Framed E1 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 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 (4,096) 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)
