John: This article (https://wodewangzhishime.blogspot.com/2024/02/httpswodewangzhishime.html) say that parallel in out line is a branch of the Clock line of RJ 45.

Me: OK.

John: Look at the picture above. Do you see a frequency mixer? This mixer mix the frequency of the output of the modulator and the clock line of RJ45.

Me: OK.

John: Originally, the modulator output 3-2-1-4, and then, input them to a - b - c - d. Because, the parallel in out line is the branch of the clock line of RJ45. If the clock line of RJ 45 is hacked by hackers. Hackers can change 3-2-1-4 into 0-4-0-4. Consequently, the input to a - b - c - d is 0 , 4, 0, 4.

Me: Take a look at this article . (https://kamchihau.blogspot.com/2024/07/sequential-109.html) .
