IP Terminal Audio Quality Remote Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating audio quality in IP communication terminals are invasive, requiring on-site expert intervention and disrupting terminal usage, especially when multiple terminals are affected, leading to inefficiencies and prolonged service times.
Innovation Solution
A method for remotely evaluating audio quality by embedding an audio device within IP communication terminals that can perform measurements and computations on digital and analog voice signals, allowing remote control via a Telnet connection, enabling automatic or remotely controlled operations while the terminal is in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-site expert intervention is used for audio quality evaluation, then measurement accuracy is improved, but terminal availability deteriorates and service time increases
Solution Approach 1:
The IP terminal performs self-diagnosis of audio quality by automatically executing measurement routines using its own digital signal processor and audio device, eliminating the need for external expert intervention while maintaining measurement accuracy
Solution Approach 2:
A remote diagnostic system acts as an intermediary between the expert and the terminal, allowing remote initiation and retrieval of measurement results without requiring physical presence, thus reducing service time while maintaining measurement capability
2Measurement precision
If on-site expert intervention is used for audio quality evaluation, then measurement accuracy is improved, but terminal availability deteriorates
Solution Approach 1:
The terminal autonomously performs audio quality measurements during normal operation using embedded measurement routines, ensuring continuous availability while maintaining measurement accuracy through self-diagnosis capabilities
Solution Approach 2:
The terminal continuously monitors and pre-evaluates audio quality parameters in the background during normal use, so that diagnostic data is already available when needed, eliminating service disruption while maintaining measurement precision
3Measurement precision
If repetitive on-site interventions are performed for multiple terminals, then comprehensive measurement is improved, but productivity deteriorates
Solution Approach 1:
The measurement system is designed to universally evaluate multiple IP terminals through a single remote interface, allowing one expert to simultaneously or sequentially diagnose numerous terminals without traveling, thus maintaining comprehensive measurement coverage while dramatically improving productivity
Solution Approach 2:
A centralized remote diagnostic server acts as an intermediary that can initiate and collect measurement results from multiple terminals across different locations, enabling comprehensive evaluation of entire terminal fleets without requiring repeated physical interventions
