d. Indicates transient communication problems between the switch and this
circuit pack. Execute the
test board UUCSS
command and refer to the
repair procedures for the Control Channel Looparound Test (#52) in the
XXX-BD section.
e. The circuit pack detected an Angel on-board hardware failure. The
reported aux data values correspond to the following detected errors:
4352 - External RAM error
4253 - Internal RAM error
4355 - ROM Checksum error
4357 - Instruction set error
Reset the circuit pack by using the
busyout board UUCSS
,
reset board
UUCSS
, and
release board UUCSS
commands. When reset, the circuit
pack executes a set of tests to detect the presence of any of the above
faults. The detection of one these errors during initialization causes the
circuit pack to lock up and appear insane to the system. See the repair
procedures in note b for Error Type 1.
f. This MMI circuit pack reported a loss of MMI synchronization. Refer to test
#1123 for repair procedures.
g. A failure of the time slot interchanger has been detected. Reset the circuit
pack using the
busyout board UUCSS
,
reset board UUCSS
, and
release board UUCSS
commands. If the reset passes, then the on-board
circuitry is healthy. Retire the alarm using the
test board UUCSS long
clear
command followed by
release board UUCSS
.
h. The circuit pack is hyperactive; that is, it is flooding the switch with
messages sent over the control channel. The circuit pack is taken out of
service when a threshold number of these errors is reported to the switch.
Clear the alarm using the following commands:
busyout board UUCSS
,
reset board UUCSS
,
test board UUCSS long clear
,
release board
UUCSS
. If the error recurs within 10 minutes, replace the circuit pack.
i. The TSI Cross Talk Test (#6) failed. See the description of this test and
follow the repair procedures.
j. The TSI Looparound Test (#1108) failed. See the description of this test
and follow the repair procedures.
System Technician-Demanded Tests:
Descriptions and Error Code
Always investigate tests in the order presented in Table 9-422 below when
inspecting errors in the system. By clearing error codes associated with the TSI
Crosstalk Test (#6), for example, you may also clear errors generated from other
tests in the testing sequence.
