The TC400B is a bundle of the half-length low-profile PCI-2.2 compliant TC400P base card and the TC400M voice processing module. The TC400B 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. 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. 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 bridging G.723.1 compressed audio into other formats a capability not previously possible.The...

Digium AEX822B (2 FXS/2 FXO) PCI-e Card The AEX800 is a half-length PCI-Express 1.0-compliant, 8 port analog interface card. It supports combinations of station and/or trunk/line modules for a total of eight (8) interfaces. Like our PCI-based TDM800P, the AEX800 provides an industry first with 8 standard two-wire, RJ-11 interfaces on a single card bracket. This eliminates the need for multiple brackets, external dongles, or splitters. In doing so, the AEX800 reduces part complexity, cable clutter, and points of failure. The AEX800 contains two module banks. Each bank supports up to four analog interfaces and may be filled either with one standard Digium quad station (S400M) or line/trunk (X400M) analog module, or up to two standard Digium single analog station (S110M) or line/trunk...
