Overview
E-link E1-4ETH interface converter is based on FPGA. The device provides the transition between ITU-T G.703 (E1) standard unframed 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
Features
►Based on self -copyright IC
►Can realize monitor and control of remote equipment, OAM management data did not take up users' timeslot and save E1 bandwidth
►Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop return;
►Have indicator when the device is power-off or E1 line is broken or lose signal;
►Can set the E1 line that not to send the LINK signal to Ethernet interface while 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 pseudo random code test function, easy the installation and maintenance;
►Provide 2 impedance: 75 Ohm unbalance and 120 Ohm balance;
►Have 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 wrong frame;
►Realize monitor of remote equipment temperature and voltage from local equipment;
►Support SNMP Network Management;
►Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber Modem (C)
