Vorrichtung und Verfahren zum Anpassen der Leitungseigenschaften bei hochbitratigen Datenübertragungen

摘要

The invention relates to a line module (2) for a local exchange (1) for connecting terminals (7) to a telecommunications network. Said module comprises a determining device (4) for determining the impedance of the subscriber line (6) provided with terminals (7) connected thereto, and comprises a matching device (5) for automatically matching the impedance of the line module (2) to the determined impedance. The invention also relates to a method, which is used in this line module and which is provided for adapting the line module (2) to a subscriber line (6) provided with terminals (7) connected thereto.
