Unframed E1 Optical Ethernet Converter

●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 force the remote device rate to follow it
●Have the function of E1 interface loopback check, to avoid the converter crashing because of interface loop  return;
●Have an indicator light when the device is power-off or the E1 line is broken or loses signal;
●Can set the E1 line not to send the LINK signal to the Ethernet interface while the E1 line is broken;
●The Ethernet interface supports jumbo frames (2036 Bytes);
●Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering 
●Ethernet interface supports 100M, full duplex, support VLAN
●Have the Ethernet monitor self-reset function, the equipment will not dead
●The local device can force the remote device rate to follow it ( valid when framed)
●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)－－-Optical Ethernet Modem(B)－－-Ethernet Optical Fiber  Transceiver (C), can manage (B) and (C) at (A)
