ABSTRACT:
A method for transmitting digital voice data packets between voice data inputs of a plurality of channels (A B, C, D) and a transmitter comprises the following steps: compressing the voice data packets to compressed data packets in a vocoder assigned to every channel, feeding the compressed data packets of every channel to a control device, unsolicited, unsynchronized transmission of the compressed data packets on a data bus common to all channels from the control device to a processor assigned to the transmitter, combining a defined number of compressed data packets of a certain channel which have been transmitted last on the data bus to a transmission block by means of a processor, a last compressed data packet being fed to the transmission block only when the transmission of the transmission block has already started.
