E1 time slot mux / 30 FXS/FXO over E1 converter
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;
