This is because the "no change" state is not allowed within the bit length. When the data bits sent by multiple zero-power terminals at the same time have different values, the rising and falling edges of the reception cancel each other out, resulting in an uninterrupted carrier signal within the entire bit length. Since this state is not allowed, the network device uses This error can determine the specific location of the collision.
