VoIP Transcoding PCI-Express x1 card for 120 G.729a or 92 mixed channels of G.729a/G.723.1. The TCE400B PCI-Express is a dedicated codec translation card supporting G.729A and G.723.1. This is a great card for building gateways or for large enterprise environments. The TCE400B is a bundle of the half-length, low-profile PCI-Express x1 TCE400P base card and the TC400M voice processing module. The 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.
