About the Telecommunication system takes place here next to the transfer of Voice data of telephone equipment also amplifies a transfer of Computer data instead.

To this existing structures of copper networks to exploit, are low frequency for both the Speech signals and for the higher frequency signals calculator common transmission lines used. to this Computer data and voice data via a common simultaneously To transfer line, the associated signals must both on the customer side, and in a merged exchange and after Übermittleungsstrecke be separated again. This happens for example with so-called splitter devices, of which the voice and computer signals in accordance with their different signal frequencies are separated and the particular use to be assigned. That is, it takes place an assessment of data signals through a targeted Allocation of frequency ranges of the information to be provided to data respective language participants and for processing the data detention facilities.

Such data processing facilities are so far as additive components provided to an external computer existing data signal processing systems are added. This problems arise in that such Data processing equipment with long connecting paths and a high number of electronic contact elements for Establishing the necessary connections to the data signal processing system accompanied. Thereby, the corresponding total overall system more expensive and more susceptible to interference, which the latter especially at long distances the case is. This must then by long cable paths and many Contact points have caused loss of signal power by consuming and expensive in turn gain and Suppression measures be eliminated.

In Figure 1 is a schematic structure of such Data processing system 100 in accordance with distribution device 110 the prior art shown. Thereafter, the Distribution device 110 has two separate distribution blocks 120, 130 , of which the distributor block 120 to the exclusive Transmission of voice data signals at a switching station 140 (Eg a distribution block) of a telephone switching system 150 and a splitter device 160 is connected, which turn for transmitting exclusively Computer data signals connected to a modem device 170 is, which is in communication with a computer network 180th The second distribution block 130 of the distribution device 110 is for the transmission of both computing and Voice data signals with the switchgear 190 (eg, a Distribution block) of a subscriber 200 and the Splitter device 160 is connected. At this Telecommunications system are proceeding from the participant 200 Computer- and voice data signals on a common line 210 received the second manifold block 130 and from this a manifold 220 to the splitter device 160 forwarded. Of the 160 Splittereinichtung be the Voice and computer data signals separated, said forwarded computer data signals to the modem device 170 be and the voice data signals to the first manifold block are forwarded 120, from which they then the Telephone switching system 150 are supplied. In the reverse Trap by the telephone switching system 150 via the first manifold block 120 incoming voice and data signals arriving from the computer network via the modem 170 Computer data signals from the splitter device 160 together and through the second distribution block 130 to the Participants 200 passed. At this Telecommunications system 100 are connecting lines 220, 230 with associated connections both between the first Manifold 120 and the splitter device 160 and between the second manifold block 130 and the Splitter device 160 required.
