Figure 12 Connection of ALIS-A to the Telephone Line
As shown in the figure, ALIS-A requires a minimum of components to complete the DAA:
- Protection circuit: not shown.
- Bridge: using Schottky diodes will improve the performance at low feeding conditions.
Recommended: Dual Schottky diode SIEMENS BAT 240A.
- Resistors for current sensing.
- Capacitors for AC coupling and VDD buffering.
