The TE133 and TE134 cards support industry standard telephony protocols, including Primary Rate ISDN (both North American and Euro Standard) protocol families for voice. Both line-side and trunk-side interfaces are supported, as well as advanced call features. Octasic-based hardware echo cancellation is built in to the cards, which removes the task of echo cancellation from the systems CPU and increases overall system performance and call quality.
Digium cards are compatible with all versions of Asterisk using the DAHDI driver framework. Asterisk and DAHDI are available for free from the Asterisk.org website. All cards include a five (5) year warranty and are eligibile for Digium's no-risk ESP guarantee.
