Features

• Based on self -copyright  IC 
• Support unframed mode (2048K) set and can manage the remote device condition ,
• OAM management data did not take up user’s timeslot
• Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop back;
• 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 (4,096) with local data frame filtering 
• Ethernet interface supports10M/100M, half/full duplex auto- Negotiation 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;
• The local device can forced the remote device rate follow it(when the device is unframed mode, that is invalid);
• 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)
