Abstract

A method for double-ended line qualification and monitoring of xDSL links employs a single test program which is sent by a first subscriber at one end of the xDSL link to a second subscriber at the other end of the xDSL link. Line qualification and/or monitoring is carried out by processing this test program and sending the test results obtained in this step back to the first subscriber. The line qualification and/or monitoring is triggered after the code of the test program has been transmitted by the first subscriber. In this method, the first subscriber represents a modem at the switching end and the second subscriber represents a modem at the subscriber end. The test program is a program module which is connected to other program modules via a message queue.

Claims

1. A method for double-ended line qualification and monitoring of xDSL links, comprising:

transmitting a test program from a first subscriber at one end of the xDSL link to a second subscriber at the other end of the xDSL link,

execution of the line qualification and/or monitoring by this second subscriber by processing this test program and

sending the test results already obtained back to the first subscriber.

2. The method as claimed in claim 1, wherein the line qualification and/or monitoring is triggered after the code of the test program has been transmitted by the first subscriber.

3. The method as claimed in claim 1, wherein the first subscriber represents a modem at the switching end.

4. The method as claimed in claim 1, wherein the second subscriber represents a modem at the subscriber end.

5. The method as claimed in claim 1, wherein the test program represents a program module which is connected to other program modules via a message queue.

6. The method as claimed in claim 1, wherein the test program is used both for diagnostic and for real-time interpretation of the xDSL link.

7. The method as claimed in claim 1, wherein a line qualification and/or monitoring can also be carried out at the end of the first subscriber by processing this test program.

8. The method as claimed in claim 1, wherein the xDSL link can be an ADSL, a UDSL or an SDSL link.

9. A method for double-ended line qualification and monitoring of xDSL links comprising:

activating a text program of a second subscriber at one end of the xDSL link from a first subscriber by a command which causes the second subscriber to generate signals which are suitable for testing the line,

execution of the line qualification and/or monitoring by the second subscriber by processing the test program of the second subscriber, and

sending the test results obtained back to the first subscriber.

10. The method as claimed in claim 9, wherein the signals generated by the second subscriber are the signals which are generated during the training of the xDSL link.

11. The method as claimed in claim 9, wherein the data necessary for line qualification and monitoring are read out of a memory of the modem at the subscriber end or modem at the switching end, which contains a multiplicity of data which characterize the upstream and downstream data link, respectively.
