Unframed E1-FE Converter

Type:FCC-E1F1 Message

Description:1channel unframed E1 - FE converter，With E1 loopback detection function

Product 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.

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 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)
