Self Test and Supervision
40 Self Test and Supervision
Self Test comprises an initial boot test and X-bus receiver test. The
initial boot test is performed during the start-up of an RU, in order to
test the functionality of the hardware required for the execution of the
application software. The X-bus receiver test is performed at TX
configuration if TX is configured for SW Power Boost, in order to test
the X-bus receiver on the master TX and slave TX.
Supervision is a subsequent activity, which continuously monitors the
correct function of all supervised entities within the RBS. Faults
detected by the supervision function are passed to the Diagnostics and
Fault Handling function for further processing.

If a reference is made to a function described in another chapter please
refer to the table of contents to locate the relevant information.
40.2 Concepts
CRC Cyclic Redundancy Check (CRC code).
The CRC code is often called polynomial
code.
40.3 Self Test
40.3.1 Boot Test
Purpose
The Boot test is an initial test function that determines the functionality
of the RBS hardware. The test ensures that the application software can
be started in the processor.
Preconditions and Initiation
The Boot test is carried out before any normal application processes are
started. The function Restart and Recovery invokes the test.
Description
Invoked by the function Restart and Recovery the processors are tested
implicity by the memory test.
Read/write memories are tested before any other functions. These tests
are fast and destructive to the contents of the memory and control the
two alternate states of a memory bit are tested.
Memory of non-volatile character such as flash and eprom is tested
checksums. The checksum must include the whole content of the
memory, but does not include unused memory with predefined values to
save time and start-up.
Finally, HW functions controlled by the processor, which are necessary
to start the application software and which do not disturb other
processes or associated HW are finally tested.
