Distribution device of a data signal processing system and data signal processing system

The invention relates to a distribution device, in particular a main distributor, a data signal processing system, a data signal processing system and a cassette element for a distribution device of a data processing system.

Distribution devices are used, for example, in telecommunications systems, in particular when a larger number of subscribers are to be connected to an associated switching device. In addition to the transfer of voice data from telephone devices, there is also an increased transfer of computer data via the telecommunications system.

In order to be able to use existing copper cable network structures for this purpose, common transmission lines are used both for the low-frequency speech signals and for the higher-frequency computer signals. To do this

To be able to transfer computer data and voice data at the same time via a common line, the associated signals must be combined both on the customer side and in a switching center and separated from each other again after the transmission link. This is done, for example, with so-called splitter devices, from which the voice and computer signals are separated from one another according to their different signal frequencies and assigned to the respective use. This means that data signals are processed by a specific one

Distribution of frequency ranges of the data to be transmitted to the respective language participants as well as the facilities provided for processing the data.

Such data processing devices have hitherto been provided as additive components which are added as external components to existing data signal processing systems. This results in problems in that such data processing devices are associated with long connection paths and a large number of electronic contact elements for establishing the necessary connections to the data signal processing system. As a result, the associated overall system becomes more expensive and more susceptible to faults, the latter being the case in particular in the case of long transmission links. In this case, losses in the signal power caused by long cable routes and many contact points must be eliminated by complex and in turn expensive amplification and suppression measures.

FIG. 1 shows a schematic structure of such a data processing system 100 with a distribution device 110 according to the prior art. Thereafter, the distribution device 110 has two separate distribution blocks 120, 130, of which the distribution block 120 for the exclusive transmission of voice data signals with a switchgear 140 (e.g. a distribution block) of a telephone switching system 150 and a splitter device 160, which in turn for the transmission of only

Computer data signals is connected to a modem device 170, which is connected to a computer network 180. The second distributor block 130 of the distributor device 110 is connected to the switchgear system 190 (for example a distributor block) of a subscriber 200 and the splitter device 160 for the transmission of both computer and voice data signals. In this telecommunication system, computer and voice data signals outgoing from subscriber 200 are transmitted on a common line 210 to second distributor block 130 and are forwarded from there via a distributor line 220 to splitter device 160. The voice and computer data signals are separated by the splitter device 160, the computer data signals being forwarded to the modem device 170 and the voice data signals being forwarded to the first distributor block 120, from which they are then fed to the telephone switching system 150. In the opposite case, those of the telephone switching system 150 over the<img file="EP1290901A2_D0001.tif" />

Passive electronic components are to be understood here as components, such as resistors, capacitors, coils and the like, whereas active electronic components are to be understood as all types of semiconductor elements, such as transistors.

By means of the data signal processing unit, the data signals, which can be both analog and digital voice data and computer data signals, can be processed in the desired manner, for example divided, assigned or organized in a target-oriented manner and again combined to form a combined voice data / computer data signal in order to transmit a large number of voice and computer data signals transmitted simultaneously via the signal lines of participants.

By integrating this data signal processing unit into the distribution device, the structure of an associated telecommunication system can be greatly simplified. So those of

Telephone switching systems and networks outgoing data signals immediately, ie without the intermediary of further distribution or processing systems to the

Distribution device are routed, since the processing of the data signals is carried out by the data signal processing unit integrated in the distribution device. Furthermore, the integral training of

Distribution device with the data signal processing unit long transmission lines between distribution blocks and data signal processing unit; in particular, the

Distribution device on a reduced number of lines and associated connections, since both the subscribers as well as from the network and a telephone switching system lines can be brought directly to the distribution block of the distribution device, without any diversions to other distribution blocks and processing systems are necessary. This provides a system that is simpler overall and thus also considerably cheaper and quicker to install. The space requirement of the system is also reduced with the elimination of cables and the shortening of cable routes.

With the shorter cable routes and the smaller number of additional electrical contact points for additional electrical connections, the performance of the system is also increased and its susceptibility to faults is reduced.

For its part, the distribution device physically represents a component with sufficiently large premises and, in this regard, problem-free expansion options for accommodating additional components, so that the attachment of the electronic components of the data signal processing unit to the hardware parts, that is to say construction components, of the distributor can be implemented in a simple manner and thus at low cost is.

The distribution device thus provides the integral

Training of the distribution block with the data signal processing unit and the short interconnection and line paths achieved thereby and reduced number of electrical contact points represent a powerful, yet less prone to failure system for use in a data signal processing system.

With the distribution device according to the invention, a secure separation from respective subscribers is also achieved, since the division and thus the breakdown of their data signals takes place in an access-safe manner within the distribution device which is not accessible to third parties.

The distributor device according to the invention can be provided for connecting copper lines connected to the associated

Cable clips, preferably insulation displacement clips, are attached, which in turn are arranged in one or more rows (s) on the respective functional element, forming one or more terminal strips. Alternatively, the functional elements can also be designed to accommodate coaxial cables and optical waveguide cables. According to one embodiment, the distributor device is designed as a hybrid distributor which has functional elements for receiving all three types of lines mentioned, ie copper, coaxial and light guide cables.

According to a preferred embodiment of the invention, the data signal processing unit has a filter arrangement

High and / or low and / or bandpass filters, from which the data signals transmitted by the data signal lines can be filtered out and forwarded according to their frequency ranges.

That means that the filter arrangement will be on one

Data signal line simultaneously transmitted data signals, such as voice data and computer data signals, filtered out depending on their specific frequency ranges and forwarded to associated distribution lines, which lead, for example, to a modem device with a subsequent computer network or to a telephone exchange system. This enables data transfer of different data signals between the distribution device and the subscribers connected to it via a common data signal line assigned to the respective subscriber. Different data signal frequencies are assigned to the different data signals, which are detected by the filter arrangement in order to filter out the associated data signals and to be able to pass them on in a targeted manner in accordance with the respective subscriber and the type of data signal (voice data signal or computer data signals).

Although the electronic components of the data signal processing unit can be attached, for example, via separate holders within the receiving device, they are preferably arranged directly on one or more of the functional elements and / or on the receiving device. This is done, for example, by attaching the components directly to wall elements of the receiving device, for example riveted or screwed, or also soldered onto circuit board elements of the functional elements. As a result, a more space-saving and less expensive construction is achieved by the existing ones

Components of the distributor block can be used directly to attach the additional components. This represents a maximally integrative structure.

As an alternative to this, the distributor block can also have one or more cassette elements or plug elements which are detachably assembled with associated functional elements for the mutual transmission of data signals and in which the data signal processing unit or a part thereof is arranged. It is possible to retrofit the distribution block with current data signal processing units by simply replacing the cassette elements or plug elements, without having to replace the distributor as a whole or having to carry out complex and therefore expensive work, such as soldering. The respective cassette element and the associated one

Functional elements are preferably attached to one another via a simple plug connection, which is simultaneously designed as an interface between the cassette element and the functional element.

If cassette elements or plug elements are used as the location of the components of the data signal processing unit in the distribution block, it is particularly preferred to design the respective cassette element or plug element in such a way that it is exchanged for an overvoltage / overcurrent protection magazine or an overvoltage / overcurrent Protective plug and using their interface can be connected to the functional element. Such protective magazines and protective plugs are on various embodiments of main distributors or

Distribution strips provided according to the prior art. Their replacement by the cassette elements or plug elements according to the invention therefore represents a particularly simple and<img file="EP1290901A2_D0002.tif" />

a board attached to the bottom of the receiving trough. This circuit board is also referred to as a backplane and has the advantage that the associated data signal processing unit can be mounted as a part on the receptacle and can be exchanged therefrom, so that the associated distribution device can be assembled and maintained more easily.

Alternatively or additionally, the electronic components of the data signal processing unit or a part number of the

Components arranged on one or more carrier board / s, which is / are detachably assembled with the respectively associated functional element. The carrier board is, for example, attached directly to the rear of the functional element while extending it and is electrically connected to the functional element.

Furthermore, alternatively or additionally, the electronic components of the data signal processing unit or a partial number of the components are on one or more

Intermediate board / s arranged, which is / are each arranged between two functional elements and which is / are provided with a contacting device. The electronic components on the intermediate board are connected to the circuitry of the distribution device via the latter.

If the functional elements are used as sensors of the component (s) of the data signal processing unit, the functional elements advantageously have printed circuit boards which are used to hold the electronic components of the

Data signal processing unit are provided and to which connections for connecting the data signal lines are attached. The printed circuit boards are components with small dimensions and high security with regard to the transmission of electrical signals. They can also be provided as direct carriers of connection parts for the signal lines to be connected, so that a further space saving and a simpler and thus I-¹ »

FIGS. 3 and 4 show an elongated receptacle 13 of a distributor block 3 of a data signal processing system according to an embodiment of the invention in two different perspective views; of the

20th In this case, distributor block 3 is provided as the main distributor. In the receptacle 1 shown in FIGS. 1 and 2, functional elements 14, as are shown, for example, using an example in FIG. 3, are inserted with their longitudinal direction transverse to the longitudinal direction of the

15 Receiving tray 13 inserted one above the other, whereby the distributor block 3 is formed, by means of which the signals from lines connected to the distributor are distributed in a predetermined manner.

10th The receiving trough 13 has a continuously U-shaped

Cross section and thus two mutually parallel side walls as tub legs 15, 16 and a tub floor 17 extending perpendicularly to these tub legs 15, 16, via which the tub legs 15, 16 are connected to one another. The

15 Receiving tray 13 is preferably made of a sheet metal material which is easy to bend and which can also be easily machined by punching. However, the type of production of the recesses formed in the tub is not on μ^» μ-¹ Π o LΠ O LΠ o LΠ

Tub legs 15, 16 are formed and which can also serve as connecting tongues for internal distribution wiring. Between the fixed end of the holding tongues 22 and the trough bottom 17 there is still a narrow leg section 15 ', 16' of the respective trough leg 15, 16 as a recess-free side wall section of the receiving trough

13 provided, which leg section 15 ', 16' forms the foot for the associated holding tongues 22. The respective holding tongue 22 has at its free end section a hole-shaped recess 23 into which a hook 24 of an associated functional element

14 (see FIG. 5) can engage in a latching manner in order to fix the functional element 14 on the receiving trough 13. The respective retaining tongue 22 also has, at its free end section, a recess 25 adjacent to the recess 23, which is provided for receiving a wire guide (not shown) for connecting wires. The recess 25 is hook-shaped for this purpose, so that the wire guide, not shown, can engage with a corresponding counterpart in the recess 25 for fastening it to the retaining tongue 22. The recesses 23 of the retaining tongues 22 of the right and left trough legs 15, 16 in FIGS. 3 and 4 are provided in the longitudinal direction of the receiving trough 13 and are open laterally in opposite directions. The holding tongues 22 of the tub leg 15 on the right in FIGS. 3, 4 are further provided with an end recess 26 on their free end sections, whereas the free end sections of the retaining tongues 22 of the tub leg 16 on the left in FIGS. 3, 4 do not have such a recess. The end-side recesses 26 serve to receive guide lugs (not shown) of the functional elements 14, so that the latter can only be inserted into the receiving trough 13 in the correct orientation when the distributor block is installed.

The holding tongues 22 are also provided at their other end section, ie their foot section, with a recess 27 which is elongated in the longitudinal direction of the tongue. These recesses 27 serve to receive cable connectors (not shown) which are brought laterally to the receiving trough 13 and which are in turn inserted into corresponding receiving sockets on the functional elements 14 for the transmission of data signals. Lines for the connection of the functional elements 14 and / or interconnections via printed circuit boards are provided on these cable connectors.

As can be seen from FIG. 4, the data signal processing unit 18 furthermore has a plug connector part 28 in the form of a plug socket, into which an associated plug connector part (not shown) of one of the functional elements 14 can engage, in order to thus establish an electrical contact between the Functional element 14 and its internal connection as well as its possibly to achieve the present interconnection with other functional elements in a simple manner by inserting this functional element 14 into the receiving trough 13.

The functional element 14 shown in FIG. 5 is provided for receiving copper cables or other stranded cables with a terminal strip 29 with a number of insulation displacement terminals 30, into which the copper cables to be connected (not shown) are inserted. The insulation displacement clamps 30 are arranged in succession in a longitudinal row, one of the hooks 24 described above being located at the respective end of the clamping strip 29. The insulation displacement connectors 30 are continued downwards by contact springs 31, via which a plug contact with a distribution circuit, not shown, is achieved. The functional element 14 also has a second terminal strip, not shown, which is designed in accordance with the terminal strip 29 described above and is arranged parallel to the latter. The signal flow generally runs only separately in the respective functional elements 14, specifically between the lines which are connected to the two cable strips belonging to the functional element 14. However, interconnections between lines that are connected to different functional elements 14 are also conceivable. Furthermore, a functional element can also have more than two cable strips.
