MediaLB Interface Test Bench (MITB) facilitates the testing of the physical and link layers of MediaLB 3-Pin/MediaLB 6-Pin interface implementations. The test bench incorporates hardware, firmware and a data checker software for testing control, asynchronous and synchronous data transport. Predefined tests are included. A Graphical User Interface (GUI) is provided to display errors and to configure the generated test patterns. INIC Explorer and OSS Flasher are available to flash and configure the test bench.
