Name:Framed E1-FE Converter

Product Description


This interface converter is based on FPGAproviding one framed E1 interface and one Ethernet interface to achieve 10/100base-T Ethernet data transmission on the E1 channel. It is a high performance self-learning Ethernet bridge. This device is the extension device of Ethernet using network (PDH/SDH/Microwave) that provide E1 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.


based on self -copyright  IC 
Can realize monitor and control of remote equipment OAM management data did not  take up user's timeslot and save E1 bandwidth
E1 supports any timeslot set the rate is 64K-2048K
The local device can forced the remote device rate follow it
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 (2036 Bytes);
Inter-set dynamic Ethernet MAC address (4096) with local data frame filtering 

Ethernet interface supports10M/100M half/full duplex auto- Negotination and AUTO-MDIX

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

◆ Have Ethernet monitor self-reset function the equipment will not dead
◆ Can achieve the remote device setting any 5 mode of Ethernet and can closed the AUTO-MDIX function; 
◆ 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;
◆ Support SNMP Network Management;
◆ Can realize monitor of remote equipment temperature and voltage from local equipment;  
◆ Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber Modem (C) 

◆ Can form the structure: Ethernet E1 Bridge(A)---Optical Ethernet Modem(B)---Ethernet Optical Fiber Transceiver (C), can manage (B) and (C) at (A)
