Framed E1-4FE Interface Converter

    E1-4ETH interface converter is based on FPGA. The device provides the transition between ITU-T G.703 (E1) standard framed E1 interface and 10/100Base-T interface. It is a high-capability, self-adaptable long-distance Ethernet bridge. The product is small and low-cost. It is widely used in connecting between WAN and LAN, monitoring, etc.

● Based on self-copyright IC
●E1 supports any timeslot set, the rate is 64K-2048K

●Can realize monitor and control of remote equipment, OAM management data did not  take up the user’s  timeslot and save E1 bandwidth

●Have the function of E1 interface loopback check, avoid the converter crashing because of interface loop  return; Have an indicator  when the device is power-off or

●E1 line is broken or loses signal;

●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 (1916 Bytes);

●4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;

●Ethernet interface supports10M/100M, half/full duplex auto-Negotiation, and AUTO-MDIX(crossed line and  straightly connected line self-adaptable );

●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)

●Have the Ethernet monitor self-reset function, the equipment will not dead

●Ethernet interface supports the counters of receiving and transmitting frame, receives wrong frame counters.E1 interface supports the counters of receiving the wrong frame;

●Realize monitor of remote equipment temperature and voltage from local equipment;

● 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;
