摘要： he invention relates to a line terminator unit (100) for a subsc riber line (4) which transmits and receives broad-band signals via a single subscriber line. Said broad-band signals are composed of a broad-band or narrow-band low-frequency voice signal and a broad-band higher-frequency data signal. The frequency bands of the voice signal and the data signal substantially do not overlap. The inventive line terminator unit is provided with a digital frequency separating filter in the digital part of the line terminator unit. Said frequency separating filter is arranged in the digital part of the line terminator unit and serves to distinguish between the low-frequency voice signal and the higher-frequency data signal. The line terminator unit is especially useful for separating an ISDN or POTS voice signal from an ADSL data signal.
