Bonded DSL Shared Channel for Peak Data Rate Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems using DSL over copper facilities face limitations in data rate due to copper length, while DOCSIS systems offer higher peak rates but with shared channels that result in lower average rates for customers, making them less competitive.
Innovation Solution
Implementing a communication system with high-speed optical fiber links between a central office and intermediate points, using bonded DSL links to create a shared data channel that allocates peak data rates among active customers, ensuring each customer benefits from idle customers' bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If DOCSIS systems use shared coaxial cable channels, then peak data rates are improved, but average data rates deteriorate as more customers become active
Solution Approach 1:
The system dynamically allocates bandwidth from idle customers to active customers in real-time. When some customers are not actively communicating, their allocated bandwidth is automatically redistributed to customers who need it, allowing the system to maintain high peak data rates while improving average data rates through adaptive resource management.
Solution Approach 2:
The system changes the operational parameters of the shared channel by implementing dynamic bandwidth allocation mechanisms. Instead of fixed bandwidth assignments, the system adjusts bandwidth parameters in real-time based on customer activity levels, enabling the channel to provide both high peak rates and improved average rates through parameter optimization.
2Device complexity
If DSL systems use copper facilities, then infrastructure simplicity is maintained, but data rates deteriorate as copper length increases
Solution Approach 1:
The system segments the copper facility into multiple shorter bonded channels, each with its own transceivers. By dividing the long copper connection into multiple shorter segments that are bonded together, the system maintains infrastructure simplicity while achieving high data rates that would otherwise require much shorter copper lengths.
Solution Approach 2:
The system merges multiple bonded DSL channels into a single high-capacity communication path. By combining multiple shorter copper channels through bonding technology, the system achieves data rates comparable to much shorter single channels while maintaining the simplicity of using existing copper infrastructure.
3Speed
If copper pair length is shortened to increase data rates, then data rates are improved, but infrastructure complexity increases with additional intermediate points
Solution Approach 1:
The system merges multiple intermediate points into a coordinated bonding group, where transceivers at different locations work together as a unified high-capacity channel. This approach maintains the infrastructure of multiple intermediate points while achieving high data rates through the combined capacity of all transceivers in the bonding group.

AI summary
The present disclosure generally pertains to systems and methods for communicating data. In one exemplary embodiment, a system has a high-speed channel, such as an optical fiber, between a network facility, such as a central office (CO), and a first intermediate point between the network facility and a plurality of customer premises (CP). Digital communication links, such as DSL links, are used to carry data between the first intermediate point, such as a feeder distribution interface (FDI), and a second intermediate point, such as the Distribution Point (DP). Non-shared links may then carry the data from the second intermediate point to the CPs. The links between the two intermediate points are bonded to create a high-speed, shared data channel that permits peak data rates much greater than what would be achievable without bonding. In some embodiments, multicast data flows may be prioritized and transmitted across a set of connections to each of the intermediate points. In addition, it is possible to power components at the intermediate points from one or more of the CPs.
