Abstract
In the line terminating device, which is provided for transmitting and receiving narrowband low-frequency voice signals and broadband data signals at a higher frequency, the analog reception path is subdivided into two separate analog paths () for voice and data using a balance filter (), which is used for data signal echo cancellation. In the transmission direction, the voice signal path and the data signal path are separated in the digital part by means of digital filters (). The invention is used for voice and data signal separation in xDSL methods, for example, ADSL.Lite.
