Digium TC400B/TCE400B Voice Compression Card is a bundle of the half-length, low-profile PCI-2.2/PCIe compliant TC400P/TCE400P base card and the TC400M voice processing module. The TC400B/TCE400B is designed to handle, in dedicated DSP resources, the complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software.
The TC400B/TCE400B decompresses G.729a (8.0kbit) or G.723.1 (5.3kbit/6.0kbit) into G.711 u-law or a-law; or compresses G.711 u-law or a-law into G.729a (8.0kbit) or G.723.1 (5.3kbit). The TCE400B is rated to handle up to 120 bi-directional G.729a transformations or 92 bi-directional G.723.1 transformations. The TCE400B does 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.

- TC400M Voice Processing Module
- TC400P - Half-Length Low-Profile PCI 2.2+ 3.3/5.0V Card or TCE400P - Half-Length Low-Profile PCI-Express x1 Card
