Overview The TC400 Series cards are a bundle of the half-length, low-profile TC400P (PCI) or TCE400 (PCI-E) base card and the TC400M voice processing module. The TC400 Series cards 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.
Chapter 1: Overview they require the registration process associated with Digium's software- based G.729a codec licensing. Features: 120 channels of bi-directional G.729a (8 Kbit) transcoding 92 channels of bi-directional G.723.1 (5.3 Kbit and 6.3 Kbit) transcoding Figure 1: Sample Telco Application Digium, Inc.
It can also be built out as the heart of a media gateway, bridging the legacy PSTN to the expanding world of IP telephony. Asterisk’s modular architecture allows it to convert between a wide range of communications protocols and media codecs. Digium, Inc. Page 14...

(e.g. ulimit -n [limit] ulimit -n 32768 Q: Does my card take 1000 interrupts per second like my other Digium cards? A: A TC400 Series card only takes interrupts when it is in an active transcoding state, and will not pull interrupts when it is idling. This is different behavior than Digium analog and digital interface cards exhibit.
