TEXTUAL-CONVENTION

This data type represents a sequence of spectral amplitudes. Each spectral amplitude value corresponds to a bin. The format of the bin measurement is as follows. Sequence of: 4 bytes: ChCenterFreq The center frequency of the upstream channel. 4 bytes: FreqSpan The width in Hz of the band across which the spectral amplitudes characterizing the channel are measured. 4 bytes: NumberOfBins The number of data points or bins that compose the spectral data. The leftmost bin corresponds to the lower band edge, the rightmost bin corresponds to the upper band edge, and the middle bin center is aligned with the center frequency of the analysis span. 4 bytes: BinSpacing The frequency separation between adjacent bin centers. It is derived from the frequency span and the number of bins or data points. The bin spacing is computed as: BinSpacing = FrequencySpan/(NumberOfBins -1) The larger the number of bins the finer the resolution. 4 bytes: ResolutionBW The resolution bandwidth or equivalent noise bandwidth of each bin. If spectral windowing is used (based on vendor implementation), the bin spacing and resolution bandwidth would not generally be the same. n bytes: Amplitude (2 bytes * NumberOfBins) A sequence of two byte elements. Each element represents the spectral amplitudes in relation to the expected received signal power of a bin, in units of 0.01dB. That is, a test CMTS input signal with square-root raised-cosine spectrum, bandwidth equal to the expected received signal bandwidth, and power equal to the expected received signal power, which is present for the entire spectrum sampling period, will exhibit a spectrum measurement of 0 dB average power in each bin of the signal passband. Each bin element amplitude value format is 2's complement which provides a range of -327.68 dB to 327.67 dB amplitude value for the bin measurement.

TEXTUAL-CONVENTION

This data type represents a sequence of 32-bit positions that defines logical (e.g., AND, OR) operations to match against the channel list Provisioned Mask and Service Flow Required Mask bit positions when the CMTS is determining the service flow for assignment to a bonding group not configured by the management system.

TEXTUAL-CONVENTION

This data type consists of a sequence of 32-bit positions used to select the bonding group or the channel to which a service flow is assigned. DOCSIS defines three types of Attribute Masks for which this type applies: The Provisioned Attribute Mask that is configured to a Bonding Group or a single-channel, whereas the Required Attribute and the Forbidden Attribute Mask are part of the Service Flow QOS Parameter Set to be matched with the Provisioned Attribute Mask of CMTS-configured Bonding Groups or single-channels. DOCSIS reserves the assignment of the meaning of the first 8 bit positions (left to right) as follows: Bit 0: 'bonding' Bit 1: 'lowLatency' Bit 2: 'highAvailability' Bit positions 3-15 are reserved. Bit positions 16-31 are freely assigned by operators to represent their own constraints on the channel(s) selection for a particular service flow.

TEXTUAL-CONVENTION

This data type is an 8-bit number that represents a provisioned Downstream Channel ID (DCID) or a provisioned Upstream Channel ID (UCID). A Channel Id is unique per direction within a MAC Domain.

TEXTUAL-CONVENTION

This data type is a CMTS-derived unique number within a MAC Domain used to reference a Channel Set within the CMTS. Values in the range of 1 to 255 define a single-channel Channel Set and correspond to either the Downstream Channel ID (DCID) or an Upstream Channel ID (UCID) of that channel. Values greater than 255 indicate a Channel Set consisting of two or more channels in the same direction within the MAC Domain. The value zero is reserved for use when the Channel Set is unknown.

TEXTUAL-CONVENTION

This data type represents a unique set of channel IDs in either the upstream or the downstream direction. Each octet represents a UCID or DCID depending on the direction of the channels within the list. The CMTS must ensure that this combination of channels is unique per direction within the MAC Domain. In order to facilitate Channel ID combinatorial uniqueness across all channel lists, a query to retrieve the value of an attribute of this type, returns the set of channels in the channel list in ascending order of Channel Ids.

OBJECT-TYPE

This attribute indicates which, if any, of the Energy Management Features are enabled for this CM. If this attribute returns the em1x1Mode(0) bit set, the CM is configured with the Energy Management 1x1 Feature enabled. If this attribute returns the dlsMode(1) bit set, the CM is configured with the DLS Feature enabled. If this attribute returns all bits cleared, the CM will not request to operate in any Energy Management mode of operation. Note: This attribute only indicates if an Energy Management Feature is enabled/disabled via the CM config file and registration request/response exchange and does not indicate whether the CM is actively operating in an Energy Management Mode.

OBJECT-TYPE

This attribute indicates whether the CM is currently operating in an Energy Management Mode. If this attribute returns the em1x1Mode(0) bit set, the CM is operating in Energy Management 1x1 Mode. If this attribute returns the dlsMode(1) bit set, the CM is operating in DLS Mode. If this attribute returns all bits cleared, the CM is not operating in any Energy Management Mode. This attribute always returns 0x00 (no bits set) in the case when docsIf3CmtsCmRegStatusEnergyMgtEnabled is set to 0x00 (no Energy Management Features enabled). Note: dlsMode(1) and em1x1Mode(0) are mutually exclusive, thus a return value where both of these bits are 'true' is invalid.

OBJECT-TYPE

This table configures the association of downstream and upstream channels to a particular MAC Domain (MD) on a CMTS. The creation of channels and MAC domain object interface instances is vendor-specific. In particular, the assignment of the channel interface index is normally vendor-specific. Therefore, this object is intended only for associating channels to a MAC Domain and assumes that those channels were previously configured. The CMTS may have restrictions on which channels can be configured in the same MAC Domain. For example, it could require the upstream channels to be from the same line card. This table supports the creation and deletion of multiple instances. Creation of a new entry in this table requires the ChId attribute to be set.

OBJECT-TYPE

The conceptual row of docsIf3MdChCfgTable. The ifIndex key corresponds to the MAC Domain interface where the channel is configured. The CMTS persists all instances of MdChCfg across reinitializations.

OBJECT-TYPE

This key represents the interface index of an existing upstream or downstream channel that is configured to be part of the MAC Domain. For the case of upstream interfaces the CMTS could reject the assignment of upstream logical channels under the same physical upstream interface to different MAC Domains.

OBJECT-TYPE

If set to 'true', this attribute configures the downstream channel as Primary-Capable. The default value for a downstream channel is 'true'. This attribute is not relevant for upstream interfaces, therefore it reports the value 'false' for such interfaces. A CMTS may restrict the permitted value of this attribute based upon physical channel capabilities.

OBJECT-TYPE

This key represents the RCP-ID to which this instance applies.

OBJECT-TYPE

This key represents an RCC combination for a particular RcpId either from an RCC configuration object or a CMTS-determined RCC and is unique per combination of MAC Domain ifIndex and RcpId.

OBJECT-TYPE

This attribute identifies an RCC-Configured combination from which this instance was defined. If nonzero, it corresponds to the RccCfg instance from which the RCC was created. Zero means that the RCC was dynamically created by the CMTS.

OBJECT-TYPE

This attribute indicates whether the RCC instance of this object is valid or not. An RCC Status instance from a configured or a dynamic RCC could become invalid, for example, due changes in the topology.

OBJECT-TYPE

This attribute contains the CMTS vendor-specific log information from the Receive Channel Configuration Status encoding.

OBJECT-TYPE

The Receive Channel Configuration table permits an operator to configure how CMs registered with certain Receive Channel Profiles will configure the Receive Channels within their profile. When a CM registers with an RCP for which all Receive Channel Indices (RcIds) are configured in the Receive Module object and all Receive Channels are configured within this object, the CMTS should use the configuration within these objects to set the Receive Channel Configuration returned to the CM in a REG-RSP message. A CMTS may require configuration of all pertinent Receive Module and Receive Channel instances in order to register a CM that reports a Receive Channel Profile (RCP), including any standard Receive Channel Profiles. If the CM reports multiple RCPs, and Receive Module and Receive Channel objects have instances for more than one RCP, the particular RCP selected by the CMTS is not specified. A CMTS is not restricted to assigning Receive Modules based only on the contents of this object. This table supports the creation and deletion of multiple instances. Creation of a new entry in this table requires the ChIfIndex attribute to be set and a valid reference of a RccCfg instance.

OBJECT-TYPE

The conceptual row of docsIf3RxChCfgTable. The ifIndex key corresponds to the MAC Domain interface where the RCC is configured. The CMTS persists all instances of ReceiveChannelCfg across reinitializations.

OBJECT-TYPE

This attribute indicates the Receive Module (via the RmId from the ReceiveModule object) to which this Receive Channel connects. If this object contains a zero value (and thus no Receive Channel Connectivity), the Receive Channel Connectivity TLV is omitted from the RCC.

OBJECT-TYPE

The status of this instance.

OBJECT-TYPE

The Receive Channel Status table reports the status of the statically-configured and dynamically-created Receive Channels within an RCC.

OBJECT-TYPE

The conceptual row of docsIf3RxChStatusTable. The ifIndex key corresponds to the MAC Domain interface where the RCC is configured. When this object is defined on the CM, the value of RccStatusId is always 1.

OBJECT-TYPE

This key represents an identifier for the parameters of the Receive Channel instance within the Receive Channel Profile.

OBJECT-TYPE

This attribute contains the interface index of the Downstream Channel that this Receive Channel Instance defines.

If set to 'true', this attribute indicates the Receive Channel is to be the primary-capable downstream channel for the CM receiving this RCC. Otherwise, the downstream channel is to be a non-primary-capable channel.

OBJECT-TYPE

This attribute identifies the Receive Module to which this Receive Channel connects. A value a zero indicates that the Receive Channel Connectivity TLV is omitted from the RCC.

OBJECT-TYPE

The Receive Module Configuration table permits an operator to configure how CMs with certain Receive Channel Profiles (RCPs) will configure the Receive Modules within their profile upon CM registration. When a CM registers with an RCP for which all Receive Module Indices (RmIds) are configured in this object and all Receive Channels are configured within the Receive Channel (ReceiveChannel) object, the CMTS should use the configuration within these objects to set the Receive Channel Configuration assigned to the CM in a REG-RSP message. A CMTS may require configuration of all pertinent Receive Module and Receive Channel instances (i.e., MIB table entries) in order to register a CM that reports a Receive Channel Profile. If the CM reports multiple RCPs, and Receive Module and Receive Channel objects have instances (i.e., MIB table entries) for more than one RCP reported by the CM, the particular RCP selected by the CMTS is not specified. A CMTS is not restricted to assigning Receive Modules based only on the contents of this table. This object supports the creation and deletion of multiple instances. Creation of a new entry this table requires the reference of a valid RccCfg instance.

OBJECT-TYPE

The conceptual row of docsIf3RxModuleCfgTable. The ifIndex key corresponds to the MAC Domain interface where the RCC is configured.

OBJECT-TYPE

This key represents an identifier of a Receive Module instance within the Receive Channel Profile.

OBJECT-TYPE

This attribute represents the higher level (i.e., closer to RF) Receive Module to which this Receive Module connects. If this object contains a zero value (and thus no Receive Module Connectivity), the Receive Module Connectivity TLV is omitted from the RCC. Within a single instance of the ReceiveModule object, the RmRmConnectivityId attribute cannot contain the same value as the RmId attribute. The RmRmConnectivityId attribute points to a separate ReceiveModule object instance with the same value of RccCfgId.

OBJECT-TYPE

This attribute represents the center frequency, in Hz, and a multiple of 62500, that indicates the lowest frequency channel of the Receive Module, or 0 if not applicable to the Receive Module.

OBJECT-TYPE

The Downstream Adaptive Decision Feedback Equalizer (DFE) is implemented as a Feedforward Equalizer (FFE) and a Feedback Equalizer (FBE). In order to evaluate the composite DFE response it is necessary to normalize the FBE coefficients to 1 and then evaluate the FFT(hffe)/FFT(1,hfbe), where the hfbe coefficients have been normalized to 1 using FbeNormalizationCoefficient. The complex data representing the hffe and hfbe coefficients is contained in the docsIfSigQEqualizationData MIB. It is possible to implement the DFE such that the response is evaluated as FFT(hffe)/FFT(1,-hfbe). In this case the FbeNormalizationCoefficient will be reported as a negative number and the response will be evaluated as FFT(hffe)/FFT(1,hfbe).

OBJECT-TYPE

This attribute specifies whether the CM honors or ignores the CMTS MDD TLV 5.1 setting in order to configure its IP provisioning mode. The CM relies upon the CMTS to facilitate the successful IP address acquisition independently of the MDD. When this attribute is set to 'ipv4Only' the CM will initiate the acquisition of a single IPv4 address for the CM management stack. When this attribute is set to 'ipv6Only' the CM will initiate the acquisition of a single IPv6 address for the CM management stack. When this attribute is set to 'honorMdd' the CM will initiate the acquisition of an IPv6 or IPv4 address as directed by the MDD message for provisioning and operation.

OBJECT-TYPE

This attribute determines if the CM is to automatically reset upon change of the IpProvMode attribute. The attribute has a default value of 'false' (2) which means that the CM does not reset upon change to IpProvMode attribute. When this attribute is set to 'true' (1), the CM resets upon a change to the IpProvMode attribute.

OBJECT-TYPE

This attribute determines how long a CM with IpProvModeResetOnChange set to 'true' waits to reset. When the IpProvModeResetOnChange attribute is set to 'true' (1), the CM will decrement from the configured timer value before resetting. The default value of the IpProvModeResetOnChangeHoldOffTimer is 0 seconds which is equivalent to an immediate reset.

OBJECT-TYPE

This attribute determines if the CM persists the value of IpProvMode across a single reset or across all resets. The default value of this attribute is 'nonVolatile' (3) which means that the CM persists the value of IpProvMode across all resets. The CM persists the value of IpProveMode across only a single reset when IpProvModeStorageType is set to volatile(2). Other StorageType values are not applicable for this object; an attempt to set this object to a value of other(1), permanent(4), or readOnly(5) will be rejected with an error code of inconsistentValue.

OBJECT-TYPE

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 Set operation on the docsIf3CmSpectrumAnalysisCtrlCmd MIB group might not be effective until the feature is re-enabled again.

OBJECT-TYPE

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.

OBJECT-TYPE

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 docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the attribute to the closest valid value.

OBJECT-TYPE

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 attribute 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 docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the attribute to the closest valid value.

OBJECT-TYPE

This attribute controls the frequency span of each segment (instance) in the docsIf3CmSpectrumAnalysisMeasTable. 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 FirstSegementCenterFrequency to the LastSegmentCenterFrequency and the center frequency for each successive segment is incremented by the SegmentFequencySpan. The number of segments is (LastSegmentCenterFrequency - FirstSegmentCenterFrequency)/SegmentFrequencySpan + 1. A segment is equivalent to an instance in the docsIf3CmSpectrumAnalysisMeasTable. The chosen SegmentFrequencySpan affects the number of entries in the docsIf3CmSpectrumAnalysisMeasTable. 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 the docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the object to the closest valid value.

OBJECT-TYPE

This attribute controls the number of bins collected by the measurement performed for each segment (instance) in the docsIf3CmSpectrumAnalysisMeasTable.

OBJECT-TYPE

This attribute 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 object may be obtained by reading the value of the WindowFunction attribute. 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 attribute will return the actual value which is in use.

OBJECT-TYPE

This attribute 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 attribute. 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 the WindowFunction MIB object, or a value of 'other' will be reported. Use of 'modern' windowing functions not yet defined will likely be reported as 'other'. 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.

OBJECT-TYPE

This attribute 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 attribute to an unsupported number of averages, an error will be returned.

OBJECT-TYPE

This table provides a list of spectral analysis measurements as performed across a range of center frequencies. The table is capable of representing a full scan of the spectrum.

OBJECT-TYPE

Each row in the docsIf3CmSpectrumAnalysisMeasTable represents the spectral analysis around a single center frequency point in the spectrum.

OBJECT-TYPE

This index indicates the center frequency of the spectral analysis span which is represented by this instance.

OBJECT-TYPE

This attribute provides a list of the spectral amplitudes as measured at the center frequency specified by the Frequency index. The frequency bins are ordered from lowest to highest frequencies covering the frequency span. Information about the center frequency, frequency span, number of bins and resolution bandwidth are included to provide context to the measurement point.

OBJECT-TYPE

This attribute provides the total RF power present in the segment with the center frequency equal to the Frequency index and the span equal to the SegmentFrequencySpan. The value represents the sum of the spectrum power in all of the associated bins. The value is computed by summing power (not dB) values and converting the final sum to TenthdBmV.

OBJECT-TYPE

This table defines Energy Management mode statistics for the CM as reported by the CMTS. For example, such metrics can provide insight into configuration of appropriate EM 1x1 Mode Activity Detection thresholds on the CM and/or to get feedback on how/if the current thresholds are working well or are causing user experience issues.

OBJECT-TYPE

The conceptual row of docsIf3CmtsCmEmStatsTable.

OBJECT-TYPE

This attribute indicates the total time duration, in seconds since registration, the CM identified by docsIf3CmtsCmRegStatusId has been in Energy Management 1x1 mode, as controlled by the DBC-REQ Energy Management 1x1 Mode Indicator TLV.

OBJECT-TYPE

This table defines Energy Management 1x1 mode statistics on the CM to provide insight into configuration of appropriate EM 1x1 Mode Activity Detection thresholds and/or to get feedback on how/if the current thresholds are working well or are causing user experience issues. These statistics are only applicable/valid when the Energy Management 1x1 mode is enabled in the CM.

OBJECT-TYPE

The conceptual row of docsIf3CmEm1x1StatsTable. An instance exist for the CM MAC Domain Interface.

OBJECT-TYPE

This attribute indicates the number of times since registration the CM crossed below the upstream entry bitrate threshold for a number of consecutive seconds equal to or exceeding the upstream entry time threshold.

OBJECT-TYPE

This attribute indicates the number of times since registration the CM crossed below the downstream entry bitrate threshold for a number of consecutive seconds equal to or exceeding the downstream entry time threshold.

OBJECT-TYPE

This attribute indicates the total time duration, in seconds since registration, the CM has been in Energy Management 1x1 mode, as controlled by the DBC-REQ Energy Management 1x1 Mode Indicator TLV. This attribute differs from docsIf3CmEm1x1StatsTotalDurationBelowUsDsThrshlds because it is dependent on effects of the Energy Management Cycle Period, and processing of EM-REQ/EM-RSP messages and DBC messages that specifically indicate entry into or exit from Energy Management 1x1 mode.

OBJECT-TYPE

This attribute indicates the total time duration, in seconds since registration, the CM satisfied upstream conditions for entry into or remaining in Energy Management 1x1 mode.

OBJECT-TYPE

This attribute indicates the total time duration, in seconds since registration, the CM satisfied downstream conditions for entry into or remaining in Energy Management 1x1 mode.

OBJECT-TYPE

This attribute indicates the total time duration, in seconds since registration, the CM, with respect to both upstream and downstream entry and exit thresholds, satisfied conditions for entry into and remaining in Energy Management 1x1 mode. This attribute differs from docsIf3CmEm1x1StatsTotalDuration because it is not dependent on effects of the Energy Management Cycle Period or processing of EM-REQ/EM-RSP messages and DBC messages that specifically indicate entry into or exit from Energy Management 1x1 mode.

OBJECT-TYPE

The UsChExt2 table is optional and defines management extensions for upstream local channels.

OBJECT-TYPE

The conceptual row of docsIf3UsChExt2Table. The index corresponds to a logical upstream channel.

OBJECT-TYPE

This attribute reports the total number of CMs with channels in the CM Transmit Channel Set (TCS) and where each CM's CmtsCmRegStatus::Value has reached a state of 'registrationComplete', 'operational', 'bpiInit', or 'forwardingDisabled'.

OBJECT-TYPE

This attribute reports the target MAP interval for the selected channel.
