DSL system
Methods, techniques, computer program products, apparatus, devices, etc., used in connection with DSL Management Interfaces, significantly improve the management capabilities of a DSL network and/or improve testing relating to DSL equipment and services by permitting better control and operation of a DSL system, including implementation of timestamping for more accurate measurement, monitoring and control of a system. Timestamping further allows customized data collection techniques, where a DSL line can be measured or monitored at intervals whose frequency depends on the line's stability. Moreover, data parameter read and control parameter write operations are presented in conjunction with the use of timestamping. Also, control and operation of a DSL system is enhanced by implementing bit-loading that minimizes, eliminates or otherwise mitigates the amount by which the SNR margin per tone exceeds a maximum SNR margin quantity, where such bit-loading can be selected through an appropriate interface.
1. A method of operating a DSL system, the method comprising:
using a communication between two or more components in a DSL system to associate an operational parameter with a timestamp that defines an event that is associated with at least a phase among a plurality of phases that identifies an operational mode of the DSL system, the operational mode comprising at least one of diagnostics or normal initialization;
appending the timestamp after the operational parameter; and
using the operational parameter in operating the DSL system.
2. The method of claim 1 wherein the time stamp comprises a time reference that comprises a point in time defined by at least one of the following: absolute time; relative to one or more phase transitions; or relative to one or more phase-defined events.
3. The method of claim 1 wherein the operational parameter is a control parameter used in an update operation of the DSL system.
4. The method of claim 3 wherein the timestamp comprises at least one of the following: information regarding whether the update operation will force initialization; information regarding when the update operation will be enforced and/or implemented; or information regarding any delay between a known time reference and the enforcement and/or implementation of the update operation.
5. The method of claim 1 wherein appending the operational parameter comprises associating the timestamp with a name for the operational parameter and a value for the operational parameter.
6. The method of claim 1 further comprising: grouping a plurality of operational parameters; and appending the timestamp to the plurality of operational parameters.
7. The method of claim 1 further comprising: defining a plurality of time markers; wherein appending the timestamp to the operational parameter comprises associating one of the plurality of time markers to the operational parameter.
8. The method of claim 1 wherein the timestamp is associated with a name and a value of the operational parameter.
9. The method of claim 1 wherein the two or more components have a common time reference.
10. The method of claim 1 further comprising using the timestamp to synchronize the communication between the two or more components.
11. The method of claim 1 wherein the two or more components, in periodical intervals, exchange a message comprising the time stamp.
12. The method of claim 1 wherein the two or more components communicate with a delay that does not affect an accuracy of the timestamp.
13. The method of claim 1 wherein the timestamp is based on a synchronizing event between the two or more components in the DSL system.
14. The method of claim 1 further comprising using two timestamps to obtain a duration of the event.
15. The method of claim 1 further comprising the timestamp to obtain a time between two events.
16. The method of claim 1 wherein the timestamp is indicative of a time of measurement of the operational parameter.
