Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In inverse multiplexing, determining the assignment of partial signals to transmission paths is challenging, especially in optical transport networks, as existing methods require significant effort and do not provide knowledge of signal allocation, affecting transmission quality and performance.
Innovation Solution
The method involves interrupting transmission paths to identify partial signals by examining the reassembled received signal, utilizing frame structures and rolling systems to determine which partial signals are present or missing, allowing for efficient assignment without additional communication overhead.

Engineering Contradiction Analysis
1Extent of automation
If training data pattern is transmitted over all sections during configuration process, then automatic configuration of transmission link is achieved, but no user data can be transmitted during this phase
Solution Approach 1:
The transmission link is divided into multiple sections, and the training process is segmented to occur only on selected sections rather than all sections simultaneously. This allows other sections to continue transmitting user data without interruption.
Solution Approach 2:
Instead of applying the training data pattern to all transmission sections (excessive action), the method applies it only to selected sections where configuration is needed (partial action), thereby maintaining data transmission capability on other sections.
2Reliability
If signal transmission is interrupted to determine partial signal assignment, then transmission path performance is improved, but transmission continuity is affected
Solution Approach 1:
The transmission link is segmented into multiple sections, and the interruption for assignment determination is applied only to selected sections rather than the entire link. This minimizes the impact on overall transmission continuity while still enabling performance optimization.
Solution Approach 2:
The method interrupts signal transmission only partially (in selected sections) rather than completely across the entire transmission link, thereby maintaining transmission continuity on unaffected sections while still achieving assignment determination.
3Device complexity
If partial signals are assembled without knowledge of signal allocation, then device complexity is reduced, but transmission quality optimization is limited
Solution Approach 1:
The system performs self-diagnosis by automatically determining the assignment of partial signals to transmission sections through monitoring and analysis, without requiring external configuration or complex pre-programming. This maintains low device complexity while enabling quality optimization.
Solution Approach 2:
The method implements a feedback mechanism where the receiver monitors the transmitted signals, determines their assignment to transmission sections, and uses this information to optimize transmission quality. This feedback loop enables quality improvement without increasing fundamental system complexity.

AI summary
The method involves interrupting a signal transmission over transmission links (5a-5d) for a detection process after synchronizing partial signals (S1-S4) to a digital reception signal (E) at a receiver side. Features in the reception signal are detected during the detection process, where the features contain the partial signals incorporated in the reception signal or partial signals not incorporated in the reception signal. The interruption step and the detection step are executed until information is provided for determining the partial signals transmitted over the respective link. An independent claim is also included for a receiver comprising reception units.
