Quick Overview

The TE820 supports up to 192 channels in T1/J1 mode or 240 in E1 mode.

Digium TE820 Information:

The TE820 supports ISTPs, including several variants of Primary Rate ISDN, and each span can be configured as either CPE or network for optimum adaptability. With the optional VPMOCT256 hardware echo cancellation module, the CPU is not burdened with echo cancellation, improving call quality and overall system performance.

This 8 port T1 card is fully compatible with current software applications and is completely integrated with Digium's Asterisk software. Custom application development is facilitated with the open source drivers for Digium cards, which support an application programming interface (API). Whether your business telephony platform includes a PBX system, VoIP gateways, call centers or complete unified communications suites, the combination of Digium hardware and Asterisk software provides a cost-sensitive foundation.
