Use this profile to define the standard and custom codec mix profile configuration to use for a given SWe Traffic Profile. This profile includes two the following default profiles:

  • G711_20ms: using Using 100% G711 (20 ms) calls.
  • G711_G729_20ms: using Using 50% of G729AB (20 ms) and 50% G711 (20ms).
  • G7112G711 - The percentage value of this codec indicates the proportion of total number of sessions designated for pure G711 transcoding (G711-G711). This is applicable for Hybrid Transcoding and CPU transcoding solutions.
  • T38

<profile name> – Enter a unique SWe Codec Mix Profile name or one of the default profiles:
  • G711_20ms – configured Configured with 100% G.711 (20 ms) calls.
  • G711_G729_20ms – configured Configured with 50% G.729AB (20 ms) and 50% G.711 (20 ms).
  • G7112G711 - The percentage value of this codec indicates the proportion of total number of sessions designated for pure G711 transcoding (G711-G711). This is applicable for Hybrid Transcoding and CPU transcoding solutions.
  • T38
The SWe Codec Mix Profile iis is attachable to either the passthroughCodecProfile or transcodingCodecProfile objects of the SWe Traffic Profile.
NOTENote:
  • The SBC SWe supports up to 20 Codec Mix Profiles. To create additional profiles, delete any inactive custom profiles.
  • DSP-based tone detection is available only on GPU - I-SBC profiles.
  • The following CPU and GPU codecs are supported for SBC SWe on Openstack and KVM:
    • GPU + CPU codecs : AMR-NB, AMR-WB, EVRC, EVRCB, G729, G722, G711
    • CPU only codecs :  G723, G726, G7221, ILBC, OPUS, SILK_8, SILK_16, EVS, G7112G711, T38
  • You can provision CPU codecs in the codec profile and associate it with the GPU traffic profile; however, you must provision at least one GPU codec in the sweCodecMixProfile.
<codec>N/AEnter the codec used by this Codec Mix Profile. Refer to Audio Codecs for the list of supported codecs.
<ptime value>N/A
Select a packetization time value representing 10 ms, 20 ms, 30 ms, 40 ms, 60 ms, 80ms, and 100ms:
  • p10
  • p20
  • p30
  • p40
  • p60
  • p80
  • p100
Note: For SBC SWe Cloud 8.1, ptime values p80 and p100 are not tested.
percentage10.00 -100.00
<% value> – The percentage distribution allocated for the codec mix.
Note:
  • The sum of all percentage entries of all columns in any row of the transcoding profile table must equal 100.
  • Floating point values are supported as percentage values; the allowed percentage range is 0.00-100.00.
  • The percentage value for G7112G711 is used for estimating transcode and bandwidth cost.
  • The percentage value for G711 is not used for estimating transcode cost, but is used for bandwidth calculation of PXPAD scenarios.
  • The percentage value for G711 cannot be greater than the percentage value of non-G711 codecs.
Command Example
In the following example, a custom Codec Mix profile is created ensuring the percentage distribution of the three entries equals 100%.
 Code Block
set system sweCodecMixProfile customCodecMix g723 p20 percentage 50
set system sweCodecMixProfile customCodecMix g711 p20 percentage 30
set system sweCodecMixProfile customCodecMix g729 p10 percentage 20

Best Practice
Ribbon recommends monitoring of the status of codec channel capacities for codecs provisioned on GPU (on a per GPU device basis), as well as on CPU. 
  • To display the status of codec channel capacities for codecs provisioned on GPU, on a per GPU device basis, execute the following existing command:
     Code Block
    > show table system gpuTranscodeStatus
  • Similarly, to display the status of codec channel capacities for codecs provisioned on CPU, execute the following existing command:
     Code Block
    > show table system cpuTranscodeStatus
