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 PCSS, reset board
PCSS, and release board PCSS 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 PCSS, reset board PCSS, and release
board PCSS commands. If the reset passes, then the on-board circuitry is
healthy. Retire the alarm using the test board PCSS long clear command
followed by release board PCSS.
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 PCSS,
reset board PCSS, test board PCSS long clear, release board PCSS. 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 the table 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.
