The robustness of transmission of the single-ended "reset" signal through the Token Ring of the CMS Preshower

There is no strong DC link between the individual modules, "ladders" of the Preshower. Non-negligible DC-offsets may occur between the grounds of adjacent ladders in a same Control Ring. Such offset is a potential threat to the reliability of the transmission of the single-ended Reset signal between these ladders. With a computational model, it is shown that the possible offsets we may obtain, are still on the safe side. Hence, confusing extra connectivity is not needed.
