  • Patent number: 7761560
    Abstract: A method of content-related processing of a data flow compares the data flow with a list of known data flows, and determines whether the data flow is recognized as a known data flow. When the data flow is recognized as a known data flow, the data flow is processed as specified in the list. When the data flow is not recognized as a known data flow, successively analyzing the data flow until a content type of the data flow is sufficiently recognized in order to decide how to process the data flow.

  • Publication number: 20060046708
    Abstract: The invention relates to a device and a method for controlling an authentication in a telecommunications network, using a subscriber connection device for connecting a user region to an exchange by means of an external data transmission interface and for implementing an internal data transmission interface in the user region, the external data transmission interface comprising at least one authentication channel. A control unit is used to monitor switched data traffic on the external and/or internal data transmission interface and controls respective logon/logoff processes in the authentication channel to an internet service provider, according to the monitored switched data traffic.

  • Publication number: 20050129227
    Abstract: The invention relates to a method for pre-qualifying subscriber connection lines for broadband services. According to said method, a mathematical characterisation of the physical behaviour of the subscriber connection line is obtained by applying a signal to the subscriber connection line to be tested and the output signal is then observed. Conclusions concerning relevant parameters of the subscriber connection line are inferred from said mathematical characterisation with the help of a classical physical models. A combined time-frequency representation, the Weil transformation according to “A. Weil, Basic Number Theory, Grundlehren der mathematischen Wissenschaften, Bd. 144, Springer 1985”, is used to obtain a statistically solid estimation of the aforementioned mathematical characterisation.

  • Publication number: 20050063499
    Abstract: The invention relates to a data reception method, a data communication system, and to a receiver or transmitter/receiver device that is adapted to receive modulated transmission signals from a transmitter or an additional transmitter/receiver device via a transmission channel. Synchronization data is transmitted by means of the transmission signals which are used to synchronize the receiver device. The receiver or transmitter/receiver device is provided with an equalizer which equalizes the received or derived signals. The inventive method is further characterized in that the same transmission signals with which the synchronization data is transmitted are used to adjust the equalizer.

  • Patent number: 6628762
    Abstract: In order to prevent occurrence of an interruption of a transmission of a high-bit-rate digital signal due to specific signals during simultaneous transmission of the high-bit-rate digital signal and of signals of a standard telephone connection between a public exchange and a subscriber-side terminal, an information signal is output before the occurrence of such a special situation and, as a result of the information signal, the transmission of the high-bit-rate digital signal is modified in a suitable way for the duration of the special situation.
