The ORAN Test Platform MX772000PC and O-DU Emulator Platform Software MX773000PC comprise an O-RAN Fronthaul test solution for the O-RAN Radio Unit (O-RU) specified by O-RAN WG4.CONF. As well as supporting the S-Plane Error Addition Test and the O-RU Time Error tolerance evaluation specified by O-RAN WG4.CONF, the software options can be flexibly configured according to the required test items.

ORAN Test Platform MX772000PC
The O-RU evaluation workload is greatly increased by the many required test items. The MX772000PC simplifies O-RU testing by controlling the MT8000A to automate measurement and Pass/Fail evaluation of obtained results. Moreover, since the O-DU Emulator and MT8000A are controlled from a GUI, test cases for automatic measurement are created easily.

Time Synchronization Tolerance Evaluation
While mobile networks require extremely accurate clock synchronization, multi-vendor interoperability issues cause problems such as reduced throughput resulting from decreased clock quality caused by clock drift, multistage switching, and different transmission equipment. The MX773000PC has a function to insert time errors to the S-Plane to simulate reduced clock accuracy at O-RU evaluation.

Efficient M-Plane Setting
Connecting the O-DU Emulator and O-RU requires creation of M-Plane messages to start and set the O-RU. M-Plane messages differ according to the O-RU and editing errors during their creation causes higher labor costs. The MX773000PC not only graphically displays M-Plane messages but also has a message creation and editing function to simplify their creation and reduce editing mistakes, improving the O-DU Emulator and O-RU connection efficiency.

Automated Higher Test Efficiency
The O-RU evaluation workload is greatly increased by the many required test items. The MX772000PC simplifies O-RU testing by controlling the MT8000A to automate measurement and Pass/Fail evaluation of obtained results. Moreover, since the O-DU Emulator and MT8000A are controlled from a GUI, test cases for automatic measurement are created easily.
