8e1 to 4 Ethernet Converter Fiber Optical Equipment China Manufacturer

8E1 to 4Ethernet converter
DESCRIPTION
This 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.
FEATURES
N Based on self -copyright IC
N Support unframed mode (2048K) set and can manage the remote device condition, OAM management data did not take up user's time slot
N Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop back;
N Have indicator when the device is power-off or E1 line is broken or lose signal;
N Can set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken;
N The Ethernet interface supports jumbo frames (2036 Bytes);
N Inter-set dynamic Ethernet MAC address (4, 096) with local data frame filtering
N Ethernet interface supports10M/100M, half/full duplex auto- Negotiation and AUTO-MDIX (crossed line and straightly connected line self-adaptable );
N Have Ethernet monitor self-reset function, the equipment will not dead
N Can achieve the remote device setting any 5 mode of Ethernet and can closed the AUTO-MDIX function;
N Provide 2 clock types: E1 master clock and E1 line clock;
N The local device can forced the remote device rate follow it(when the device is unframed mode, that is invalid)
N Have three Loop Back Mode: E1 interface Loop Back (ANA), Ethernet interface Loop Back(DIG), Command the remote Ethernet interface Loop Back(REM)
N Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
N Support SNMP Network Management;
N Can realize monitor of remote equipment temperature and voltage from local equipment;
N Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber Modem (C)
N Can form the structure: Ethernet E1 Bridge(A)---Optical Ethernet Modem(B)---Ethernet Optical Fiber Transceiver (C), can manage (B) and (C) at (A)
