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 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.
Single span digital cards are perfect for building Asterisk solutions with direct connections to the phone network or legacy equipment. Common applications include:
|Dimensions||12.7 x 6.7 cm|
|Bus Type||PCI-E 1.0+|
|No. Of Ports||4 ports|
|Industry Standard||RJ-45 port|
|Form Factors||PCI and PCI Express|
|Protocol Support Includes||ISDN PRI, Robbed-Bit, CAS|
Digium's quad span digital interface cards support 96 (T1 / J1) or 120 (E1) connections to PSTN trunks over four spans (digital circuits). Built exclusively for use with Asterisk and Asterisk-based communications systems, the quad span digital cards provide the best value in digital connectivity.
Quad span digital cards are available in PCI and PCI-Express form factors. All quad span models can be combined with an Octasic DSP-based echo cancellation module from Digium to provide effective hardware echo cancellation across all channels.
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 eligible for Digium's Exceptional Satisfaction Program (ESP) risk-free Quality Guarantee.
