Default Re: Ambassador/Senator external extension adaptor

Somewhat off-topic, but still on the subject of Ambassador/Senator, I notice that whereas the Senator has three connections for each external line (marked "A", "B" and "E" for the line legs and signal earth) plus a fourth one unmarked and presumably unused, the Ambassador has four (marked "A", "B", "C" and "E"). Does anyone know the function of "C", if any?
