ANN-BD (Announcement circuit pack)
Issue 1 June 2005 453
i. Error Type 513: when reported with Aux Data in the range of 4352 to 4358, the circuit pack
has reported a hardware failure on the circuit pack. The circuit pack should be replaced.
Replacing the circuit pack results in loss of integrated announcements (TN750/B only). See
General notes
on page 465 near the beginning of this Maintenance procedure.
j. Error Types 1025 and 3840: not service-affecting, no action is required.
k. Error Type 1281: the speech processor (SP) found a fault in the speech main memory
(SMM) (that is, it found one or more faulty memory locations). Whenever this error is
logged, error 2817 is also logged [see Note (m
)], which causes the maintenance system to
run the Announcement Checksum Test (#209) to determine if the bad memory location was
being used by an announcement.
l. Error Type 1538: the hyperactive circuit pack is out-of-service and may exhibit one or more
of the following symptoms:
1. The tests run on the ports of this circuit pack are returning with a NO-BOARD.
2. A busyout/release of the circuit pack has no effect on test results.
3. A list configuration command shows that the circuit pack and ports are properly
installed.
The system tries to restore the circuit pack within 15 minutes. If the error recurs after 15
minutes, replace the circuit pack. (Refer to Reseating and replacing circuit packs
in
Maintenance Procedures (03-300192).)
m. Error Types 2049 and 2817: logged in conjunction with Error Type 1281, Aux Data 17699.
Because Error Type 1281 means that a defective speech memory location was found, [see
Note (k
)] the announcement checksum error is also logged. This causes the Announcement
Checksum Test (#209) to run, which determines if the defective memory location has
corrupted any recorded announcements. If the Checksum Test passes, the faulty memory
location is currently not being used, and the SP marks the location as faulty to ensure that
future announcements do not attempt to use it.
Note:
Note: As memory locations are marked faulty, the amount of available memory
decreases, which decreases the total amount of announcement time available on
the circuit pack.
n. Error Type 2049
: transient error that does not cause an alarm can occasionally occur
during a SPE, TDM BUS, or Tone Clock interchange. It is possible for a marginal
Tone-Clock circuit pack to cause this error against the ANN-BD without alarming the
TONE-BD. If this error occurs again, replacing the Tone-Clock circuit pack may clear up this
error. See the FAIL case in the Clock Match Inquiry Test (#212).
o. Error type 3999: the circuit pack sent a large number of control channel messages to the
switch within a short period of time. If error type 1538 is also present, then the circuit pack
was taken out-of-service due to hyperactivity. If error type 1538 is not present, then the
circuit pack has not been taken out-of-service, but it has generated 50% of the messages
necessary to be considered hyperactive. This may be completely normal during heavy
traffic periods. However, if this error type is logged when the circuit pack is being lightly
used, it may indicate a problem with the circuit pack or the equipment attached to it.
