DSL CPE Management Center for Line Stability and Data Rate Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DSL management systems face limitations in diagnosing and enhancing line performance due to lack of insight into end-user experiences, limited bandwidth for control communication channels, exposure to impairments like noise and interference, and restrictions in DSLAM parameter settings, which can lead to suboptimal DSL connection performance.
Innovation Solution
A Customer Premises Equipment (CPE) Management Center (CMC) is introduced to manage lines end-user-centrically, collecting operational data, providing diagnostics, and automatically modifying CPE device operations to enhance line performance, even where DSLAM management interfaces are not directly accessible, thereby addressing line problems and improving stability and data rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If line management is performed at the CO side via DSLAMs, then infrastructure control and integrity are maintained, but access to equipment for service quality management is restricted and limited
Solution Approach 1:
A CPE-side management system acts as an intermediary between the CO infrastructure and the end-user services. This intermediary collects operational data from CPE devices and provides diagnostic capabilities without requiring direct access to CO equipment, thus maintaining infrastructure integrity while enabling service quality management.
2Loss of energy
If control communication channel bandwidth is limited, then network resource consumption is reduced, but information exchange between customer devices and service provider equipment is insufficient
Solution Approach 1:
The patent extracts and processes operational data locally at the CPE side before transmitting it to the service provider. By performing data collection, processing, and preliminary analysis at the edge (CPE devices), the system reduces the amount of raw data that needs to be transmitted over the limited bandwidth communication channel, thus conserving network resources while still providing necessary diagnostic information.
3Reliability
If active line management is implemented, then service quality monitoring improves, but cost of maintaining a great number of lines increases
Solution Approach 1:
The system enables self-service line management by automatically collecting operational data from CPE devices and performing diagnostics without requiring manual intervention. The automated data collection and analysis capabilities allow the system to monitor service quality across numerous lines independently, reducing the need for expensive manual maintenance while improving service quality visibility.
4Stability of the object's composition
If DSLAM parameter settings are restricted, then infrastructure stability is maintained, but provisioning and optimization of DSL connections is prevented
Solution Approach 1:
The patent introduces dynamic parameter adjustment capabilities at the CPE side, allowing operational parameters to be modified based on real-time conditions and diagnostic results. This dynamic approach enables provisioning and optimization of DSL connections without requiring changes to the fixed DSLAM infrastructure settings, thus maintaining infrastructure stability while providing adaptability for service optimization.
Data Source
AI summary
Described are systems and methods for a Digital Subscriber Line (DSL) customer premises equipment (CPE) Management Center (CMC). In one embodiment, the CMC includes a communications interface to receive information from the CPE device regarding operation of the CPE device. The received information is analyzed and a command signal generation module generates a corresponding command signal for transmission to the at least one CPE device to modify the CPE device operation based on the analysis results in a manner which either enhances CPE device performance, for example increasing data rate, or improves line stability, for example reducing CPE error rate.
