Unframed E1-4FE Converter

Type:FCC-E1F4 Message

Description:1channel unframed E1 - 4FE converter ，With E1 loopback detection function

Product Description
             E1-4ETH interface converter is based on FPGA. The device provides the transition between ITU-T G.703 (E1) standard unframed E1 interface and 10/100Base-T interface. It is a high capability, self-adaptable long-distance Ethernet bridge. The product is small and with low cost. It is widely used in connecting between WAN and LAN, monitoring, etc
Functional Properties
Ø Based on self -copyright  IC 

Ø   Can realize monitor and control of remote equipment, OAM management data did not take up users’  

      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  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 (1916 Bytes);
Ø   4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;

Ø   Ethernet interface supports10M/100M, half/full duplex auto-Negotiation and AUTO-MDIX (crossed line and  straightly 

      connected line self-adaptable );

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   Have pseudo random code test function, easy the installation and maintenance;
Ø   Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
Ø   Have Ethernet monitor self-reset function, the equipment will not dead

Ø   Ethernet interface supports the counters of receiving and transmitting frame, receives wrong frame counters.  E1 interface supports 

      the counters of receiving wrong frame;

Ø   Realize monitor of remote equipment temperature and voltage from local equipment; 
Ø   Support SNMP Network Management;
Ø   Can form the structure: Ethernet E1 Bridge(A)－－-E1 Optical Fiber Modem(B)－－-Ethernet Optical Fiber Modem (C)
