Best quality Usb To Rs485 422 Converter - Framed E1-4FE interface Converter JHA-CE1fF4 – JHA

Framed E1-4FE interface Converter JHA-CE1fF4

Overview

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

Features

• Based on self -copyright  IC 
• E1 supports any timeslot set, the rate is 64K-2048K
• Can realize monitor and control of remote equipment, OAM management data did not  take up user’s  timeslot and save E1 bandwidth
• Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop  return; 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 (1916 Bytes);
• 4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;
• Ethernet interface supports10M/100M, half/full duplex auto-Negotiation and AUTO-MDIX(crossed line and  straightly connected line self-adaptable );
• Provide 2 clock types: E1 master clock and E1 line clock;
• Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM)
• Have pseudo random code test function, easy the installation and maintenance;
• Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
• Have Ethernet monitor self-reset function, the equipment will not dead
• Ethernet interface supports the counters of receiving and transmitting frame, receives wrong frame counters.E1 interface supports the counters of receiving wrong frame;
• Realize monitor of remote equipment temperature and voltage from local equipment;
• Support SNMP Network Management;
• Can form the structure: Ethernet E1 Bridge(A)－－-E1 Optical Fiber Modem(B)－－-Ethernet Optical Fiber Modem (C)
