Data-transmission device and method for transmitting data with a reduced outage risk

摘要

A data-transmission device has a number of N uplink interfaces routable to an output element over a processing line provided with data-processing components. A first processing line and a second processing line are provided each having two separate processing rows for in each case N/2 data lines. Each processing line has a circuit arrangement by means of which the N/2 data lines connected to the processing line can be connected to the respective other processing line to one of the two processing rows available there. The circuit arrangements is controlled in such a way that one of the two processing lines is active and the respective other can be switched to a standby mode so that the data traffic waiting at the N uplink interfaces can be handled via one of the two processing lines.
