The present disclosure provides for carrying downstream mapping information in an echo request message andor echo reply message, which can describe both IP multipath information and label multipath information. At least one drive connector is positioned on the first surface of the circuit board. A high heat exchange capacity is thus achieved by exploiting both the high specific heat of the water and the high latent heat of liquefaction of the water contained in the heat store. A particular member is provided with content including a text phrase in a first language, and the member requests translation into another language. The circuit is provided with a pole of an output potential which is connected centrally in the series connection.
