Cable discharges into communication interfaces

Current amplitudes of a cable discharge event (CDE) are a risk for electronic interfaces if a cable can discharge directly into a signal pin. CDE have been recorded for several cables in different configurations. CDE can be modeled by square pulses, thus, Transmission Line Pulsing is a good approach for characterizing interface pins and protection elements.
