Alarm DescriptionAlarm Name
1958 BTS Overload:
Aggregate Access
Threshold 3 Reached
A capacity overload alarm indicates that the aggregate of both call setups
and registration capacity ceiling was reached and mobile restrictions
associated with the alarm will be in effect for the mobile originations and
registrations. This alarm is cleared when the overload condition is no
longer in effect. The reporting mechanism is disabled by default for all
overload alarms in this category and can be changed via Recent Change
command EDIT CARRIER/SECTOR/BTS CONGESTCONF at
OMCR. Supplemental data represents the state of the system after the
alarm actions have taken place.
1959 Global Service
Redirection Threshold
Reached: New Calls
This alarm indicates that all mobiles in the affected access class will be
redirected to an overlaid analog system or to another CDMA system until
the rate drops below the threshold level for new calls. This alarm is
cleared when the overload condition is no longer in effect. The default is
set to DISABLED for all overload alarms in this category and can be
changed via the Recent Change command EDIT CARRIER/SECTOR/
BTS CONGESTCONF at the OMCR. Supplemental data represents the
state of the system after the alarm actions have taken place.
1960 Global Service
Redirection Threshold
Reached: Registrations
This alarm indicates that all mobiles in the affected access class will be
redirected to an overlaid analog system or to another CDMA system until
the rate drops below the threshold level for new calls. This alarm is
cleared when the overload condition is no longer in effect. The default is
set to DISABLED for all overload alarms in this category and can be
changed via the Recent Change command EDIT CARRIER/SECTOR/
BTS CONGESTCONF at the OMCR. Supplemental data represents the
state of the system after the alarm actions have taken place.
1961 Global Service
Redirection Threshold
Reached: Aggregate
This alarm indicates that all mobiles in the affected access class will be
redirected to an overlaid analog system or to another CDMA system until
the rate drops below the threshold level for new calls. This alarm is
cleared when the overload condition is no longer in effect. The default is
set to DISABLED for all overload alarms in this category and can be
changed via the Recent Change command EDIT CARRIER/SECTOR/
BTS CONGESTCONF at the OMCR. Supplemental data represents the
state of the system after the alarm actions have taken place.
LPAC Alarms
3901 LPAC: High Power
Over Limit Alarm –
Unit A
The output detector on the unit monitors the output power. An alarm
generates when the output power surpasses a preset threshold. At this
point, the PA is outputting more power than it can sustain, and damage
will result if the PA continues to operate. A typical scenario that would
cause a high power over limit alarm would be when power into the PA is
more than it can safely sustain. This would cause an input overload,
which is detected by the output detector, and the BTS would
automatically reduce its output power. The BTS will remain in service
after this alarm. Some calls may be dropped.
