摘要： The invention relates to a line terminating device for a subscriber line which transmits and receives broadband signals via a single subscriber line, a broadband signal being composed of a broadband or narrowband audio-frequency data signal and a broadband higher-frequency data signal and the frequency bands of the voice signal and of the data signal essentially not overlapping. The line terminating device according to the invention has a digital frequency separating filter in the digital section of the line terminating device, which is arranged in the digital section of the line terminating device so that the audio-frequency voice signal is separated from the higher-frequency data signal. In particular, the line terminating device is suitable for separating an ISDN or POTS voice signal from an ADSL data signal.

摘要： In the broadband network access device for transmitting narrowband, low-frequency voice signals and broadband, higher-frequency data signals, the voice data is sampled in the data clock pattern and subsequently decimated. The transmission of the data which has already been decimated to the voice clock to the voice DSP (DSP) is still carried out in the data clock pattern. The conversion to the voice clock pattern is carried out in a synchronization interface (SM), directly upstream of the voice DSP. The same applies correspondingly in the opposite direction of transmission. The invention is used in xDSL methods, for example ADSL.Lite.
