Abstract: A method for handling interference during the transmission of a chronological succession of digital images (I) from a sender (S) to at least one receiver (R), in which the images to be transmitted show the face of a Speaker at least intermittently, involves images in the chronological succession that are unable to be decoded, or unable to be decoded satisfactorily, on account of the interference being replaced by synthentic images (P) at the receiver. The synthetic images are produced using phonetic data (LD) that are or have been extracted from digital voice data (SD) for the Speaker by means of phonetic recognition, the digital voice data being or having been transmitted together with the digital image data (I).

Abstract: A method is specified for the handling of a telecommunications connection between at least two subscribers, wherein the telecommunications connection has a signalling Channel for transmission of a signalling stream and a payload Channel for the transmission of a payload stream, wherein frequency-coded Signals are transmitted in the payload stream, wherein at least one subscriber among the at least two subscribers is assigned to a network which has a switching device and a signal processing device provided separately from the switching device, and wherein the frequency-coded Signals are recognized in the signal processing device and are transmitted independently of the payload stream to the switching device. The invention also relates to a telecommunications arrangement, a switching device and a network coupling device.

Abstract: In a telecommunication system having a remote administration function, a virtual terminal having the properties of a terminal with administration authorization is defined. The data stream to and from the virtual terminal being diverted to a remote computer connected to the telecommunication system.
