Claim Text:
1. A network in a motor vehicle, the network comprising: 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 at least one signal coupling unit impresses or taps off an AC voltage onto or from at least one first line of the first cable, wherein the at least one energy coupling unit impresses a DC voltage at a predetermined voltage level onto the at least one first 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 at least one signal coupling unit of the at least one first subscriber taps off or impresses an AC voltage from or onto the at least one first line of the first cable, wherein the at least one energy coupling unit of the at least one first subscriber taps off the DC voltage from the at least one first line of the first cable, wherein the DC voltage is a first operating voltage for the at least one first subscriber or is transformed into the first operating voltage for the at least one first subscriber, wherein the first operating voltage is applied to at least one first input of the at least one first subscriber, wherein the at least one first subscriber comprises a signaling unit or the at least one first subscriber has an associated signaling unit, wherein the signaling unit can be used to produce a requirement signal in a disconnected or sleeping state of the at least one first subscriber, wherein the requirement signal can be transmitted from the signaling unit to the central subscriber via at least one line connecting the first and central subscribers.
