AN-E1-MUXlite provides conversion between ITU-T G.703 standard E1 framed interface and up to 30 FXS/FXO standard POTS analogue telephone lines.


  • E1 G.703/G.704 to POTS FXS/FXO conversion.
  • Provides two clock types: E1 master clock, E1 line clock.
  • Provides 2 kinds of loop-return function, namely E1 self-looping at local end,ordered self-loop at remote end.
  • Realize the automatically rate set of local device to remote device.
  • Has the function of pseudo-random code testing, convenient for opening of the circuit,and can be used as an error code instrument;realizes long-distance monitoring of local device to the remote device based on self-copyright IC.
  • E1 supports 75 Ohm unbalanced and 120Ohm balanced impedance at the same time.
  • Provides 30 voice channels, support calling number indication, DDI and other features.
  • Voice port supports O port and S port, O port connects switch and S port connects user’s phone.
