An integer value that uniquely identifies an alarm filter
profile.
AlarmList
binary
For each unique type of physical entity (i.e., for each set
of physical entities sharing a unique entPhysicalVendorType
OID), there an exists unique alarm space. Observe that it
is not necessary that all the alarms within a space be defined.
An OCTET STRING represents an alarm list, in which each
bit represents an alarm type. The bits in the first octet
represent alarm types identified by the integer values 1
through 8, inclusive, The bits in the second octet represent
alarm types identified by the integer values 9 through 16,
inclusive, and so forth. The least significant bit of an
octet represents the alarm type identified by the lowest
integer value, and the most significant bit represents the
alarm type identified by the highest integer value. The
figure shown below illustrates the format of an alarm list.

An alarm list of length N, where N < 32, represents an alarm
list for which alarms N*8 through 255 have the value of '0'.
A special case is an alarm list having a length of '0', which
represents an alarm list of all zeros.
AlarmSeverity
enumeration
Each alarm type defined by a vendor type employed by the
system has an associated severity. Bellcore TR-NWT-000474
defines these severities as follows:
'critical' An alarm used to indicate a severe, service-
affecting condition has occurred and that immediate
corrective action is imperative, regardless of the
time of day or day of the week.
'major' An alarm used for hardware or software conditions
that indicate a serious disruption of service or the
malfunctioning or failure of important hardware.
These troubles require the immediate attention and
response of a technician to restore or maintain
system capability. The urgency is less than in
critical situations because of a lesser immediate
or impending effect on service or system
performance.
'minor' An alarm used for troubles that do not have a
serious effect on service to customers or for
troubles in hardware that are not essential to
the operation of the system.
'info' An indication used to raise attention to a condition
that could possibly be an impending problem or to
notify the customer of an event that improves
operation.
AlarmSeverityOrZero
int32
A value of either '0' or a valid alarm severity.
AlarmType
int32
An arbitrary integer value that uniquely identifies an event
relative to a physical entity contained by a system.
