dspPad

This object allows you to specify the characteristics of the DSP packet assembly and disassembly (PAD) resources in the SBC 5000 series.

Exists on Condition (/system/sbcPersonality/role !='ssbc') and (/system/sbcPersonality/role !='slb')

Configuration

ParameterPresenceTypeDefaultDescription
jitterEvalPeriodOuint321000 Time period to decide when to periodically evaluate playout occupancy (in milliseconds).
jitterMinOccThshOuint3220 If occupancy falls below this threshold for some time period we advance the playout time (in milliseconds).
rtpDtmfRelayOuint32100 RTP Payload type to be received as DTMF relay during compressed calls.
sidMinTimeOuint32200 Minimum time (in milliseconds) between silence packets.
sidMaxTimeOuint322000 Maximum time (in milliseconds) between silence packets. Must be larger than minimum time between silence packets.
sidHangoverTimeOuint32300 Minimum time (in milliseconds) after DSP detects speaker going inactive before sending silence packets.
sidMinNoiseFloorOuint3260 Minimum noise floor (in -dBm). If energy level is below this it will be considered as silence. Configuration range is between -62dBm -24dBm.
sidMaxNoiseFloorOuint3248 Maximum noise floor (in -dBm). If the energy level is above this it will be considered as speech. Configuration range is between -62dBm -24dBm.
comfortEnergyOuint3256 Initial estimate (in -dBm) to be used for generating comfort noise. It is used when no silence packets are received to generate comfort noise. Configuration range is between -90dBm and -35dBm.
universalCompressionThresholdOuint3290 Percentage Threshold crossing value for Universal Compression resources. When this threshold is reached an event will be generated if universalCompressionThresholdState is enabled.
universalCompressionThresholdStateOenumerationenabled State of Universal Compression Threshold Event. An event will be generated only if state is enabled.
playoutTimeseriesPeriodOuint3220000 Duration of one period of the RTP playout buffer loss timeseries statistic. This statistic is used only when an RTP stream is terminated (it does not operate in a Packet Monitor channel type). Units: milliseconds (will be converted to 10 msec increments)
playoutTimeseriesThreshold0Ouint320 Threshold #0 for generation of the playout loss timeseries statistic. The first quantization level is <= this threshold. The set of three thresholds specified here are used for all channel instances. Units: milliseconds (will be converted to 10 msec increments) Default: 0 (0.0 sec, 0% of playoutTimeseriesPerdiod)
playoutTimeseriesThreshold1Ouint32200 Threshold #1 for generation of the playout loss timeseries statistic. The second quantization level is: Threshold #0 < #Interpolations <= Threshold #1 Units: milliseconds (will be converted to 10 msec increments) Default: 200 (0.2 sec, 1% of playoutTimeseriesPerdiod)
playoutTimeseriesThreshold2Ouint32600 Threshold #2 for generation of the playout loss timeseries statistic. The third quantization level is: Threshold #1 < #Interpolations <= Threshold #2 Units: milliseconds (will be converted to 10 msec increments) Default: 600 (0.6 sec, 3% of playoutTimeseriesPerdiod)
toneThresholdOuint3290 Percentage Threshold crossing value for tone resources. When this threshold is reached an event will be generated if toneThresholdState is enabled.
toneThresholdStateOenumerationenabled State of Tone Threshold Event. An event will be generated only if state is enabled.
audioTxDuring2833Oenumerationenabled State of Audio Transmit During 2833. Parameter that allows the user to inhibit the transmission of audio packets during the period lasting from the start of a transmitted RFC4733 event to the end of the transmitted RFC4733 event.
highPriorityCompressionReservationOuint320 Percentage of compression resources reserved for high priority calls.
highPriorityToneReservationOuint320 Percentage of tone resources reserved for high priority calls.
