E1 to Ethernet Protocol/Inerface Converter,Ethernet over PDH Fiber Multiplexer

TThis interface converter provides one unframed 2048K 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 
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)
