Unframed E1-FE Converter
型号：LNK-E1F1
►Ethernet interface supports10M/100M, half/full duplex；
►Support SNMP Network Management;
►Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
►Provide 2 clock types: E1 master clock and E1 line clock;
Overview
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
►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)
