MMI-BD
Issue 1 June 2005 1659
f. Error Type 513: 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
Use busyout board location, reset board location, and release board
location. 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.
g. Error Type 769: this MMI circuit pack reported a loss of MMI synchronization. Refer to
Test #1123 for repair procedures.
h. Error Type 1281: a failure of the time slot interchanger was detected. Reset the circuit pack
using busyout board location, reset board location, and release board
location. If the reset passes, then the on-board circuitry is healthy. Retire the alarm using
test board location long clear followed by release board location.
i. Error Type 1538: the circuit pack is hyperactive and 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 busyout board
location, reset board location, test board location long clear, and
release board location. If the error recurs within 10 minutes, replace the circuit pack.
j. Error Type 1793: the TSI Cross Talk test (#6) failed. See the description of this test, and
follow its repair procedures.
k. Error Type 2049: the TSI Loop-around test (#1108) failed. See the description of this test,
and follow its repair procedures.
