When Enable is changed to true then Status SHOULD change to Up if and only if the interface is able to transmit and receive network traffic; it SHOULD change to Dormant if and only if the interface is operable but is waiting for external actions before it can transmit and receive network traffic (and subsequently change to Up if still operable when the expected actions have completed); it SHOULD change to LowerLayerDown if and only if the interface is prevented from entering the Up state because one or more of the interfaces beneath it is down; it SHOULD remain in the Error state if there is an error or other fault condition detected on the interface; it SHOULD remain in the NotPresent state if the interface has missing (typically hardware) components; it SHOULD change to Unknown if the state of the interface can not be determined for some reason.

This parameter is based on ifOperStatus from [RFC2863].

[docsIf3CmSpectrumAnalysisCtrlCmdEnable/1.3.6.1.4.1.4491.2.1.20.1.34.1] This attribute is used to enable or disable the spectrum analyzer feature. Setting this attribute to true triggers the CM to initiate measurements for the spectrum analyzer feature based on the other configuration attributes for the feature. By default, the feature is disabled unless explicitly enabled.

Note that the feature may be disabled by the system under certain circumstances if the spectrum analyzer would affect critical services. In such a case, the attribute will return false when read, and will reject sets to true with an error. Once the feature is enabled, any change to this object’s configuration might not be effective until the feature is re-enabled again.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be false.

[docsIf3CmSpectrumAnalysisCtrlCmdInactivityTimeout/1.3.6.1.4.1.4491.2.1.20.1.34.2] This attribute controls the length of time after the last spectrum analysis measurement before the feature is automatically disabled. If set to a value of 0, the feature will remain enabled until it is explicitly disabled.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 300.

[docsIf3CmSpectrumAnalysisCtrlCmdFirstSegmentCenterFrequency/1.3.6.1.4.1.4491.2.1.20.1.34.3] This attribute controls the center frequency of the first segment for the spectrum analysis measurement. The frequency bins for this segment lie symmetrically to the left and right of this center frequency.

If the number of bins in a segment is odd, the segment center frequency lies directly on the center bin.

If the number of bins in a segment is even, the segment center frequency lies halfway between two bins.

Changing the value of this attribute may result in changes to the Result table. Note that if this parameter is set to an invalid value, the device may return an error, or may adjust the value of the parameter to the closest valid value.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 93000000.

[docsIf3CmSpectrumAnalysisCtrlCmdLastSegmentCenterFrequency/1.3.6.1.4.1.4491.2.1.20.1.34.4] This attribute controls the center frequency of the last segment of the spectrum analysis measurement.

The frequency bins for this segment lie symmetrically to the left and right of this center frequency. If the number of bins in a segment is odd, the segment center frequency lies directly on the center bin. If the number of bins in a segment is even, the segment center frequency lies halfway between two bins.

The value of the LastSegmentCenterFrequency should be equal to the FirstSegmentCenterFrequency plus and integer number of segment spans as determined by the SegmentFrequencySpan.

Changing the value of this attribute may result in changes to the Result table.

Note that if this parameter is set to an invalid value, the device may return an error, or may adjust the value of the parameter to the closest valid value.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 993000000.

[docsIf3CmSpectrumAnalysisCtrlCmdSegmentFrequencySpan/1.3.6.1.4.1.4491.2.1.20.1.34.5] This attribute controls the frequency span of each segment (instance) of the Result.{i} table.

If set to a value of 0, then a default span will be chosen based on the hardware capabilities of the device. Segments are contiguous from the FirstSegmentCenterFrequency to the LastSegmentCenterFrequency and the center frequency for each successive segment is incremented by the SegmentFrequencySpan. The number of segments is (LastSegmentCenterFrequency - FirstSegmentCenterFrequency)/SegmentFrequencySpan + 1. A segment is equivalent to an instance in the Result table. The chosen SegmentFrequencySpan affects the number of entries in Result table. A more granular SegmentFrequencySpan may adversely affect the amount of time needed to query the table entries in addition to possibly increasing the acquisition time.

Changing the value of this attribute may result in changes to Result table.

Note that if this parameter is set to an invalid value, the device may return an error, or may adjust the value of the parameter to the closest valid value.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 7500000.

[docsIf3CmSpectrumAnalysisCtrlCmdNumBinsPerSegment/1.3.6.1.4.1.4491.2.1.20.1.34.6] This parameter controls the number of bins collected by the measurement performed for each segment (instance) in the Result table.

Note that if this parameter is set to an invalid value, the device may return an error, or may adjust the value of the parameter to the closest valid value.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 256.

[docsIf3CmSpectrumAnalysisCtrlCmdEquivalentNoiseBandwidth/1.3.6.1.4.1.4491.2.1.20.1.34.7] This parameter allows the user to request an equivalent noise bandwidth for the resolution bandwidth filter used in the spectrum analysis. This corresponds to the spectral width of the window function used when performing a discrete Fourier transform for the analysis.

The window function which corresponds to a value written to this parameter may be obtained by reading the value of WindowFunction.

If an unsupported value is requested, the device may return an error, or choose the closest valid value to the one which is requested. If the closest value is chosen, then a subsequent read of this parameter will return the actual value which is in use.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 150.

[docsIf3CmSpectrumAnalysisCtrlCmdWindowFunction/1.3.6.1.4.1.4491.2.1.20.1.34.8] [SpectrumAnalysisWindowFunction] This parameter controls or indicates the windowing function which will be used when performing the discrete Fourier transform for the analysis. The WindowFunction and the Equivalent Noise Bandwidth are related. If a particular WindowFunction is selected, then the EquivalentNoiseBandwidth for the function which is in use, will be reported by the EquivalentNoiseBandwidth parameter. Alternatively if an EquivalentNoiseBandwidth value is chosen then if a WindowFunction function representing that EquivalentNoiseBandwidth is defined in the CM, that value will be reported in WindowFunction, or a value of Other will be reported. Use of “modern” windowing functions not yet defined will likely be reported as Other.

Enumeration of:

• Other
• Hann
• BlackmanHarris
• Rectangular
• Hamming
• FlatTop
• Gaussian
• Chebyshev

Note that all window functions may not be supported by all devices. If an attempt is made to set the object to an unsupported window function, or if writing of the WindowFunction is not supported, an error will be returned.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

[docsIf3CmSpectrumAnalysisCtrlCmdNumberOfAverages/1.3.6.1.4.1.4491.2.1.20.1.34.9] This parameter controls the number of averages that will be performed on spectral bins. The average will be computed using the ‘leaky integrator’ method, where: reported bin value = alpha*accumulated bin values + (1-alpha)*current bin value.

Alpha is one minus the reciprocal of the number of averages. For example, if N=25, then alpha = 0.96. A value of 1 indicates no averaging. Re-writing the number of averages will restart the averaging process. If there are no accumulated values, the accumulators are made equal to the first measured bin amplitudes.

If an attempt is made to set the parameter to an unsupported number of averages, an error will be returned.

See [CM-SP-CM-OSSIv3.1], Proactive Network Maintenance Information Model.

The factory default value MUST be 1.

[docsIf3CmSpectrumAnalysisMeasAmplitudeData/1.3.6.1.4.1.4491.2.1.20.1.35.1.2] [AmplitudeData] This parameter provides a list of the spectral amplitudes as measured at the center frequency specified by the Frequency.
