MTP Dual Port Ram Test (#104)
This test is destructive.
The test terminates any PPN SAT session, and it is a coordinated test of the MTP
dual port ram (DPR). The DPR is a section of memory that is shared by the MTP
and by the RISC Processor circuit pack. Control messages and data are passed
through the DPR. The test forces both sides to read and write the DPR
simultaneously in alternate locations.
The DPR test causes the PPN SAT to log off before the test result is displayed.
The test result is determined according to the terminal from which the test is run. If
the test is run from the PPN SAT, system technician should log back in and
examine the Error Log for an error against PR-MAINT, with Error Type 769, no
Aux Data. This error entry indicates that the MTP DPR Test failed and that the
Processor circuit pack should be replaced.
NOTE:
If the test is being run from a terminal other than the PPN SAT (for example,
EPN SAT, remote access, etc.), the test results are displayed on the screen.
NOTE:
A dial-up (through the INADS port) does not display the results discussed in
the previous paragraph. However, a dial-up through data channels does
display these results.
