Integrated Signal Splitter for DSL POTS Surge Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surge protection modules are not suitable for providing high-speed digital subscriber line (DSL) services due to noise interference from external sources, which affects the quality of DSL service.
Innovation Solution
A modified surge protection module is designed with an integrated signal splitter that combines DSL and POTS signals, reducing noise interference by using high-speed twist wires and rerouting electrical connections to cancel electromagnetic interference (EMI).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional surge protection module is used, then overvoltage protection is provided, but noise interference from external sources affects DSL service quality
Solution Approach 1:
The patent divides the signal transmission path into separate channels: a first channel for POTS signals and a second channel for DSL signals. The splitter component separates these signals, allowing each to travel through dedicated paths that reduce cross-interference and noise from external sources, thereby improving DSL service quality while maintaining protection functionality.
Solution Approach 2:
The patent introduces a splitter component as an intermediary device between the external lines and the internal circuitry. This splitter acts as a mediator that combines POTS and DSL signals while isolating them from external noise sources, enabling both signal types to coexist without interfering with each other or with the surge protection mechanisms.
2Reliability
If an integrated signal splitter is added to reduce noise, then DSL service quality improves, but device complexity increases
Solution Approach 1:
The patent merges the splitter functionality directly into the surge protection module housing, integrating multiple functions (surge protection, signal splitting, and signal combining) into a single unified device. This consolidation reduces the need for separate external components, thereby managing device complexity while achieving noise reduction and improved DSL service quality.
Solution Approach 2:
The surge protection module is designed with multi-functionality, serving both as a surge protection device and as a signal splitter/combiner. The same housing and structural elements support both protection operations and signal separation, eliminating the need for dedicated separate components and thus controlling overall device complexity while providing enhanced DSL service quality.

AI summary
The disclosed embodiments include a surge protection module that includes an integrated signal splitter configured to combine a signal from a DSL tip wire with a signal from the POTS tip pin to generate a DSL/POTS tip output signal, and combine a signal from a DSL ring wire with a signal from the POTS ring pin to generate a DSL/POTS ring output signal. The integrated signal splitter is configured to be in electrical communication with an overvoltage protection component and to output the DSL/POTS tip output signal and the DSL/POTS ring output signal to the overvoltage protection component.
