Abstract:
1. Data transmission method for transmitting voice data packets between at least one voice signal processor and a network processor using a voice data bus in time-division multiplex data frames which each has a predetermined number of timeslots, the method comprising: transmitting voice signal data between the voice signal processor and at least one subscriber port connected in parallel thereto; transmitting the voice data packets from the at least one voice signal processor in split form distributed to multiple data frames via the voice data bus in particular timeslots provided for the at least one voice signal processor within the multiple data frames; and transmitting control data for setting up telephone connections between subscriber terminals between the at least one voice signal processor and the network processor via a control bus being separated from the voice data bus; wherein the at least one voice signal processor comprises a digital signal processor configured to generate signaling systems, compensate for echo signals and perform data compression operations and the voice data packets each comprise a payload of voice data having a variable scope or volume.
