Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing xDSL service emulation and test methods cannot perform both xTU-C and xTU-R emulation tests simultaneously at the same location, leading to resource wastage and inefficiencies in diagnosing faults in broadband network access systems.
Innovation Solution
A device and method that includes a communication module and a testing module, capable of acquiring necessary information and performing both xTU-C and xTU-R emulation tests by connecting the line to be tested to a shared DSLAM port or MODEM, allowing simultaneous testing at the same location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing emulation test methods are used, then testing can be performed, but both xTU-C and xTU-R emulation tests cannot be performed simultaneously at the same location, leading to resource wastage
Solution Approach 1:
The patent combines the xTU-C emulation test and xTU-R emulation test into a single integrated testing device located at the same physical location. This merging allows both types of tests to be performed simultaneously using shared hardware resources, eliminating the need for separate testing locations and reducing resource wastage while improving testing efficiency
Solution Approach 2:
The testing device is designed with multi-functionality to perform both xTU-C emulation testing and xTU-R emulation testing. By making the same physical testing location universal for both test types, the system optimizes resource utilization and allows concurrent testing operations without requiring dedicated separate infrastructure for each test type
2Reliability
If DSLAM ports are allocated for testing, then emulation tests can be conducted, but resources are taken up and DSLAMs with different chassis or manufacturers cannot share ports
Solution Approach 1:
The testing device provides universal testing capability that works across different DSLAM chassis and manufacturers. By making the testing location universal rather than tying it to specific DSLAM ports, the system enables port sharing and interoperability while maintaining test accuracy and reliability across diverse hardware platforms
3Ease of operation
If separate testing locations are used for xTU-C and xTU-R tests, then each test can be performed independently, but resource wastage occurs
Solution Approach 1:
The patent merges the previously separate xTU-C and xTU-R testing operations into a single integrated testing location. This combination maintains the independence and integrity of each test type while eliminating resource wastage associated with duplicate testing infrastructure, achieving both operational independence and resource efficiency

AI summary
A device for emulation test includes a communication module and a testing module. A method for emulation test includes acquiring, by a testing device, information to be tested according to a received test command and acquiring, by the testing device, the type of the DSLAM port to be tested or the MODEM information according to the information to be tested. Subsequently, the testing device informs a wire-grabbing device to connect the line to be tested to itself, performs xTU-C and xTU-R emulation test according to the information to be tested and the type of the DSLAM port to be tested, or the information to be tested and the MODEM information, and reports the testing result. Accordingly, both the xTU-C emulation test and the xTU-R emulation test for the user-side MODEM can be performed at the same location.
