I have tried by coupling the signals trough
a 600 ohm 1:1 transformer to the line. A 600 Ohm 1:1 transformer directly connected to the telephone line will immediately saturate due to DC loop current. You must use a 0.1uF 250V capacitor in series with each winding of the transformer. Is not there any application circuit in the datasheet? |
