1.3.6.1.4.1.5591.1.1.4 |
| This MIB contains information that must be supported by all HMS
network elements, including but not limited to, transponders,
line monitors, amplifiers, fiber nodes, and power supplies.
The Property MIB defines the 'properties' that may be associated with
each parameter. This MIB is defined so that these 'properties' may be
applied to any parameter, because the index to the MIB is the object
identifier of the parameter. The purpose of a 'property' is to provide
a mechanism to manage alarm thresholds. It is not the responsibility of
the transponder to check for violation of the above recommendations.
The element manager is responsible for checking alarm limit values.
Entries in the property table are specifically for 'analog' parameters.
The discrete property table is used to monitor other parameters.
Each property entry has four alarm threshold levels that may be established.
These are:
LOLO Alarm threshold for the extreme low condition.
LO Alarm threshold for the low condition.
HI Alarm threshold for the high condition.
HIHI Alarm threshold for the extreme high condition.
In addition, there is a 'Deadband' setting which applies to all alarm thresholds.
After an alarm occurs, the parameter value must pass back over the alarm threshold
by this amount for the alarm condition to be cleared. This Deadband is smaller than
the distance between any two alarm thresholds to avoid indeterminate states.
Alarm detection for each threshold is controlled by a specific bit in the alarmEnable
variable for the entry. Alarm detection is active when the corresponding bit in
alarmEnable is enabled.
When an alarm condition is detected, in either the propertyTable or the discretePropertyTable,
an entry is created in the alarm log ( see HMS023Rx.MIB ) and an alarmEvent SNMP trap sent
by the transponder/agent.
NOTE
Parameters which do not 'exist' must NOT have properties that are accessible. For example, in
the HMS027 MIB (SCTE 38-4), the MIB object psOutputPowerSupport indicates whether or not the
power supply supports the psPowerOut object. If the psPowerOut object is NOT supported, then
the properties normally associated with the psPowerOut object must not be accessible.
Some devices only require 16 bit integer or smaller and therefore only support 16 bit (or smaller)
values. Values outside of the supported range will return a bad value error.

1.3.6.1.4.1.5591.1.1.1.1 |
| A list of information about each property.
The OID suffix for an entry in this table is constructed by
appending the length of parameterOID and then the components
of parameterOID to identify an instance.
The first two components of parameterOID will generally be
1.3 which will be encoded separately as 1 and 3, not as a
single value of 43 (decimal). When parameterOID identifies
a scalar object, it is expected that the final suffix of .0
will be included.
If parameterOID was 1.3.5.0, then 4.1.3.5.0 are the resulting
components of the OID suffix. |

| currentAlarmOID |
1.3.6.1.4.1.5591.1.1.2.1.1 |
| This is the OID of the alarmed object whose current value makes
an alarm active.
In the case of the alarmed analog object, the value of
this object is equal to the value of the index parameterOID
of the propertyTable.
In the case of the alarmed discrete object, the value of
this object is equal to the value of the index discreteParameterOID
of the discretePropertyTable.
Please note that in the case of the alarmed discrete object,
the value of this object is not equal to the identity part of
the OID of the instances in the corresponding row of
the discretePropertyTable.
Example 1. Object commonInternalTemperature (HMS024).
If object commonInternalTemperature has a major alarm for
a HIHI threshold value of 100 degrees Celsius defined in
the propertyTable, and this alarm occurs then:
(1) 'currentAlarmOID.12.commonInternalTemperature.0'
instance will have the value 'commonInternalTemperature.0';
(2) 'currentAlarmAlarmState.12.commonInternalTemperature.0'
instance will have the value caasHIHI(2);
(3) 'currentAlarmAlarmValue.12.commonInternalTemperature.0'
instance will have the value 100.
Notice the presence of 12 in the OIDs of the instances
above. Number 12 is the length of the 'commonInternalTemperature.0'
OID, which is '1.3.6.1.4.1.5591.1.3.1.13.0'.
Example 2. Object fnOpticalReceiverABSwitchState (HMS025).
If object 'fnOpticalReceiverABSwitchState.1', which is the first
instance of A/B switch in a fiber node, has a major alarm for
a value pathB(2) defined in the discretePropertyTable, and this
alarm occurs then:
(1) 'currentAlarmOID.13.fnOpticalReceiverABSwitchState.1' instance
will have the value 'fnOpticalReceiverABSwitchState.1';
(2) 'currentAlarmAlarmState.13.fnOpticalReceiverABSwitchState.1'
instance will have the value caasDiscreteMajor(6);
(3) 'currentAlarmAlarmValue.13.fnOpticalReceiverABSwitchState.1'
instance will have the value pathB(2).
Notice the presence of 13 in the OIDs of the instances above.
Number 13 is the length of the 'fnOpticalReceiverABSwitchState.1'
OID, which is '1.3.6.1.4.1.5591.1.5.13.1.4.1'.
Example 3. Object heCommonTemperature (HMS111).
If object 'commonInternalTemperature.1' has a major alarm for
a HIHI threshold value of 60 degrees Celsius defined in
the propertyTable, and this alarm occurs then:
(1) 'currentAlarmOID.18.heCommonTemperature.1'
instance will have the value 'heCommonTemperature.1';
(2) 'currentAlarmAlarmState.18.heCommonTemperature.1'
instance will have the value caasHIHI(2);
(3) 'currentAlarmAlarmValue.18.heCommonTemperature.1'
instance will have the value 600.
Notice the presence of 18 in the OIDs of the instances
above. Number 18 is the length of the 'heCommonTemperature.1'
OID, which is '1.3.6.1.4.1.5591.1.11.2.1.1.1.1.1.1.2.1'.
Example 4. Object heOpTxLaserOutputStatus (HMS112).
If object 'heOpTxLaserOutputStatus.1.2', which is the second laser
instance in the first instance of the headend optical transmitter,
has a major alarm for a value off(1) defined in
the discretePropertyTable, and this alarm occurs then:
(1) 'currentAlarmOID.18.heOpTxLaserOutputStatus.1.2' instance
will have the value 'heOpTxLaserOutputStatus.1.2';
(2) 'currentAlarmAlarmState.18.heOpTxLaserOutputStatus.1.2'
instance will have the value caasDiscreteMajor(6);
(3) 'currentAlarmAlarmValue.18.heOpTxLaserOutputStatus.1.2'
instance will have the value off(1).
Notice the presence of 18 in the OIDs of the instances above.
Number 18 is the length of the 'heOpTxLaserOutputStatus.2'
OID, which is '1.3.6.1.4.1.5591.1.11.1.1.1.1.3.1.8.1.2'.
