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.

14. Subscriber linecard for connecting subscriber terminals to a data network having:
-
a) a network processor which is connected to the data network by means of a network interface; b) at least one voice signal processor for voice signal processing, where the at least one voice signal processor comprises at least one digital signal processor configured to generate signaling systems, compensate for echo signals and perform data compression operations and where the at least one digital signal processor is connected in parallel to the subscriber terminals via subscriber ports; c) at least two busses connected between the network processor and the at least one voice signal processor for transmission of telephone data; i) a control bus used to transmit control signals for setting up telephone connections between subscriber terminals; and ii) a voice data bus, processor signal processor, and being separated from the control bus, for transmitting voice data packets, where the voice data packets are transmitted in split form in multiple time-division multiplex data frames which each have a predetermined number of timeslots, where timeslots intended for the at least one voice signal processor are provided within the multiple time-division multiplex data frames, and where the voice data packets each comprise a payload of voice data having a variable scope or volume. - View Dependent Claims (15, 16, 17, 18, 19)
