e. The circuit pack d etected an Angel on-b oard hardware failure. The
reported aux data values c orrespond 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 b y using the busyout board PCSS, reset board
PCSS, and release board PCSS command s. When reset, the circuit pac k
executes a set of tests to detec t the presence of any of the above faults.
The detection of one these errors during initialization causes the circ uit
pack to lock up and appear insane to the s ystem. See the repair
procedures in note b) f or Error Type 1.
f. This MMI circuit pack rep orted a loss of MMI synchronization. Refer to Test
(#1123) for repair proced ures.
g. A failure of the time slot interchanger has be en 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-b oard circuitry is
healthy. Retire the alarm using the test board PCSS long clear command
followed by release board PCSS.
h. The circuit pack is hyp eractive; that is, it is flooding the switch with
messages sent over the control ch annel. The circuit pack is taken out of
service when a threshold number of these errors is rep orted to the switch.
Clear the alarm using the following c ommands: 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 proced ures.
j. The TSI Looparound Test (#1108) failed. See the description of this test
and follow the repair proc edures.
System Technician-Demanded Tests:
Descriptions and Error Code
Always investigate tests in the order p resented in the table belo w when
inspecting errors in the system . By clearing error cod es associated with the TSI
Crosstalk Test (#6), for example, you may also clear errors generated from other
tests in the testing sequenc e.
