ABSTRACT:
The invention relates to a method and an apparatus for determination of parameters for a transmission path in a telecommunications system by a transmitting/receiving apparatus having a transmitter and a receiver. In order to determine transmission parameters, a transmission signal is transmitted via the transmission path at a predetermined transmission power level and at a predetermined baud rate (fT) and an echo signal is sampled. A correlation function is calculated from the echo signal and from a correlation signal in a correlation function stage, an envelope function for the correlation function is calculated in an envelope function stage, the envelope function is evaluated, and an output signal is produced as a function of the relative timing and amplitude of the line start echo and/or of the line end echo in an evaluation stage.
