| dcxFftObjects OBJECT-IDENTITY | 1.3.6.1.4.1.4115.1.4.5.1.1 | |||
| dcxFftUpstreamChannelTable OBJECT-TYPE Arris CMTS FFT upstream channel configuration table. An entry in this table exists for each ifEntry with an ifType of docsCableUpstreamInterface (129) that supports FFT collection and reporting. | 1.3.6.1.4.1.4115.1.4.5.1.1.1 | not-accessible | current | |
| dcxFftUpstreamChannelEntry OBJECT-TYPE Arris FFT upstream channel entry. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1 | not-accessible | current | |
| dcxFftSize OBJECT-TYPE Number of samples to be collected for FFT. Valid values are 256, 512, 1024, 2048. The FFT payload size will be the number of samples multiplied by the number of bytes per sample as determined by dcxFftOutputFormat. The duration of the FFT sample will be the number of samples divided by the sample rate as determined by dcxFftSampleRate. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.1 | Unsigned32 | read-write | current |
| dcxFftSampleRate OBJECT-TYPE FFT sample rate based on the input source to the FFT. The input to the FFT can be the ADC output, the ADC output followed by a down-mixer and half-band filter, the ADC output followed by a down-mixer and quarter-band filter, or the received channel's Nyquist filter output. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.2 | INTEGER {adcRate(1), halfAdcRate(2), quarterAdcRate(3), quadrupleSymbolRate(4)} | read-write | current |
| dcxFftCentreFrequency OBJECT-TYPE FFT centre frequency. This object is used only if dcxFftSampleRate is set to halfAdcRate or quarterAdcRate to set the down-mixer frequency. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.3 | Integer32 | read-write | current |
| dcxFftWindowing OBJECT-TYPE Set the frequency-domain windowing filter. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.4 | INTEGER {rectangular(1), hanning(2), hamming(3), blackman(4), blackmanHarris(5)} | read-write | current |
| dcxFftLogAveragingTimeConstant OBJECT-TYPE Time averaging constant exponent, M. Constant is 2^M. Setting this object to zero disables averaging. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.5 | Unsigned32 (0..7) | read-write | current |
| dcxFftOutputFormat OBJECT-TYPE FFT processor output format. Format can be i. raw complex time-domain I/Q format ii. FFT data in I/Q format iii. FFT data in power format iv. FFT data in amplitude format. The sample sizes are 4 bytes (i. - iii.) and 2 bytes (iv.) | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.6 | INTEGER {raw(1), fftIQ(2), fftPower(3), fftAmplitude(4)} | read-write | current |
| dcxFftOperatingMode OBJECT-TYPE Operating mode of FFT process. Determines whether the FFT measurement takes place while no CMs are transmitting (measuring noise floor), during a CM burst, or by periodically sampling the spectrum without regard to scheduling of the upstream. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.7 | INTEGER {baseSpectrum(1), burstSpectrum(2), periodicSpectrum(3)} | read-write | current |
| dcxFftIdleInterval OBJECT-TYPE Interval in microseconds between consecutive FFT triggers when dcxFftOperatingMode is baseSpectrum or periodicSpectrum. This object is not used if dcxFftOperatingMode is set to burstSpectrum or if dcxFftTriggerCount is 1. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.8 | Unsigned32 | read-write | current |
| dcxFftBurstSid OBJECT-TYPE SID on which to trigger the FFT process. This object is used only if dcxFftOperatingMode is set to burstSpectrum. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.9 | Unsigned32 (0..16383) | read-write | current |
| dcxFftBurstIUC OBJECT-TYPE IUC type on which to trigger the FFT process. This object is used only if dcxFftOperatingMode is set to burstSpectrum or periodicSpectrum. A value of 0 means trigger on any IUC type. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.10 | INTEGER (0..15) | read-write | current |
| dcxFftLogicalChannel OBJECT-TYPE Logical channel on which to trigger the FFT process. This object is used only if dcxFftOperatingMode is set to periodicSpectrum. A value of -1 means trigger on any logical channel. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.11 | INTEGER (-1..3) | read-write | current |
| dcxFftTriggerCount OBJECT-TYPE Number of times to trigger FFT when dcxFftEnable and dcxFftApplyConfig are set to true. Set this object to zero to trigger FFT continuously. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.12 | Unsigned32 | read-write | current |
| dcxFftEnable OBJECT-TYPE Set to true to enable FFT on this channel. Set to false to disable. Setting will take effect when dcxFftApplyConfig is set to true | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.13 | TruthValue | read-write | current |
| dcxFftApplyConfig OBJECT-TYPE Set to true to trigger an FFT process with configuration determined by the other objects in this group. An SNMP GET of this object will always return false | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.14 | TruthValue | read-write | current |
| dcxFftInProgress OBJECT-TYPE This object will return true if an FFT process is currently in progress (having been started by a SET to dcxFftApplyConfig) for this upstream channel. Returns false otherwise | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.15 | TruthValue | read-only | current |
| dcxFftCurrentTriggers OBJECT-TYPE Number of FFT triggers since the last FFT process was started. | 1.3.6.1.4.1.4115.1.4.5.1.1.1.1.16 | Unsigned32 | read-only | current |

| dcxFftPayloadEntry OBJECT-TYPE Arris CMTS FFT upstream channel payload entry. Multiple entries in this table exist for each ifEntry with an ifType of docsCableUpstreamInterface (129) that supports the FFT collection and currently has FFT data to report. | 1.3.6.1.4.1.4115.1.4.5.1.1.2.1 | not-accessible | current | |
| dcxFftPayloadIndex OBJECT-TYPE An identifier for the 256-byte buffer available at the dcxFftPayloadData object. | 1.3.6.1.4.1.4115.1.4.5.1.1.2.1.1 | Unsigned32 | not-accessible | current |
