Abstract:
1. A network in a motor vehicle, wherein the network comprises; a central subscriber; and at least one first subscriber, wherein the central subscriber and the at least one first subscriber are connected by at least one first cable, wherein the central subscriber comprises at least one signal coupling unit and at least one energy coupling unit, wherein the signal coupling unit is used to impress or to tap off an AC voltage onto or from at least one first line of the first cable, wherein the energy coupling unit is used to impress a first DC voltage at a first predetermined voltage level onto the first line of the first cable and a further DC voltage at a further predetermined voltage level onto a second line of the first cable, wherein the at least one first subscriber comprises at least one signal coupling unit and at least one energy coupling unit, wherein the signal coupling unit is used to tap off or to impress an AC voltage from or onto the at least one first line of the first cable, wherein the energy coupling unit is used to tap off the first DC voltage from the first line of the first cable and the further DC voltage from the second line of the first cable, wherein the first DC voltage is a first operating voltage for the first subscriber or is transformed into the first operating voltage for the first subscriber, wherein the first operating voltage is applied to at least one first input of the first subscriber, wherein the further DC voltage is a further operating voltage for the first subscriber or is transformed into the further operating voltage, wherein the further operating voltage can be applied to the first input or to a further input of the first subscriber, and wherein the first predetermined voltage level of the first DC voltage is different than the further predetermined voltage level of the further DC voltage.
