CDMA Maintenance
Functional Test
Errors and System
Recovery Actions
When a CDMA functional test fails, the RCC hardware error handler (HEH)
software subsystem responds in one of two ways, depending upon the failure:
■
Reports the failure to the ECP, takes action to correct the failure, and then
reports the result of the recovery action to the ECP.
■
Does nothing more than report the failure to the ECP.
The ECP decodes the data in the HEH-initiated report into an output message
and prints the output message at the read-only printer (ROP). In situations where
no automatic recovery action is taken or automatic recovery action fails, the
technician must perform manual recovery procedures from the ECP. Manual
recovery procedures for a failed overhead channel or traffic path functional test
can be found in the Release 3.0 Isolation Strategy memorandum written by
Thomas E. Wing.
When a technician initiates a CDMA functional test, the RCC will report the test
results (pass, fail) to the ECP. In contrast, the RCC will only report the tests results
of a routine (scheduled) CDMA functional test if the test fails. The RCC routine
maintenance scheduler (RMS) software subsystem generates the report (pass,
fail) for manually initiated CDMA functional tests, whereas HEH generates the
report (fail only) for routine CDMA functional tests.
General Errors
Some errors are common to both the overhead channel and traffic path functional
tests. Those errors, together with the automatic recovery actions, are listed and
described below:
■
Functional test timer expired.
The RCC sets a timer at the beginning of a functional test; if the functional
test does not complete before the timer expires, the functional test aborts.
HEH takes no recovery action other than to report the failure to the ECP.
■
RCC-to-CRTUi communication failure
HEH conditionally restores the CRTU and sends a report to the ECP.
■
CRTUi-to-CRTUm communication failure
HEH conditionally restores the CRTU and sends a report to the ECP.
Overhead Channel
Functional Test
Errors
Currently, for a failed overhead channel functional test, HEH does nothing more
than report the failure to the ECP. The technician must perform manual recovery
procedures from the ECP.
What follows is an RMS-generated report for a manually initiated overhead
channel functional test that passed:
