Can you help me undestanting how to uses the calculator?
The first issue I found is how to make it work with PVDM3 or VWIC3, then what do I need to write in each part.
Finally how to interpret the output.
I want to know if whit the below information I can support two E1 (32 channels each)

I read the help guide, but I dont quite understand this. 
VWIC3-2MFT-T1/E1 is the card that will allow you to connect 2 seperate E1 circuits to it.
PVDM3-32 will allow conversion from TDM (E1) to voip, depending on which codec you are going to use each call will either use 1 PVDM channel (low/medium complexity i.e. G711), or 2 channels (high complexity, i.e. G729R8).
HTH,
