Protocol Translation Gateway for ISDN Telephone Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems, particularly automatic call distributors (ACDs), face challenges in reducing costs associated with using older telephones, especially ISDN telephones, due to the increased efficiency of Internet-based voice call processing.
Innovation Solution
The implementation of a method and apparatus that translates control instructions and voice information between Internet packet formats and repeating frame protocols, allowing ISDN telephones to be used in Internet-based voice calls through protocol conversion, reducing the need for costly upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If Internet-based voice call processing is implemented, then toll charges are significantly reduced, but older ISDN telephones cannot be directly used and require costly upgrades
Solution Approach 1:
A gateway device is introduced as an intermediary between the Internet-based ACD system and legacy ISDN telephones. The gateway performs protocol translation, converting Internet packet format control instructions into ISDN repeating frame protocols, enabling older telephones to communicate over Internet-based voice calls without hardware upgrades.
Solution Approach 2:
The system changes the protocol parameter format from Internet packet format to ISDN repeating frame protocol through translation. This parameter transformation allows the same voice call functionality to operate across different protocol environments, maintaining compatibility with legacy ISDN equipment while utilizing Internet-based calling.
2Adaptability or versatility
If protocol translation is implemented to maintain ISDN telephone compatibility, then device complexity increases, but cost-effective operation of legacy equipment is achieved
Solution Approach 1:
The gateway serves as a dedicated intermediary device that consolidates all protocol translation functionality in a single location. This centralized approach manages the complexity of protocol conversion between Internet packet format and ISDN repeating frame protocols, isolating the complexity from both the ACD system and the legacy telephones.

AI summary
A method and apparatus are provided for operating a data protocol telephone that is used in a call for exchanging voice information between a first party human user of the data protocol telephone and a second human party to the call at least partially through the Internet. The method includes the steps of translating a set of control instructions exchanged over a first path between a controller of the data protocol telephone and the data protocol telephone, where said exchanged control instructions are translated between an Internet packet format readable by the controller and a set of repeating frame protocols readable by the data protocol telephone and transcoding the translated control instructions on the first Internet path and the voice information exchanged on a second Internet path, where the second Internet path is different than the first Internet path, said translated control instructions and exchanged voice information being transcoded between a single time division multiplexed repeating frame of the data protocol telephone and a packet format of the Internet.
