Abstract:
1. A method comprising: a first adapting phase wherein vectoring of a vectored group is adapted using non-payload data carrying signals to reduce the influence of crosstalk induced from a communication connection to be added to the vectored group to at least one communication connection of the vectored group, after said first adapting phase, an xDSL initialization phase wherein data transmission on said communication connection to be added to the vectored group is at least partially initialized, after said xDSL initialization phase, a second adapting phase wherein the vectoring is adapted to reduce the influence of crosstalk induced from at least one communication connection of the vectored group to the communication connection to be added to the vectored group, and transmitting payload carrying signals on the communication connections of the vectored group, wherein vector training signals are transmitted on the communication connection to be added to the vectored group at the same time as the non-payload data carrying signals are transmitted on the communication connections of the vectored group, wherein signals with reduced or no transmit power are transmitted on the communication connection to be added to the vectored group.
