The TCE400B is a bundle of the half-length, low-profile PCI-
Express x1 TCE400P base card and the TC400M voice
processing module. The TC400B is a bundle of the half-length,
low-profile PCI 3.3/5.0V TC400P base card and the TC400M
voice processing module. The TCE400B and TC400B are
designed to handle, in dedicated DSP resources, the complex
codec translations for highly compressed audio as would
otherwise be processed by Asterisk in software.
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 TCE400B and TC400B
not only relieve the CPU of this duty, freeing it up to handle other
tasks or complete additional call processing, but also provide
Asterisk with the capability of bridging G.723.1 compressed audio
into other formats, a capability not otherwise possible.
The TCE400B and TC400B decompress G.729a (8.0kbit) or
G.723.1 (5.3kbit/6.0kbit) into G.711 u-law or a-law and compress
G.711 u-law or a-law into G.729a (8.0kbit) or G.723.1 (5.3kbit).
The TCE400B and TC400B are rated to handle up to 120
bi-directional G.729a-only transformations or 92 bi-directional
mixed-mode G.729a/G.723.1 transformations. The TCE400B
and TC400B do not require additional licensing fees for the
use of these codecs nor does it require the registration process
association with Digium’s software-based G.729a codec licensing.
