Digital subscriber line connection method, involves making available digital subscriber line upward channel and downward channel, and amplifying upper frequency range of downward channel using amplifier

摘要

The method involves making available a digital subscriber line (DSL)-upward channel (13) for data transmission from a customer connection to a switching center, and a DSL-downward channel (14) for a reverse data transmission. The downward channel lies in a part of a high frequency range, as the upward channel. Upper frequency range of the downward channel is amplified by an amplifier.
