approximately every 10 minutes. If the hardware problem is resolved, the
"leaky bucket" strategy should clear the alarm in approximately 30
minutes. However, if the alarm does NOT clear in 30 minutes, the circuit
pack should be replaced.
i. This error can be ignored, but look for other errors on this circuit pack.
j. This error is not service-affecting and no action is required.
k. This error indicates that no ringing current is detected. Run Test #51,
Ringing Application Test, and follow the procedures for Test #51. This
error is only applicable to Analog Line circuit packs.
l. The hyperactive circuit pack is out-of-service and may exhibit one or more
of the following symptoms:
1. The common circuit pack level tests such as Test #51 and/or Test
#220 are aborting with error code 2000.
2. The tests run on the ports of this circuit pack are returning with a
NO-BOARD.
3. A busyout/release of the circuit pack has no affect on test results.
4. A list configuration command shows that the circuit pack and
ports are properly installed.
If the XXX-BD is not a TN754 Digital Line Circuit Pack (DIG-BD), and if this
error happens again within 15 minutes, replace the circuit pack. If the
XXX-BD is a TN754 Digital Line Circuit Pack (DIG-BD), check the alarm
level. If the alarm level is a WARNING, this indicates that users are
probably causing the hyperactivity by playing with their digital stations. If
the circuit pack is really hyperactive, this alarm is upgraded to a MINOR
alarm within one hour. If the alarm level is a MINOR alarm, replace the
circuit pack. (Refer to the ‘‘
Handling Control Circuit Packs’’ section in
Chapter 5, ‘‘
Routine Maintenance Procedures’’.)
m. This error indicates that no neon current is detected. Run Test #220, Neon
Test, and follow the procedures for Test #220. This error is applicable only
to TN769 and TN746 Analog Line circuit packs.
n. This error is not service-affecting and no action is required.
o. 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.
