Method and data transmission device for data transmission within an xDSL data transmission system connecting at least two ethernet networks via xDSL links
An xDSL data transmission system which comprises at least two xDSL data transmission devices that connect at least two Ethernet networks to the xDSL data transmission system. For transmitting payload data via an xDSL transmission link formed between two adjacent xDSL data transmission devices, a respective xDSL data transmission frame according to a first protocol stack is used, in which additionally an embedded operations channel is provided according to the first protocol stack. A second protocol stack different from the first protocol stack is provided according to which an access to the embedded operations channel within an xDSL data transmission device is executed, and management data for diagnostics and configuration of the xDSL data transmission system are added to, transferred within, and read from the embedded operations channel, independently of the payload data of the xDSL data transmission frame.
