Question: 
If official election results processed by an electronic tabulation system, at which level results are entered into an electronic tabulation system?
Answer: 
Polling station level, offline
Comments: 

At the polling station level, the voting machine counts the votes (tally list). The results are recorded in a media (like a pen drive). This media is then physically transported to a desktop computer with a private link, to transmit the results to a central database. This central database processes the results at the state level, if the disputed positions are president/governor/senator/deputies, or at the municipality level, if the disputed positions are mayor/city counsellors.
