The TC400P provides hardware trans coding of VoIP codecs;
decreasing Asterisk's work load and providing improved CPU
efficiency and an increase in channel density over a
software-only solution. The TC400P provides Asterisk with
full trans coding support and hardware acceleration for the
G.723.1 and G.729A codecs.
The TE415P improve upon Digium's existing TE411P
and TE406P. These premium interface cards provide
carrier-grade echo cancellation, Voice Quality Enhancement (VQE),
DTMF decoding, and tone recognition. Both cards minimize
loads on the processor and PCI bus, and are designed to
perform in the most difficult environments. The TE415P support 128ms of G.168 (2002)-compliant echo
cancellation across their entire 128 channels.
Digium designed these solutions to be fully compatible with
existing software applications and is completely integrated
with the Asterisk platform. Additionally, the open source
driver supports an API interface for custom application
development. All new solutions support industry standard
telephony and data protocols, including Primary Rate ISDN
(both North American and Standard Euro) protocol families
for voice, PPP, Cisco, HDLC and Frame Relay data modes.
