Patent ID: 7079572

Claim:
A method for setting up a data transmission link between a first xDSL transceiver and a second xDSL transceiver, comprising the following steps: a) sending of an echo adjustment signal by the first xDSL transceiver to the second xDSL transceiver until an echo cancelation circuit of the first xDSL transceiver is set, during which the second xDSL transceiver synchronizes itself to the echo adjustment signal and the second xDSL transceiver is not sending a signal; b) sending of a first synchronization signal via the first xDSL transceiver to the second xDSL transceiver for synchronizing the second xDSL transceiver, the first synchronization signal being different from the echo adjustment signal; c) sending of a second synchronization signal by the second xDSL transceiver to the first xDSL transceiver for synchronizing the first xDSL transceiver when the second xDSL transceiver is completely synchronized by the first synchronization signal and the first synchronization signal is detected as such, the second synchronization signal being sent by the second xDSL transceiver to the first xDSL transceiver until an echo cancelation circuit of the second xDSL transceiver is set, d) sending of a first indicating signal by the second xDSL transceiver to the first xDSL transceiver, which indicates to the first xDSL transceiver that the echo cancelation circuit of the second xDSL transceiver is set and the second xDSL transceiver is synchronized; e) and sending of a second indicating signal by the first xDSL transceiver to the second xDSL transceiver which indicates to the second xDSL transceiver that the first xDSL transceiver is synchronized when the first xDSL transceiver has received the first indicating signal.
