Product Description
This interface converter provides one unframed 2048K E1 or framed n*64Kbps 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.
Functional Properties
?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 timeslotHave 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 (4096) 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 remoteEthernet interface Loop Back(REM)
?Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
?Ethernet supports standard IEEE802.3af / at power supply; Each port can be sufficient power output 15.4W (IEEE802.3af) at 25.5W (IEEE802.3at);
