The N operational devices and the reserve device are interconnected with each other. The redundant system includes a system control integrated within one of the devices of the redundant system. The redundant system further includes switches that are associated with the operational devices. In case of a failure of a respective operational device, the system control is configured to cause at least one of the devices to operate the switch associated with the respective operational device having the failure. Further, a method of operating a redundant system for processing at least one signal is described. ## Claims ### Claim 1 A redundant system for processing at least one signal, wherein the redundant system has N+1 devices that comprise N operational devices and one reserve device, wherein the N operational devices and the reserve device are interconnected with each other, wherein the redundant system comprises a system control integrated within one of the devices of the redundant system, wherein the redundant system further comprises switches that are associated with the operational devices, and wherein, in case of a failure of a respective operational device, the system control is configured to cause at least one of the devices to operate the switch associated with the respective operational device having the failure. ### Claim 2 (depends on 1) The redundant system according to claim 1, wherein the reserve device is made operational by operating the switch associated with the respective operational device having the failure while removing the respective operational device having the failure from operation. ### Claim 3 (depends on 1) The redundant system according to claim 1, wherein the at least one of the devices, which operates the switch associated with the respective operational device having the failure, is the adjacent device of the respective operational device having the failure. ### Claim 4 (depends on 1) The redundant system according to claim 1, wherein two switches are associated with each operational device, wherein one of the two switches is associated with an input side and the other one is associated with an output side of the respective operational device. ### Claim 5 (depends on 4) The redundant system according to claim 4, wherein both switches associated with the input side and the output side are operated simultaneously. ### Claim 6 (depends on 1) The redundant system according to claim 1, wherein the system control is monitoring all devices. ### Claim 7 (depends on 1) The redundant system according to claim 1, wherein the system control automatically controls the at least one device such that the at least one device initiates the switching operation of the switch associated with the respective operational device having the failure. ### Claim 8 (depends on 1) The redundant system according to claim 1, wherein another device is enabled to provide the system control in case of failure of the device initially providing the system control. ### Claim 9 (depends on 1) The redundant system according to claim 1, wherein the system control is initially integrated within the reserve device. ### Claim 10 (depends on 1) The redundant system according to claim 1, wherein the interconnection between the devices of the redundant system is established by a control bus. ### Claim 11 (depends on 10) The redundant system according to claim 10, wherein the control bus is an Ethernet bus or a CAN bus. ### Claim 12 (depends on 1) The redundant system according to claim 1, wherein each operational device of the redundant system is connected with at least one dedicated input switch that is associated with an input side of the respective operational device. ### Claim 13 (depends on 1) The redundant system according to claim 1, wherein each operational device of the redundant system is connected with at least one dedicated output switch that is associated with an output side of the respective operational device. ### Claim 14 (depends on 1) The redundant system according to claim 1, wherein each switch has four ports. ### Claim 15 (depends on 1) The redundant system according to claim 1, wherein the redundant system is a broadcasting system, an air traffic control system or a satellite communication amplifier system. ### Claim 16 A method of operating a redundant system for processing at least one signal, wherein the redundant system has N+1 devices that comprise N operational devices and one reserve device that are interconnected with each other, the method comprising: detecting an occurring failure in one of the operational devices by a system control integrated within one of the devices of the redundant system, and causing at least one of the devices to operate a switch associated with the respective operational device having the failure. ### Claim 17 (depends on 16) The method according to claim 16, wherein the reserve device is made operational by operating the switch associated with the respective operational device having the failure while removing the respective operational device having the failure from operation.
