Name:Framed E1-4FE Converter

Product Description


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.


ØBased on self -copyright  IC 
ØE1 supports any timeslot set, the rate is 64K-2048K
ØCan realize monitor and control of remote equipment, OAM management data did not  take up user's  timeslot and save E1 bandwidth
ØHave the function of E1 interface loop back check, avoid the converter crashed because of interface loop  return;
ØHave indicator  when the device is power-off or E1 line is broken or lose signal;
ØCan set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken;
ØThe Ethernet interface supports jumbo frames (1916 Bytes);
Ø4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;

ØEthernet interface supports10M/100M, half/full duplex auto-Negotiation and AUTO-MDIX

   (crossed line and  straightly connected line self-adaptable );

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

ØHave three Loop Back Mode: E1 interface Loop Back (ANA),Ethernet interface Loop Back(DIG),Command the remote

   Ethernet interface Loop Back(REM)

ØHave pseudo random code test function, easy the installation and maintenance;
ØProvide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
ØHave Ethernet monitor self-reset function, the equipment will not dead

ØEthernet interface supports the counters of receiving and transmitting frame, receives wrong frame counters.  

   E1 interface supports the counters of receiving wrong frame;

ØRealize monitor of remote equipment temperature and voltage from local equipment;
ØSupport SNMP Network Management;

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