Definitions
- the present invention relates to a method and a device for connecting equipment into a telephone line. More specifically, to a method and a device for being able to connect new equipment into a telephone exchange without resulting in interruption of existing service in the telephone exchange, and without the need for any rewiring of cross-connect wires between the plints.
- ADSL Asymmetric Digital Subscriber Line
- DSL digital subscriber line
- the object of the invention is to solve the problem with manual connection of new services into the cross-connect of a telephone exchange, without interrupting an already existing service on the telephone line.
- Another problem that is solved by the invention is to minimize the need for rewiring or installing new cables between plints in the cross-connect, and to minimize the need for new plints in the cross- connect.
- the invention enables that the telephone line to be remotefy controlled in that it can be reconnected to different services and that the existing service is reconnected to another telephone line.
- the invention also enables connection of the equipment without having to input cross-connect data from a database. Instead the device must only take care of the changes that are made after the connection. This can also be performed to minimize the size of the selector stages comprised in the automatic cross-connect.
- Fig 1 shows the principle for connecting a telephone line in a cross-connect.
- Fig 2 shows the principle for connecting printed circuit boards in the cross-connect plints.
- Fig 3 shows the principle for manual connection in the cross-connect dependent on different needs.
- Fig 4 shows the principle for cross-connecting in the case of hired connections.
- Fig 5 shows the principle for connecting new services into the cross-connect in accordance with prior art.
- Fig 6 shows an alternative connection similar to that of fig 5.
- Fig 7a and 7b shows the principle for connecting new services in accordance with the invention.
- Fig 8 shows an alternative design of the connection board in accordance with the invention.
- Fig 9 shows the connection board in accordance with fig 8 connected to further selector stages.
- Fig 10 shows an alternative design of the connector card.
- Fig 11 shows the principle for how the connector card according to the invention can be used in new installations.
- FIG. 1 For the sake of simplicity, the drawings show only one telephone wire of a pair of wires that make up a telephone line, wherein a cross-connect plint normally comprises 8 or 10 pairs i.e. a total 16 or 20 wires. In the following description one wire will represent such a pair.
- PSTN och ADSL normal telephone service
- PSTN och ADSL normal telephone service
- the invention is however not limited to these services and other DSL technologies can also be applicable, i.e. be connected by means of the invention.
- the cross-connect 1 comprises two cross-connect plints, one plint 10 on the station side or exchange side and one plint 20 on the line side. From the exchange a wire 11 leads to the plint 10 and from the plint 20 an outgoing wire 21 leads to the subscriber. Between the plints 10 and 20 there is a cross-connect wire 30 or so- called jumper wire, that connects the station side with the line side. These jumpers are installed manually to make the cross-connect and are installed or removed as required for connecting or disconnecting the service.
- Fig. 1 there is shown an interruption mechanism in the cross-connect plints on the line side as well as on the station side.
- the interrupt functionality is present only at the station side in some cases and only at the line side in other cases. This does not affect the invention and its principles can be used in all these cases.
- the cross-connect plints are designed such that e.g. a printed circuit board (PCB) can be inserted into them to make contact with the line side as well as with the station side.
- PCB printed circuit board
- the invention utilizes this possibility and connects line side and station side by means of, for example, a printed circuit board 40 in accordance with Fig 2.
- the cross-connect wires are installed for connecting service as required by the operator or service provider in accordance with Fig 3.
- a first operator offers two different services via the connection plints 10a and 10b, respectively, while a second operator offers another service via the connect plint 10c.
- the subscriber that is connected to the plint 20 is dependent on the circumstances connected to any of the offered services via the connect wire 30a, 30b or 30c.
- the wire pairs on the line side can also be subleased as a so-called hired connection wherein cross-connection is carried out in accordance with Fig 4. Approximately 10 to 20 % of the wire pairs are handled in this way. In these cases, it is possible that a large number of reconnections per unit of time may occur.
- a reconnection must be made in the cross-connect, which increases the number of cross-connect plints.
- the original connection wire 30a between the connect plint 10a of the station side and the corresponding plint 20a of the line side, must be removed and new connection wires 30b and 30c are connected to a new plint 10b on the station side and to new plint 20b on the line side, respectively.
- new connection wires 10b and 20b new wires have to be connected to a filter 50, which in turn is coupled to a modem 60.
- Fig. 6 shows reconnection to a new type of service and connection of the vacant position in the cross-connect to a new line.
- new connect wires 30b and 30c must be connected to new plints 10b for the new service and to 20b to the new line, respectively, while the original connection wire 30a was removed.
- a new wire 1 la has to be connected to the equipment for providing the new DSL service, for example a modem 60.
- connection card 70 in accordance with the invention is used.
- the connection card 70 comprises a unique non-interrupt mechanism or a bypass connection mechanism 80 in accordance with Fig. 7a and 7b.
- Fig. 7b shows the connection into both subscriber and station sides of the cross-connect.
- the other figures show the connection of the connection card 70 only into one side, but Fig. 7b is applicable also on the other figures.
- the non-interrupt mechanism permits connection of the device without any interruption in existing services.
- the non-interrupt mechanism can be made externally, in which case will require additional wiring on the jumper - side of the cross-connect plints .
- connection card 70 is normally connected to the plints of the station side as well as to the plints of the line side in accordance with Fig 7b. There is however nothing that prevents a connection to be made, for example, to the station side. In the latter case access is only achieved to preexisting connected lines and new lines must be manually connected. This also means that the possibility to connect measurement equipment on unused pairs is wasted, depriving us of the ability to sublease the lines. The possibility to connect measurement equipment is important in order to maintain the quality of the subscriber lines when introducing new DSL technology.
- the connect card 70 comprises, in addition to the previously mentioned interrupt mechanism and bypass connection mechanism 80, one or a number of selector mechanisms associated with the jumper side and/or the contacts of the station side and/or the line side in the cross-connect plint 10 in accordance with Fig 8. These selector mechanisms can of course be shared between the cross-connect plints of the station side and the line side, respectively.
- the outputs 90 from the connection card 70 can be utilized in different way according to the current need. If full cross-connect capacity is required, the selector stages are connected to further connector stages 100 in accordance with Fig 9. The outputs can also be connected to outputs 90 of other connect cards to either a pool of filters or modems or linked them to further selector stages in accordance with Fig. 10. These filters and modems are preferably distributed over the connection cards whereby no external wiring is needed.
- the device in accordance with the description achieves that when the expected number of reconnections in a certain group are wired out to more centrally positioned selector stages.
- the inclusion of the filter pool in the device in accordance with Fig. 10 minimizes the need for wiring.
- cross-connections can be carried out between a large number of wires and/or pieces of service equipment due to the fact that certain of the outputs of the selectors can be connected to other groups via more central selector stage.
- the device can be dimensioned such that only the predicted number of reconnected lines must be wired out from these grouped selector modules.
- connection cards are designed such that reconnection is possible when the cards are installed.
- the filters and/or the modems can be placed either on the access cards or in the center stage of the automated cross-connect equipment.
- the line side and the station side can be connected to the same block in accordance with Fig. 11, thereby using half the number of cross-connect plints and thus corresponding floor space.
