Abstract

Information is sent by a DSL system component using a non-disruptive operational data parameter. One or more bits of the non-disruptive operational data parameter are used to send other information. In some instances the selected parameter will be an unused parameter, such as an unused fast operational mode or interleaved operational mode parameter used to report operational data in a DSL system. In one embodiment of the invention, a remote modem provides a unique equipment identifier that can be paired with the telephone number on which the modem is operating. Verification of and/or searching for the correct pairing of telephone number and unique equipment identifier can be performed as well.

Claims

1. A method comprising:

obtaining, at a DSL (Digital Subscriber Line) system component, information to be sent to a recipient;

determining whether a DSL system component is operating in a fast operational mode or an interleaved operational mode and selecting the other mode as an unused mode;

selecting a system management operational data parameter of the unused mode from among a plurality of system management operational data parameters used to communicate management operational data on a physical layer management channel;

assigning the information, at the DSL system component, to at least one bit of the selected operational data parameter in place of the information that the parameter normally would carry to generate an amended operational data parameter, the parameter being amended by containing the information assigned to the parameter;

sending the amended operational data parameter using the physical layer management channel from the DSL system component to the recipient.

2. The method of claim 1 wherein the DSL system component is one of the following:

a modem;

an ATU-C (Asymmetric Digital Subscriber Line Transceiver Unit-Central);

or an ATU-R (Asymmetric Digital Subscriber Line Transceiver Unit-Remote).

3. The method of claim 1 wherein the unused mode operational data parameter is an operational data parameter from which one or more bits can be requisitioned without disrupting normal operation of the DSL system.

4. The method of claim 1 wherein the information to be sent is at least one of the following:

a telephone number;

a UEI (Unique Equipment Identifier);

a serial number;

channel insertion loss information;

or a number assigned by a controller in another command to the DSL system component.

5. The method of claim 1 wherein sending the amended operational data parameter to a recipient comprises sending the amended operational data parameter to a controller.

6. The method of claim 5 wherein the controller is a DSM (Dynamic Spectrum Management) Center.

7. The method of claim 6 wherein the amended operational data parameter is sent to the controller via a DSL system MIB (Management Information Base).

8. The method of claim 1 wherein assigning the information comprises assigning portions of the information to consecutive operational data parameters so that the information is sent using more than one consecutive operational data parameter and wherein sending comprises sending the more than one consecutive operational data parameters.

9. A controller for a DSL (Digital Subscriber Line) system, the controller comprising:

means for instructing a DSL system component to transmit information to the controller using a system management operational data parameter of a physical layer management channel, wherein the component uses one or more physical layer operational data parameters of a DSL operational mode of the DSL system to report operational data over the physical layer management channel and wherein instructing the component to transmit information includes instructing the component to determine whether the DSL system component is operating in a fast operational mode or an interleaved operational mode and select the other mode as an unused mode, to identify an operational data parameter from the unused DSL operational mode and to assign at least part of the information to one or more bits of the identified operational data parameter in place of the information that the parameter normally would carry to generate an amended unused operational data parameter, the parameter being amended by containing the information assigned to the parameter;

means for collecting the amended operational data parameter sent by the DSL system component using the physical layer management channel and for retrieving the transmitted information therefrom.

10. The controller of claim 9 further comprising means for verifying the information transmitted by the component by comparing the transmitted information to expected information.

11. The controller of claim 10 further comprising a search module for searching for correct information when the information transmitted by the component does not match the expected information.

12. The controller of claim 9 wherein the controller is a DSM (Dynamic Spectrum Management) Center.

13. The controller of claim 9 wherein the controller is a computer system.

14. The controller of claim 9 wherein the component is a DSL modem.

15. The controller of claim 14 wherein the DSL modem is either an ATU-R (Asymmetric Digital Subscriber Line Transceiver Unit-Remote) modem or an ATU-C (Asymmetric Digital Subscriber Line Transceiver Unit-Central) modem.

16. The controller of claim 9 wherein the information transmitted by the component is a unique equipment identifier.

17. The controller of claim 9 wherein the component transmits the information to a DSL system MIB (Management Information Base) and further wherein the controller collects the information from the MIB.

18. A machine-readable medium having stored thereon instructions that, when executed by a processor, cause the processor to perform operations comprising:

obtaining information to be sent to a recipient;

determining whether a DSL system component is operating in a fast operational mode or an interleaved operational mode and selecting the other mode as an unused mode;

selecting a system management operational data parameter of the unused mode from among a plurality of system management operational data parameters used to communicate management operational data on a physical layer management channel;

assigning the information, at the DSL system component, to the selected operational data parameter in place of the information that the parameter normally would carry generate an amended unused operational data parameter, the parameter being amended by containing the information assigned to the parameter;

sending the amended operational data parameter using the physical layer management channel from the DSL system component to the recipient.

19. The medium of claim 18 wherein the unused mode operational data parameter is an operational data parameter from which one or more bits can be requisitioned without disrupting normal operation of the DSL system.

20. The medium of claim 18 wherein sending the amended operational data parameter comprises sending the amended operational data parameter to a controller.

21. A controller for a DSL (Digital Subscriber Line) system, the controller comprising:

an information verification module to instruct a DSL system component to transmit information using a physical layer management channel to the controller using a physical layer operational data parameter as an amended operational data parameter, the physical layer management channel having a plurality of system management operational data parameters used to communicate management operational data on the channel, some of the parameters being used in a fast operational mode, some being used in an interleaved operational mode, and some being used in both operational modes, the operational data parameter for transmitting the information being selected as an operational data parameter of a currently unused operational mode of the DSL system component, the parameter being amended by assigning the information to be transmitted to the parameter in place of the information that the parameter normally would carry if the DSL component were using the unused operational mode; and

a collecting module to collect the amended operational data parameter sent by the DSL system component using the physical layer management channel and to retrieve the transmitted information therefrom.

22. The controller of claim 21 wherein the information verification module comprises means for verifying the information transmitted by the component by comparing the transmitted information to expected information.

23. The controller of claim 21 further comprising a search module to search for correct information when the collected amended operational data parameter does not match expected information.

24. The controller of claim 21 wherein the information transmitted by the component is a unique equipment identifier.
