TE820 Octal-Span Digital Card
Version 1
.0/5 October 20

Digium’s TE820 Octal-Span digital card is built exclusively
for high-density Asterisk
®
 applications that require high-
performance, cost effective digital connectivity. The TE820 
includes eight independently software-selectable digital telephony 
interfaces, supporting up to 192 channels (in T1/J1 mode) or 240 
channels (in E1 mode) — the highest single-card port density avail-
able for use with Asterisk. The TE820 seamlessly interconnects 
traditional telephony systems with Voice over IP (VoIP) technologies 
at the lowest per-port price on the market today.
The TE820 card supports industry standard telephony protocols, 
including multiple variants of Primary Rate ISDN. Each span can 
be configured as either CPE or network for optimal flexibility. 
The optional VPMOCT256 hardware echo cancellation module, 
based on the industry-leading Octasic chipset, offloads the task 
of echo cancellation from the CPU, increasing overall system 
performance and call quality.
The TE820 card has been designed to be fully compatible 
with existing software applications and is fully integrated with 
Digium’s Asterisk software. The open source drivers for Digium 
cards support an application programming interface (API) for 
custom application development. The combination of Digium 
hardware and Asterisk software provides a cost effective platform 
for building numerous communications solutions, from PBX 
system and VoIP gateways to call centers and complete unified 
communications suites. Digium solutions are paving the way for 
a new generation of worldwide communications.
