The TC400B is a bundle of the half-length, low-profile PCI-2.2compliant
TC400P base card and the TC400M voice processing module. The
TC400B is designed to perform, in dedicated DSP resources, the complex
codec translations for highly compressed audio as would otherwise be
processed by Asterisk® in software on the host CPU.
Asterisk, in software and with Digium® G.729a licensing, is capable of
transforming the G.729a codec into other codecs for the purposes of
call origination or termination, bridging disparate calls or VoIP to
TDM connectivity. These transformations in software are very expensive,
in terms of MIPS, and require a substantial amount of CPU time to
accomplish. The TC400B not only relieves the CPU of this duty, freeing
it up to handle other tasks or to complete additional call processing;
but also provides Asterisk with the capability of transforming G.723.1
compressed audio into other formats, a capability not previously
The TC400B decompresses G.729a (8.0kbit) or G.723.1 (5.3kbit) into
μ-law or a-law; or, compresses u-law or a-law into G.729a (8.0kbit) or
G.723.1 (5.3kbit). The TC400B is rated to handle up to 120
bi-directional G.729a transformations or 92 bi-directional G.723.1
transformations. The TC400B does not require additional licensing fees
for the use of these codecs nor does it require the registration
process associated with Digium’s software-based G.729a codec licensing.
Please note this does not include a low profile bracket. See related items if you require a low profile bracket.
