Definitions
- the invention relates to a method and a device for testing xDSL line cards, preferably in the installed state, the line cards having at least one chipset which can be operated with the same bandwidth both in the upstream direction and in the downstream direction, and the line cards each have at least one, preferably sixteen, line ports.
- xDSL line cards in particular ADSL line cards
- ADSL line cards are generally known.
- connections between an end user and the port of a line card cannot be established. In such a case, it is necessary to find the cause of the error.
- a possible problem for a non-functioning structure can be a faulty line card.
- the modems of the subscribers of an ADSL connection are suitable for transmission rates in the direction of the office with 896 kbit / s and coming from the office with up to 8.192 Mbit / s, while line cards on the office side data arriving from the subscriber with up to 896 kbit / s understand and can transmit to the subscriber with up to 8.192 Mbit / s.
- the inventors propose to improve the method for testing office-side xDSL line cards in a line card carrier with at least two line cards, with at least one line card having at least one chipset, which has both in the upstream direction and in the downstream direction same bandwidth can be operated and the line cards each have at least one, preferably sixteen, line ports.
- the improvement of the method according to the invention now consists in that an electrical connection between a line port to be tested and a further line port to be tested, which can be operated in the upstream and downstream directions with the same bandwidth, is established via a test bus, the testing line port loaded with software that simulates a subscriber modem becomes.
- the line port to be tested is then defined as error-free if a successful connection has been established between the line ports and this has given a function confirmation for the line port to be tested.
- both the line port to be tested and the line port to be tested are located in different line cards and on the same line cards.
- the first situation with the line port to be tested and the line port to be tested on different line cards is always necessary if the line port to be tested is located on a line card with old conventional chipsets that provide a lower bandwidth for your upstream card than for the downstream side. If several chipsets are used on a card, all of which have the option of operating both the downstream and the upstream sides with the same width, then a port can be connected to a first chipset and a port to a second chipset a kind of self-test for this line card can be generated on the same line card.
- this method states that a line connection of at least one line port to be tested of a first chipset, each with a further line line of another chipset to be tested, which can be operated in the upstream and downstream directions with the same bandwidth, is established on the same line card the test line port is loaded with software that simulates a subscriber-side modem and, as a successful connection, represents a function confirmation for the line port to be tested.
- This type of method makes it possible, for example, to test line cards at the end of a production process, for example by using a corresponding connector that generates a test bus and connects the individual ports of different chipsets with one another, so that in each case one chipset connects the ports of the other Can test chipset.
- the inventors also propose a line card carrier with a multiplicity of xDSL line cards, each with at least one, preferably sixteen, line ports, which is improved in that a test bus and a controller are provided, which optionally select the line Connect the ports of the line cards to each other and at the same time disconnect their respective connection to the subscriber side for test purposes.
- the inventors also propose a test coupling plug for connection to an xDSL line card with at least two independent chipsets, for operating the line card with high bandwidth both in downstream and in upstream direction, which is characterized in that at least one port of a chipset is connected to a port of another chipset.
- a chipset it is now possible to configure line cards in the non-installed state, that is to say, for example, at the end of the manufacturing process, by plugging in such a coupling test connector, so that the ports of one chipset are connected to the ports of the other chipset.
- the first chipset is operated with the software as used in the office-side operation, while the other chipset contains software that simulates a subscriber-side modem, so that a connection can be established between the ports of the individual chipsets. If such a connection is set up positively, the functionality of the individual ports is verified.
- Figure 1 State of the art regarding the testing of line cards on the office side
- Figure 2 Establishing a connection between a line card to be tested in a line card carrier
- Figure 3 Establishing a connection between two ports of different chipsets on the same line card in a line card carrier
- FIG. 4 test coupling plug according to the invention
- Figure 5 Structure of an ADSL line card with two IVAX chipsets for eight ports each.
- FIG. 1 shows a schematic representation of a line card carrier 1 on the official side of an ADSL connection.
- the line card carrier 1 has a line card 2 which has sixteen line ports.
- the line port 1 is connected to an end user 4 via a two-wire line 8. If there is no active data communication despite this physical connection to the end user 4, the line card 2 on the office side in the line card carrier 1, at least with regard to its port 1, must be checked. For this purpose, the physical connection to the subscriber 4 is disconnected with the aid of a relay 7 and instead a physical connection via the test bus 6 to a test device 5 to be connected is established.
- This test device is not located on the line carrier 1, but is a specially developed piece of equipment that is connected to the test bus 6 of the desired line card carrier 1 if required.
- the control of the line cards 2 in the line card carrier 1 takes place via a control unit 3, which creates the connection to the desired line port and the test device via appropriate switching of circuit matrices.
- At least one line card 9 is used in a line card carrier 1, which has at least one line port - here line line number 1 shown - connected to the test bus 6, so that With the help of the control device 3 for testing the line port 1 on the line card 2, a direct connection between the line ports 1 of the two cards 2 and 9 is established, while at the same time care is taken via the control unit 3 that the chipset of the line card 9 with a Software is supplied which enables the line card 9 to simulate a subscriber-side modem. As a result, a data connection can now be established between port 1 of line card 9 and port 1 of line card 2.
- line port 1 is the line card te 2 functional and the error found must either be searched on the two-wire line 8 to subscriber 4 or at subscriber 4 itself. If the connection between line card 9 and line card 2 is not established, the fault must be found on line card 2 so that it must either be replaced or repaired.
- the line card 9 has two chipsets, each of which operates a first part 9.1 of the line ports 1 to 8 or a second part 9.2 of the line ports 9 to 16.
- the line card 9 can also check other line cards on the same line card carrier by corresponding connection to the test bus 6.
- FIG. 4 shows an example of the design of a test coupling connector for a line card 9 with two chipsets, which line card 9 in two independent areas Split 9.1 and 9.2.
- the test coupling connector 14 is designed such that the first eight line ports 1 to 8, which belong to the first chipset, are each connected to one line port of the second part of the line card, so that the connection is established between the lines assigned to each other -Ports the functionality of the corresponding ports can be checked.
- FIG. 5 shows the ADSL line card 9, which has two so-called IVAX chipsets 10.1 and 10.2, which are controlled by a controller 11. Both chipsets can be loaded with different software, so that the associated line ports 1 to 8 or 9 to 16 either meet the requirements of an office modem - this is the standard situation - or the requirements of a subscriber modem - for test purposes.
- This makes it possible with the aid of appropriate coupling of the line ports to one another either to carry out self-tests with respect to the line ports within a line card or, if a connection is established with other line ports, to test further line ports within the same line card carrier.
