Abstract:
1. A method for transmitting transmit data using a subscriber modem of a number of subscriber modems connected via subscriber lines bundled in a cable bundle to associated switch modems of a switching office within a subscriber access network with adapted transmit power, the method comprising the following steps: (a) selecting at least one transmission frequency band from possible transmission frequency bands used by the other subscriber modems of said number of subscriber modems; (b) subdividing the selected transmission frequency band into a number of subfrequency bands; (c) determining the maximum transmit power associated with each subfrequency band of the selected transmission frequency band; (d) transmitting the transmit data with an adapted transmit power from the subscriber modem via an associated subscriber line to the associated switch modem, wherein, in a single-carrier operating mode, the transmit data are transmitted with a uniform transmit power selected as the lowest transmit power from the maximum transmit powers determined in all subfrequency bands of the selected transmission frequency band, and wherein, in a multi-carrier operating mode, the transmit data are in each case transmitted in the subfrequency bands with the determined associated maximum transmit power.
