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 with low cost. It is widely used in connecting between WAN and LAN, monitoring, etc


uBased on self -copyright  IC 

uE1 supports any timeslot set, the rate is 64K-2048K

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

u Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop  return;

u Have indicator  when the device is power-off or E1 line is broken or lose signal;

uCan set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken;

u The Ethernet interface supports jumbo frames (1916 Bytes);

u4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;

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

uProvide 2 clock types: E1 master clock and E1 line clock;

u Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM)

uHave pseudo random code test function, easy the installation and maintenance;

u Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;

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

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

uRealize monitor of remote equipment temperature and voltage from local equipment;

u Support SNMP Network Management;

u Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber    Modem (C)
