METHOD AND DEVICE FOR DIGITAL SUBSCRIBER LINE INITIALIZATION

Embodiments of the present invention provide a method and an apparatus for digital subscriber line initialization, where the method is performed by a subscriber side transceiver on a showtime line. The method includes: receiving a first notification message sent by a vectoring control entity VCE, where the first notification message includes first indication information, the first indication information indicates at least one first index, and an element of the at least one first index in a joining uplink pilot sequence is 1 or -1; and converting a first uplink pilot sequence of the showtime line into a second uplink pilot sequence according to the first notification message; and sending the second uplink pilot sequence to a central office transceiver on the showtime line. Therefore, in the embodiments of the present invention, crosstalk suffered when a central office transceiver on a joining line detects an uplink pilot signal is reduced, so that noise can be reduced, a signal-to-noise ratio can be increased, and strength of detecting a synchronization symbol by the central office transceiver on the joining line can be further improved.
