Digium Digital Telephony Cards

Single Span

Digium’s new TE131, TE132, TE133 and TE134 single span digital cards are the latest additions to the Telephony Card family. The TE13x design utilizes state of the art technologies to support T1/E1/PRI environments that require a high-performance, cost effective digital telephony interface card. The TE13x family of cards has the ability to create a seamless network, interconnecting traditional telephony systems with Voice over IP technologies.

The TE13x family of 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. TE133 and TE134 model cards feature Octasic-based hardware echo cancellation that is built in to the cards, removing the task of echo cancellation from the systems CPU and increasing overall system performance and call quality. TE131 and TE132 model cards are for environments that do not require hardware-based echo cancellation, instead relying only on software echo cancellation.

Digium Digital Telephony Cards

Dual Span

Digium's dual span digital interface cards support 48 (T1 / J1) or 60 (E1) connections to PSTN trunks over two spans (digital circuits). Built exclusively for use with Asterisk and Asterisk-based communications systems, the dual span cards provide the best value in digital connectivity.

Dual span digital cards are available in PCI and PCI-Express form factors. All dual span models can be combined with an Octasic DSP-based echo cancellation module from Digium to provide effective hardware echo cancellation across all channels.

Note: The TE210P model supports a 3.3v PCI slot only - typically available on newer server motherboards and in 64-bit PCI bus architectures. The TE205P is for use only with a 5.0 volt PCI slot.
