System Technician-Demanded Tests:
Descriptions and Error Codes
Investigate tests in the order they are presented in Table 8-443. For example, by
clearing error codes associated with the DSP Capacity Query test (#1382), you
may also clear errors generated from the other tests in the testing sequence.
DSP Capacity Query Test (#1382)
This test is nondestructive
For the TN802B
When using theTN802B, this test polls the circuit pack for the number of failed
DSPs. If every DSP is functional, the test passes and the board is operating at
maximum capacity. If any DSPs have failed, the test fails and reports the number
of failed DSPs.
A failure of 3 or fewer DSPs does not result in an alarm. A failure of more than 3
and up to 8 DSPs results in a warning alarm. A failure of more than 8 DSPs
results in a minor alarm. In all cases, except when every DSP fails, the
MEDPROPT continues to provide reduced capacity.
For the TN2302
When using the TN2302 this test polls the circuit pack for the state of health of a
specific DSP. If the DSP is bad, an error will be logged and the board will be
polled again. If the circuit pack is still failing, the DSP will be taken out of service
and a MINOR alarm will be raised.
