Abstract

The system has an adaptation device (2) for generation of a compensation signal (KS) from a received broadband signal (eBS) which is superimposed with an amplified sinusoidal signaling signal of a audio system (3). The adaptation device adds the generated compensation signal to a broadband signal (sBS) to compensate a distortion of the sinusoidal signaling signal arising during amplification of the sinusoidal signal. An independent claim is also included for a subscriber telephone exchange with a broadband system.
