  • Method and communication system for the transmission of compressed voice information in a communication network
    Patent number: 6178182
    Abstract: Given a transmission of digitized voice information (spi) compressed in originating communication systems (KS (S)) via a plurality of communication systems (KS) of a communication network (KN), the compressed voice information (spi′) is matched to the switching bit rate of the transit communication systems (KS (T)) in the systems and are switched compressed. By avoiding the decompression and repeated compression of compressed voice information (spi′), delay times and distortions of the voice information (spi) are reduced.
