Announcement Checksum Test (#209)
Associated with every recorded announcement is a checksum. In this test, the SP
checks a stored global checksum covering all recorded announcements against a
calculated one and returns the results to the maintenance system. If the global
checksum failed, maintenance requests the SP to check each individual
announcement’s checksum.
If the test fails, then it returns the total number of defective announcements found.
In addition, associated with each failure is an error in the Error Log (Error Type
14). The Aux Data indicates the number of the first defective announcement
found. This number corresponds to the announcement numbers on the
announcement form. The extension relating to the announcement can be
determined by the display announcement command.
