Hello, I have made BELL202 modem using TCM3105 IC.
The circuit output part is as per IC datasheet using Simple telephone interface. My problem is the two boards connected directly RJ11 to RJ11 of other board it does communicates.
Single board when checked it communicates when 600Ω is put at secondary of transformer.
Is this right way of testing?
Kindly help
