Description

Arrangement for Monitoring Patch Panels at Distributor Points in Data Networks The invention relates to an arrangement for monitoring patch panels at distributor points in data networks, with patch cables, which can be inserted into comsections in the patch panels by means of plugs Data networks serve, inter alia, to provide data links to a larger number of work stations or the staff sitting there, i.e. the users of the data network. The users at the work stations are thus provided with individual services, e.g. with data services or also telecommunication services. In order to achieve this, the data networks have central distributor points, mostly distributor cabinets. Patch panels are provided in the distributor points. These patch panels have ports, i.e. connections. From the ports of these patch panels data cables route data links to the work stations in a star pattern.
There are also active devices located in the distributor cabinets or distributor points besides the patch panels. These active devices serve to distribute the data, telephone signals or other applications.
The connection of the active devices to the patch panels is achieved with patch cables.
These patch cables have a plug at each end. This plug can be inserted into a port or connection on a patch panel. The patch cables are generally 8-wired, flexible and about 0.5 m to 5 m long. In the case of copper cables, the plugs are generally so-called RJ45 plugs, optical fibres have been ready-made with various plugs.
To now supply a work station with the desired services or to make these services available thereto, the active device must be connected accordingly to the corresponding port on the patch panel. If, for example, a user needs a telephone connection as well as a data link, then the telephone system and a data switch system are made available for use by connecting the corresponding ports to the active device.
In the case of changes to services, relocations, transfers or other reorganisation measures, it may become necessary to make changes to these connections at the distributors. In this case, "patch rearrangement" must be conducted. Thus, patch cables must be re-plugged in keeping with the services required from now on.
A series of problems arise as a result of this. A plurality of patch cables cover the individual patch panels and also become entwined with one another. Connections that are no longer required still remain patched in some instances. Thus, the clarity of overview in the case of medium and large installations necessarily decreases drastically in some cases. These problems result in en-ors and time losses in conducting re-patching operations. This in turn leads to an increase in work time for the responsible administrator, as well as for the users, until the services are truly available by reworking. The possibility of damages to the devices or even the completely unintended outage of services as a result of incorrect patching should not be excluded.
Moreover, in companies with dispersed branch offices, it is also desirable to have a remote monitoring and/or control system. In this case, the remote stations should be monitored and possibly controlled centrally through the administrator There is also already a corresponding solution for this on the market. This known solution stores all data, such as names of poets, users etc. for the individual connections in an SQL (structured query language) data bank. This data bank stores its data on a specific computer, which is referred to as the management console.
In order to perform this, further contacts are provided in the ports of the patch panels.
Moreover, an additional wire or an additional connection wire or a conductor is provided in order to create a connection, which can be recognised by a so-called scanner. These scanners are electronic devices. They check a connection from port to port via the conductor. They pass this information to a corresponding management system. The management system is generally implemented on the PC, which also has the data bank.
Retrofits of existing installations prove to be difficult in this case, since special retrofit sets have to be prepared for the already present patch panels. Moreover, there are limitations, since with this system patch cables must always be routed from one patch panel to another patch panel, so that the corresponding readouts can be performed by the scanners. In addition, a respective patch panel must be connected to the active devices, which requires a fixed wiring through connection on the rear or contact side of the patch panel. Patching directly from the active devices to a patch panel cannot be recognised correctly.
Similarly, a patch cable only plugged into a patch panel on one side, in which the second end is open and therefore does not create a correction, can likewise not be recognised.
Moreover, optical fibre patch cables camlot be joined. If necessary, they must be provided with a shielding continuity wire of the above-mentioned comiection wire so that they can be scaimed by the scanners. As a result, they are no longer copper-free and therefore no longer meet the requirements for copper-free optical fibre cabling.
Crosslinks between the distributor cabinets are likewise not permitted, and therefore no second patching systems, which are occasionally desired. These could likewise not be recognised. Finally, the necessary scanning of the current loops formed by the patch cables and the communication of the scanners amongst themselves result in very substantial system running times. If, for example, one takes data networks with a dimension of about a hundred thousand links, which is completely realistic in larger concerns, then these scanning times can also easily amount to 24 hours and more.
Finally, in the case of retrofits the already present patch cables must be completely replaced by new specialised patch cables for this system.
An arrangement with approximately this basic design is proposed in the patent publication EP 0 575 100 B1, for example.
Of similar structure are also systems for tracking plugged in patch cables in a telecommunications distributor system, which are proposed in the patent publication GB 2 347 507 A. Passive sensors are installed on the patch panels of the distributor system and recognise whether a plug is inserted or not. This should render painstaking manual checking umlecessary.

These arrangements also have shortcomings.
Therefore, it is an object of the invention to provide a simpler arrangement for monitoring patch panels at distributor points in data networks, which is above all less costly.
This object is achieved by an arrangement for monitoring patch panels at distributor points in data networks, with patch cables, which can be inserted into connections in the patch panels by means of plugs, wherein both plugs of each patch cable are each fitted with a transponder, with readers with reader coils, wherein each connection in a patch panel is fitted with a reader coil or with a reader, and wherein a data link exists between the readers and an evaluation unit.
Surprisingly, practically all the outlined disadvantages are eliminated as a result of this. Each plug is recognised, as is a cable that is only plugged in on one side.
Connections can be made directly from the active devices to the path panels and are still recognised.
Moreover, the invention enables for the first time the identification of a cable connection between ports of the same design. According to EP 0 575 100 B1 ports can also either only transmit or only receive a signal, and the individual plug of a cable provided there with a means for identification can likewise not manage this.
It is advantageous if the active devices, which can be connected to the patch panels, also have connections, which are fitted with a reader coil or with a reader.
A reader is an electronic circuit known per se, which has a coil in the form of a read coil. This coil has a specific inductivity. The electronic circuit of the reader is able to recognise and evaluate fluctuations in the magnetic field of its coil.
A reader can have several coils. This is also preferably the case for reasons of cost.
The reader can then recognise an evaluation of the fluctuations of the magnetic fields of its different coils by analogous switchover from coil to coil.

It is therefore possible to use a reader for each connection or for each port, this reader then respectively only having one reader coil. However, each connection is preferably provided with one reader coil, but these reader coils are combined and belong to a joint reader, which then feeds several coils, possibly even the entire patch panel, with its corrections.
A transponder also has an electric circuit and a coil. Transponders are known per se or in association with other plug types and application cases from patent publications DE
198 41 738 Al and US-Patent 5,901,776, for example, and are generally very small.
The circuit consists of only a chip and contains no power supply of its own.
The transponder described in US-Patent 5,901,776 is a radio frequency identification transponder (RFID) and is attached to or in a plug, e.g. for a power supply.
An RFID
reader at a coimection can then read this transponder, when it is plugged in.
As a result, the plug can be identified.
The transponder with its transponder coil and electronic circuit is indeed plugged into the connection jointly with the plug. As a result, the magnetic field of the reader or the reader coil engages into the magnetic field of the coil of the transponder or indeed only builds this up and thus at the same time assures the now resulting supply current for the circuit of the transponder. Therefore, an interaction occurs.
Because of the small dimensions of only a few millimetres, the transponder with its components can be integrated without any problem in a patch cable or in a plug of a patch cable or attached there. A transponder is then located at each end of a patch cable adjacent to the plug.
If the transponder is located with its transponder coil in the magnetic field of a reader or a reader coil, then it continuously transmits an identification code. This identification code is recognised by the reader and evaluated. It then passes these data to the evaluation unit, i.e. to a management console.
The management console thus also has the information that a specific patch cable is located in a specific coimection of a specific patch panel. It can evaluate this information as correct or false and inform the user or administrator accordingly.

The control of the circuits of the readers can be organised by microcontrollers. A
microcontroller in this case would control the entire course of the switchover of the coils, the control of the readers, the readout of the data of the reader and also the forwarding of these data to the evaluation unit or to the management console via the data network.
Therefore, there results overall a very reliable and nevertheless very simple method for recognition of the patch cable at the respective comlection of a patch panel.
The evaluation unit or the data bank can hold a series of information. This includes the port assignment of all patch panels in accordance with the question "Is a patch cable plugged in a connection - yes or no?". The infomlation as to which service is made available can also be included, i.e. whether it is a telephone connection, a data link or another connection.
The data bank can also receive information from another source, via changes which have to be made, e.g. because of a change of use of a work station. In this case, the administrator indicates on the PC the evaluation unit which has to be re-plugged, in order to make these changes. An optical display, in particular a light-emitting diode (LED), is preferably arranged at each port or connection on the patch panels.
Any necessary re-plugging can then be identified by an illuminated optical display so that it is recognised in the simplest manner, which of the very many numerous comiections is actually meant at this time. In the case of an error, i.e. an incorrectly plugged cable, the optical display can flash, for example.
These and other errors can be updated in the data bank and serve as a protocol so that any subsequent function failures can be checked.
Optical fibre cables can be used as they are, i.e. as pure optical fibre cables without a copper shielding continuity wire.
The system is extremely quick in its processing time. Crosslinks between the distributor cabinets are permitted and are also recognised.

The necessary components are all very inexpensive, both the readers, transponders and the microcontrollers, and only increase the production costs slightly.
Scanners are no longer required.
The system can also be added to. The coils for the readers can be attached to the ports by a cover. The coils are displaceable, the cover plates are usable for different patch panels. As a result, only a few cover plates are to be fully scanned in keeping with the numbers of ports used.
An embodiment of the invention shall be described in detail below.
Figure 1 is a schematic representation of an arrangement according to the invention.
Figure 1 schematically shows a preferred embodiment of such an arrangement according to the invention, Visible is a patch panel 10 with a plurality of connections 1 l, the so-called ports. These connections allow patch cables 20 or plugs 21 located at the end of a patch cable 20 to be inserted.
The patch panel 10 is fitted with one or more readers 12. Each reader 12 has one or more reader coils 13. Each connection 11 is fitted with a reader coil 13.
Moreover, each connection 11 also has an optical display 14, e.g. in the form of a light-emitting diode.
The patch cables 20 serve to supply the patch panels amongst themselves or with specific service devices such as telephone corrections. A patch cable 20 therefore has two ends, each of which is fitted with a plug 21. A transponder 22 is located in the plug 21 or, where fitted subsequently, on the plug 21 of the patch cable 20.
The transponder 22 has a coil as well as an electronic circuit, but is kept very small overall and has sufficient space on or in the plug 21 without any problem. On original manufacture the transponder 22 would be injection moulded with the plug 21 or in the plastic around the plug 21, hut in the case of retrofit it can be attached to the outside without any problem.

g After insertion of the plug 21 into the connection 11 of a patch panel 10, the transponder 22 is therefore located with its coil in direct vicinity of a reader coil 13, so that the magnetic fields of the two coils influence one another or build up. The change in the magnetic field of the reader coil 13 through the coil of the transponder 22 can be evaluated by the reader and forwarded accordingly.
This forwarding is performed at an evaluation unit 30, possibly with a microcontroller interposed.
The evaluation unit 30 can stand at another, possibly also far removed, location to allow remote monitoring.
For the subsequent fitting of already existing patch panels 10 it is advantageous if a cover plate 15 is provided that supports the readers 12 and reader coils 13.
This cover plate 15 can than be simply placed in front of the patch panels 10 with their connections 11; so that the readers 12 and the reader coils 13 are automatically positioned in the vicinity of the connections 11.
