» Selftest
Executes a system self-test, and the LCD displays the
Pass
or
Fail
when the
test is complete. Options include Run Selftest, Show Results, and Clear Re-
sults.
»» Run Selftest
Initiates a self-test. When you select this option, the prompt
Selftest, Are
You Sure Y/N?
displays. To initiate the self-test, select
Y
and press
Enter
.
Select
N
and press
Enter
to cancel the self-test.
If you select
Y
and proceed with the self-test, the LCD displays the message
Selftest in progress....
When the self-test is complete with no failures
detected, the
OK
LED illuminates and the LCD momentarily displays
Self-Test Passed.
If failures are detected, a list of failures displays in the
LCD window.
The full self-test procedure consists of the following steps:
1.
Board-level tests. An on-board processor executes a series of tests
checking the circuitry on the board.
2.
RAM tests; EPROM checksum.
3.
TDM map tests.
4.
On-board data path.
Sending a known test pattern through an on-
board loop.
5.
Board-to-board interface test.
Verifies the data path, clocks, and con-
trol signals. A test pattern is sent from the controller through a loop-
back on all other boards and checked on the controller.
During a self-test, ATLAS 800
PLUS
checks data integrity and verifies proces-
sor control to each port. Each port is looped back and a data pattern is sent
and tested.
»» Show Results
Displays the types of tests performed during a self-test, as well as the results
of the tests. Each item in the list displays either
Passed
or
Failed
. A RAM
test failure indicates a controller board problem. If a slot fails, the module in
the slot may have a problem.The following items display:

DSP RAM
Digital signal processor RAM
RTC RAM
Real time clock RAM
TDM MAP
TDM time slot mapping RAM
DRAM
