Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital subscriber line (DSL) technologies are not suitable for all communication systems due to high equipment and implementation costs, restrictive wiring requirements, and limited integration with existing facilities, making them inefficient for data transfer during telephone calls.
Innovation Solution
A protocol utilizing Phase Locked Loops (PLLs) for clock management, allowing data transmission over existing telephone lines without the need for additional DSL equipment, by packaging data bytes and using NRZI data packaging, which eliminates the requirement for multiple discrete timing devices and enables flexible bandwidth allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If DSL technologies are used for high-speed data transfer, then data transfer speed is improved, but equipment cost and system complexity increase
Solution Approach 1:
The patent combines voice and data transmission into a single telephone line interface, eliminating the need for separate DSL equipment. The system merges multiple data streams (voice, fax, data) into one communication channel, using a single integrated protocol handler to process all transmissions, thereby reducing equipment complexity while maintaining high-speed data transfer capability
Solution Approach 2:
The telephone line interface is designed to handle multiple functions universally - voice calls, fax transmissions, and high-speed data transfer all through the same interface and protocol. This multi-functional design eliminates the need for specialized DSL modems and equipment, allowing existing telephone infrastructure to serve multiple purposes efficiently
2Speed
If DSL technologies are deployed, then data transfer capability is improved, but integration with existing facilities becomes more difficult
Solution Approach 1:
The system uses existing telephone line infrastructure to provide high-speed data transfer without requiring external DSL equipment or modifications to the telephone company's network. The protocol handler at the user end automatically manages the transmission, encoding and decoding data using the existing voice-grade lines, making the system self-sufficient and easily integrable into any existing telephone facility
Solution Approach 2:
The patent creates a software-based protocol handler that replicates the functionality of hardware DSL modems. By copying the essential data transmission and encoding functions into software that runs on existing telephone equipment, the system achieves high-speed data transfer capability without requiring physical DSL modems or modifications to the telephone network infrastructure
3Speed
If separate data lines are used for high-speed transfer, then data transfer speed is improved, but system overhead and cost increase
Solution Approach 1:
The patent merges voice and data transmissions into a single telephone line interface, eliminating the need for separate data lines. The protocol handler combines multiple data streams (voice, fax, data) into one communication channel, using shared encoding and decoding functions, thereby reducing system overhead and equipment requirements while maintaining high-speed data transfer capability
Solution Approach 2:
The system dynamically allocates the telephone line bandwidth between voice and data transmissions based on real-time needs. The protocol handler can adjust the proportion of bandwidth dedicated to data versus voice, optimizing performance for different types of traffic without requiring dedicated separate lines, thus reducing system overhead while maintaining flexibility and speed

AI summary
The present subject matter relates to apparatus and methodologies for allowing old telephone line capacity to provide near DSL or superior DSL quality telephone connections. A method of handling a telephone call with an associated data package over a telephone system having a power pair of lines and a second pair of communication lines with the steps of: a) determining the types of data desired to create a data group from the group consisting of voice, picture, bio-marker (finger print, retinal scan, etc.), card holder information (credit card number, etc.), DNIS and ANSI call data, generating at least one first byte digital data from at least one first digital data generator; generating at least one second type digital data from at least one second digital data generator; prioritizing the data between the at least one first byte digital data and at least one second type digital data so that the at least one first byte digital data is given priority; determining the bandwidth associated with transmission of the at least one first byte digital data; preferentially sending the at least one first byte of digital data within the bandwidth associated therewith; and adding bandwidth as required to include the at least one second type digital data. The data is separated and forwarded on at a site remote from the phones. Data is carried to the phone as well as away from the phone using this prioritized process.
