ABSTRACT:
Data transmission network having a least one line termination device connected via a data transmission medium to several network termination devices, each network termination device comprising a request message generator for generating a data transmission request message when a data communication device connected to the network termination device is sending data, and an xDSL transceiver for transmitting an upstream data frame including the generated request message via the data transmission medium to the line termination device. The line termination device includes a selection unit for selecting network termination devices which have sent a request message depending on stored status information data of the network termination devices, a grant message generator for generating data transmission grant messages for the selected network termination devices, and an xDSL transceiver for broadcasting downstream data frames including the generated grant messages via the data transmission medium to the network termination devices.
