Introduction

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.

Features

◆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)
