Transcoding Cards

IP telephony applications commonly require the use of multiple voice codecs, used to digitally compress voice signals and save on bandwidth. Voice signals from the PSTN come in the form of the G.711 codec, but the VoIP terminal equipment and networks can support a variety of different voice codecs, such as G.729. The VoIP infrastructure needs the capability to mediate between endpoints supporting different codecs.

Our Transcoding Cards are designed to handle complex codec translation, using dedicated DSP resources, which would otherwise be processed by host CPU in software. This card greatly reduces the MIPS or CPU consumption, so that it can be used for handling other tasks.

Our Transcoding Cards are available in PCI and PCI Express form factors, converts simultaneous
channels of transcoding from one type of codec (e.g. G.711) to another (e.g. G.729), without
affecting latency or using up precious host CPU resources.
