Transcoding Support

Based on the transcoding resources available, which vary by platform, different codecs may be transcoded from- and to-.

Platform	Supported Codecs (by way of codec-policy in the add-on-egress parameter)
Acme Packet physical platforms Hardware-based transcoding for virtual platforms (PCIe Media Accelerator) The Acme Packet 4900 does not support 40 and 60 packetization times for the EVS codec.

Note that the pooled transcoding feature on the VNF uses external transcoding ESBC, as defined in "Co-Product Support," for supported ESBC for the Transcoding-SBC (T-SBC) role.

^Footnote 1Hardware-based EVS SWB and EVS FB transcoding is supported for decode-only.

TCM3 and System Software Compatibility

As of April 2023, Oracle has begun supporting new memory components for the TCM3. These components are dependent on ESBC software version. Newer Oracle software releases, starting with SCz9.2.0p1, provide you with multiple means of verifying TCM3 memory compatibility. Software versions prior to SCz9.2.0p1 do not operate properly with this new memory, but does allow the TCM3 cards to boot. Furthermore, system behavior when you use older software with this new memory is unpredictable.

If you need to verify the hardware you have, use the show-prom-info all command to display the TCU card part number. The applicable part numbers include:

TCM3 card with old memory—8202681
TCM3 card with new memory—8213881

See Minimum TCM3 Versions on the Acme Packet 3950/4900 in the Transcoding chapter for explanation about verifying TCM3 memory compatibility with this ESBC software release.
