Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for verifying connectivity between a Cell Site Router (CSR) and a server rely on visual inspection, which is prone to errors and costly to correct, especially when technicians need to dispatch to base station sites.
Innovation Solution
A method and system for accurate cable verification between a CSR and a server, involving a wiring configuration with pairings of CSR and server ports, and a script to obtain and match MAC addresses, thereby ensuring correct connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection is used for cable verification, then the process is simple and quick, but it is prone to errors and costly to correct
Solution Approach 1:
The patent replaces the mechanical visual inspection method with an automated electronic verification system. The system uses network protocols to automatically detect and verify cable connections by exchanging identification information between devices at opposite ends of cables, eliminating the need for manual visual inspection while significantly improving accuracy.
Solution Approach 2:
The verification system performs self-verification without requiring manual intervention. The system automatically identifies devices, exchanges connection information, and verifies cable integrity through automated network protocols, allowing the system to verify itself without human operators performing manual checks.
2Reliability
If visual inspection is used for cable verification, then no additional hardware is needed, but technicians must dispatch to base station sites to correct errors
Solution Approach 1:
The system performs cable verification before final deployment or during the configuration phase. By conducting verification tests in advance using automated network protocols, the system identifies and corrects connection errors before they cause operational failures, eliminating the need for later technician dispatches to base station sites.
Solution Approach 2:
The verification system provides automatic feedback on connection status and identifies specific cable or port issues. This feedback mechanism allows the system to detect connectivity problems and provide diagnostic information that enables rapid correction without requiring physical visits to remote locations.
3Ease of operation
If ports are visually inspected, then the process is manual and straightforward, but ports look alike and cabling mistakes occur
Solution Approach 1:
The system uses distinctive identification information and status indicators (analogous to color coding) to differentiate between various ports and cable connections. Network devices display unique identifiers and connection status information that make it easy to distinguish between similar ports, preventing connection errors while maintaining operational simplicity.
Solution Approach 2:
The patent replaces manual visual differentiation of similar ports with automated electronic identification. Network protocols automatically distinguish between ports using unique device identifiers and connection metadata, eliminating the ambiguity of visually similar ports while maintaining ease of operation through automated verification.

AI summary
A method for cabling verification of a Cell Site Router (CSR) including CSR ports that are cabled to a server including server ports, the method including: providing a wiring configuration including pairings including a CSR port ID of one of the CSR ports and a server port ID of one of the server ports; connecting, with cables, the server ports with the CSR ports per the pairings; getting, on the server, addresses of the server ports; learning, at the CSR, distal addresses of the server ports connected to each of the CSR ports; matching, based on the pairings, a respective address of a respective server port ID with a respective distal address of a respective CSR port ID. In some embodiments, the getting may be performed by the CSR and the learning may be performed by the server.
