Digium’s new TE131 and TE132 single span digital cards are the latest additions to the Telephony Card family. The TE131 and TE132 design utilizes state of the art technologies to support T1/E1/PRI environments that require a high-performance, cost effective digital telephony interface card that does not require echo cancellation. The TE131 and TE132 have the ability to create a seamless network, interconnecting traditional telephony systems with Voice over IP technologies. 

The TE131 and TE132 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.  Users requiring echo cancellation should instead look to Digium's TE133 and TE134 cards.

The TE131 and TE132 cards are fully compatible with existing software applications and is fully integrated with Digium’s Asterisk® software. The open source drivers for these cards support an application programming interface (API) for custom application development.

From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications.
