AN-FE1-RS485 is E1 G.703/G.703 framed / fractional n x 64 K  to RS485 converter that realizes data conversion between ITU-T G.703 standard E1 G.703  and 1 x RS485 interface. Date interface mode is DCE, could connect to DTE or DCE device, RS485 can transmit asynchronous 0~115200Kbps self-adapting speed.

• AN-FE1-RS-485 can realize long-distance monitoring of this end equipment to the far-end equipment (two-row indicator, upper row indicate local status, lower row indicate far-end status);
• RS485 rate support 0~115200Kbps self-adapt
• RS485 support hot-plug, connection to DTE or DCE device;
• Offers 2 kinds of loop-return function, namely E1 self-looping at local end (ANA) and RS485 self-looping at local end (REM)
• n x 64 kBit/s time slot selection at E1 line, framed / fractional E1 support;
• AC220V and DC-48V for option, and DC-48V is  not divided into positive and negative pole with simple installation and maintenance; 
• Supports  function of pseudo-random code testing(PATT), which brings great convenience for installation, debugging and maintenance of equipment;
• E1 interface supports 75Ω unbalanced and 120Ω balanced impedance at the same time;
• Realizes SNMP network management function in our chassis installation (check central platform here)

• E1 self-looping at local end (ANA); self-looping at remote end(REM)
