fourth channel Ethernet rate automatic allocation
● The local device can force the remote device rate to follow it
● Have the function of E1 interface loopback check, to avoid the converter crashing because of interface loop return;
● Can set the E1 line not to send the LINK signal to the Ethernet interface while the E1 line is broken;
● The Ethernet interface supports jumbo frames (2036 Bytes)
● Ethernet interface supports10M/100M, half/full duplex auto-Negotiation, and AUTO-MDIX  (crossed line and straightly connected line self-adaptable )
● Have the Ethernet monitor self-reset function, the equipment will not dead
● Provide 2 clock types: E1 master clock and E1 line clock;
● Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM)
● Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
● Realize monitor of remote equipment temperature and voltage from local equipment;
● Support SNMP Network Management;
