Digium 1TE133F Single Span Digital T1; E1; J1 And PRI PCI-Express Card With Hardware Echo Cancellation

Digium's new TE133 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 have 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 cards are compatible with all versions of Asterisk using the DAHDI driver framework. website.

Single span digital cards are perfect for building Asterisk solutions with direct connections to the phone network or legacy equipment. Common applications include:.

• Direct PSTN connections for office phone systems
