Method and apparatus for adding a communication connection to a vectored group

A communication device, comprising:

• transceiver circuitry operable to communicate with another communication device over a vectored group of communication connections;
• and
• a crosstalk reduction unit operable to:
• reduce crosstalk between the communication connections in the vectored group by vectoring;
• performing a first vectoring to reduce crosstalk resulting from the influence of a joining communication connection to be added to the vectored group on the communication connections already in the vectored group by analyzing the communication connections in the vectored group without regard to crosstalk resulting from the influence of the communication connections already in the vectored group on the joining communication connection;
• and
• performing a second vectoring after at least part of an initialization phase of the joining communication connection performed after said first vectoring to reduce crosstalk resulting from the influence of the communication connections already in the vectored group on the joining communication connection.
