k. A critical failure has been detected in the Packet Bus interface of the
circuit pack. This failure may be due to an on-board fault or a Packet Bus
fault. If the Packet Bus is alarmed, refer to the PKT-BUS Maintenance
documentation for recommended repair procedures.
If the Packet Bus is not alarmed, reset the circuit pack via
busyout board
UUCSS
and
reset board UUCSS
commands. If the circuit pack Restart
Test (#594) passes, then the on board circuitry is healthy. Retire the alarm
via the
test board UUCSS long clear
command. If the circuit pack Restart
Test (#594) fails, replace the circuit pack.
l. This error is not service affecting. No action is required. This error is
reported by the circuit pack when it receives a bad control channel
message from the switch.
m. This error is not service-affecting. No action is required. A bad translation
RAM has been detected, but call continues by using another translation
RAM location.
n. Error type 3999 indicates that 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.System
Technician-Demanded Tests: Descriptions and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the
Control Channel Looparound Test
for example,
you may also clear errors generated from other tests in the testing sequence.
Note:
a. For Control Channel Loop-Around Test (#52), and SAKI Sanity Test (#53)
refer to the respective repair procedures described in "XXX-BD (Common
Port Circuit Pack).”
