Wiring Management System Endpoint ID Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wiring management systems, identifying wiring abnormalities between service apparatuses and functional units is cumbersome, requiring manual checks and significant man-hours, as the system cannot determine abnormalities until the transmission path is opened, and it is difficult to pinpoint issues between specific units.
Innovation Solution
A wiring management system and method that utilize a transmission network management apparatus with a database to store and associate unique endpoint names and IDs, allowing for the identification of wiring abnormalities by comparing expected and received endpoint IDs, enabling automated detection of incorrect connections and data input errors.

Engineering Contradiction Analysis
1Reliability
If manual wiring checks are performed after transmission path is opened, then wiring abnormalities can be detected, but significant man-hours are required and the process is cumbersome
Solution Approach 1:
The system performs wiring verification before the transmission path is opened by having functional units transmit endpoint IDs through the wiring to the transmission network management apparatus. This preliminary action allows abnormal wiring to be detected during the configuration phase rather than after the transmission path is opened, significantly reducing the time required for manual checks.
Solution Approach 2:
The functional units automatically transmit their endpoint IDs through the wiring to the transmission network management apparatus without requiring manual intervention. The system self-verifies wiring correctness by comparing received endpoint IDs with expected values stored in the database, eliminating the need for manual wiring checks and reducing man-hours required.
2Loss of time
If endpoint ID verification is performed before transmission path is opened, then wiring abnormalities can be identified early, but the system complexity increases
Solution Approach 1:
The transmission network management apparatus performs multiple functions: it stores endpoint ID information in the database, receives endpoint IDs from functional units, compares received IDs with expected values, and determines wiring abnormalities. By consolidating these functions in a single apparatus, the system achieves early abnormality detection without proportionally increasing overall system complexity.
Solution Approach 2:
The transmission network management apparatus acts as an intermediary between functional units and the transmission path. It receives endpoint IDs from functional units, verifies them against stored expected values, and determines wiring abnormalities. This intermediary role allows centralized verification without requiring complex distributed verification mechanisms across all functional units.
3Ease of operation
If automated endpoint ID comparison is implemented, then manual effort is reduced, but data management complexity increases
Solution Approach 1:
The system creates a digital copy of wiring configuration information by storing endpoint ID mappings in a database. Instead of manual verification, the system automatically compares received endpoint IDs with the copied expected values from the database. This copying approach simplifies the verification operation while the database management complexity is contained through structured storage of endpoint ID relationships.

AI summary
When separate service apparatuses that provide various communication services to users are connected by a wiring with communication functional units interposed, if there is a wiring abnormality, the location of the abnormality is easily identified. When a wiring connection is completed between separated service apparatuses X and Y that provide various communication services to user terminals 31 and 32 with communication functional units A1 and B2 interposed, a wiring management system 10A includes a transmission network management apparatus 14A that identifies a wiring abnormality. The transmission network management apparatus 14A associates endpoint names of the service apparatuses X and Y and of the functional units A1 and B2 with opposite endpoint names on the opposite sides, defines opposite endpoint IDs of the endpoints of the functional units A1 and B2 as expected values, and saves the end points in association with the opposite endpoint IDs in a DB 14b. Upon completing the wiring connection between the service apparatuses X and Y, an opposite endpoint ID of each of the functional units A1 and B2 and the service apparatuses X and Y opposite to predetermined functional units A1 and B2 is received as a received value via a wiring, and if the received value does not match the expected value, it is determined that the wiring is abnormal.
