Unframed E1 Optice Ethernet Converter

Type:FCCM-E1 Message

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

Product Description
             This interface converter is based on FPGA providing one unframed E1 interface and one Ethernet interface to achieve 10/100base-FX 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
Ø based on self -copyright  IC 
Ø Can realize monitor and control of remote equipment OAM management data did not  take up user’s  timeslot and save E1 bandwidth
Ø Have the function of E1 interface loop back check avoid the converter crashed because of interface loop  return;
Ø   Have indicator light when the device is power-off or E1 line is broken or lose signal;
Ø   Can set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken;
Ø   The Ethernet interface supports jumbo frames (2036 Bytes);
Ø   Inter-set dynamic Ethernet MAC address (4096) with local data frame filtering 
Ø   Ethernet interface supports100M full duplex support VLAN
Ø   Have Ethernet monitor self-reset function the equipment will not dead
Ø   Provide 2 clock types: E1 master clock and E1 line clock;

Ø Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command  

     the remote Ethernet interface Loop Back(REM) 

Ø Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
Ø Support SNMP Network Management;
Ø Can realize monitor of remote equipment temperature and voltage from local equipment; 

Ø Can form the structure: UTP Ethernet E1 Bridge(A)---Optical Ethernet E1 Bridge(B)---Ethernet Optical   

      Fiber Transceiver (C) can manage (B) and (C) at (A)
