    摘要: This invention relates to power control arrangements of digital subscriber lines. The invention controls parallel subscriber lines simultaneously in an organized way, based on the measurements of crosstalk conditions of the sub-scriber lines. Different crosstalk conditions are measured. The organized way to control the transmission power levels ensures that the crosstalk does not increase to an unacceptable level in each of the subscriber lines.
