Note

This object is accessible only in SBC SWe environments.

Use this window to view and create Swe codec mix profiles for use in traffic profiles. A codec mix profile can be attached as either the Pass-through Codec Profile or Transcoding Codec Profile in a traffic profile.

This profile includes the following default profiles:

  • G711_20ms: Using 100% G711 (20 ms) calls.
  • G711_G729_20ms: 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). 
  • T38

To View SWe Codec Mix Profiles

On the SBC main screen, go to All > System > Swe Codec Mix Profile. The Swe Codec Mix Profile window opens.

To Create a SWe Codec Mix Profile

On the Swe Codec Mix profile window:

  1. Click New Swe Codec Mix Profile. The Create New Swe Codec Mix Profile window opens.

  2. Use the following table to add codec mix profile entries and click Save. If necessary, add additional entries until the percentages of the entries belonging to the same profile (having the same name) equal 100. You can have a maximum of 20 entries in the table.

    ParameterDescription

    Codec Mix Profile Name

    		The codec mix profile name. Enter a unique SWe Codec Mix Profile name or one of the default profiles:
    • G711_20ms – Configured with 100% G.711 (20 ms) calls.
    • G711_G729_20ms – 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). 
    • T38

    The SWe Codec Mix Profile is attachable to either the Passthrough Codec Profile or Transcoding Codec Profile objects of the SWe Traffic Profile.

    Note:

    • 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 and CPU codecs : AMR-NB, AMR-WB, EVRC, EVRCB, EVS, G729, G722, OPUS
      • CPU only codecs :  G723, G726, G7221, ILBC, SILK_8, SILK_16, G7112G711, T38, G711
    • 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

    		A codec name. Refer to Audio Codecs for the list of supported codecs.
    Ptime

    Packetization time for the codec in milliseconds.

    • p10
    • p20
    • p30
    • p40
    • p50
    • p60
    • p80
    • p100

    Note: For SBC SWe Cloud 8.1, ptime values p80 and p100 are not tested.

    Percentage

    The percentage allocated for the codec within the profile.

    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.
Note

With dynamic GPU resource management, the sweTrafficProfiles does not enforce any hard coded per-codec limit. You must still configure the codec percentage in sweCodecMixProfile since this configuration acts as an input for the functional partitioning of VCPUs of the instance.

This feature does not affect the codec channel capacities in a non-GPU accelerated SWe (CPU-based SWe).

To Edit a Codec Mix Profile Entry

Standard codec mix profile entries cannot be edited. You can edit a custom codec mix profile entry.

On the Swe Codec Mix profile window:

  1. Click to select the radio button adjacent to the profile entry you want to edit. The Edit Selected Swe Codec Mix Profile window opens.
  2. Edit the Percentage value and Click Save.

To Delete a Codec Mix Profile Entry

Standard codec mix profile entries cannot be deleted. You can delete a custom codec mix profile entry that is not currently in use.

On the Swe Codec Mix profile window:

  1. Click to select the radio button adjacent to the profile entry you want to delete.
  2. Confirm the deletion when prompted.
