Abstract: Embodiments of the present invention provide a method for activating a DSL. The method includes: sending, by a central office equipment, a sync frame period indication message to a customer premises equipment, where a sync frame period indicated by the sync frame period indication message is smaller than a specified sync frame period threshold; receiving a reply message sent by the customer premises equipment in response to the sync frame period indication message, where the reply message indicates whether the customer premises equipment accepts the sync frame period indicated by the sync frame period indication message; and if the reply message indicates that the customer premises equipment accepts the sync frame period, performing, by the central office equipment, vectoring training by using a corresponding sync frame within the sync frame period. The embodiments of the present invention further provide corresponding equipments, a system, and a program product.

Abstract: Embodiments of the present invention provide a signal transmission method. The method includes: sequentially rotating phases of to-be-sent signals on a line set 1 by different angles and in relative to phases of to-be-sent signals on a line set 2, and sequentially sending, to a user side, the to-be-sent signals whose phases are rotated. The method also includes receiving a rotation factor that is of a high-quality received signal on the line set 1 and that is fed back by the user side, where the high-quality received signal includes a received signal with a high signal-to-noise ratio or high power. The method also includes using the rotation factor fed back by the user side as a fixed rotation factor, and rotating, according to the fixed rotation factor, a phase of a signal to be subsequently sent on the line set 1.
