A Micro Telecommunications Computing Architecture, Microtca, Test System and Method

A Micro Telecommunications Computing Architecture, MicroTCA, test system comprises an interconnect for communication between modules of the MicroTCA test system. A test controller module, such as a JTAG, Switch Module, is coupled to the interconnect and comprises an interface for coupling to at least one unit under test. An interface module, such as a MicroTCA Carrier Hub module, receives test instruction messages from an external connection and forwards these to the test controller module via the interconnect. The test instruction messages comprise test input data for at least a first unit under test. The test controller module furthermore comprises an extraction processor for extracting the test input data from the test instruction messages; and a test controller for performing a test of the first unit under test in response to the test input data.
