Abstract:
A process for determining an echo coupling factor (CF) between the signals on a transmission path (1) in the transmitting direction and on a transmission path (2) in the receiving direction, and an echo delay time (i) of a transmitted signal (x(k)) and a received signal (y(k)) originating from the transmitted signal, the echo, in a telecommunication system consisting of transmission links with different transmission functions, and in which an information exchange takes place between a local subscriber (X), and a subscriber (Y) at the remote end of a transmission link, and in which at least one subscriber (X), (Y) is assigned an echo suppressor (5), the parameters of which are set via a control circuit (6) as a function of the echo coupling factor (CF) and the echo delay time (i), characterised in that during the information exchange between the local subscriber (X) and the subscriber (Y) at the remote end of the transmission link, characteristic states and time segments of the information are determined, upon which the measurement of the echo coupling factor (CF) and the measurement of the echo delay time (i) are rendered dependent.
