2.0 Defining System Diagnostics
2.1
Initialize Diagnostic Data
This option clears all previous diagnostic test results from memory.
2.2
ROM Checksum Verification
The ROM checksum test calculates and displays a checksum to test the integrity of the system software builds
(located in the flash ROM).
If the system passes the test, it displays
Passed
on the screen. If the system fails the test, it displays
Failed
along with the expected and actual checksum value.
2.3
Scratch RAM Test
This test checks the integrity of the scratch RAM area by writing and reading words in memory. The test works
by writing a known pattern, “55AA” into memory and then reading the area of memory back. The system then
writes and reads a second known pattern, “AA55.” This algorithm checks every byte in the the scratch RAM area.
If an error occurs, the system displays a message stating that the test failed. Scratch RAM is considered the
working area of memory for the DXP’s microprocessor. This area of memory is “volatile,” which means that any
data in this area is lost when the system loses power.
2.4
NonVolatile RAM test
This test checks the integrity of the NOV-RAM area of memory. The NOV-RAM area of memory is write
protected and backed up by super capacitors on the DXP’s memory board. The programmed database and SMDRs
are stored in this area of memory. This test uses the same write/read algorithm that the scratch RAM test employs.
2.5
Time Switch Memory Test
This test checks all 560 timeslots with a write/read algorithm pattern similar to that of the scratch/NOV-RAM
test. All voice, data, and tones that pass into and out of the DXP pass through the timeswitch.
