Built Exclusively For High-Density Asterisk® Applications

That Require High-Performance, Cost-Effective Digital Connectivity.

Key Features

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 available 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 octal span digital 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.

8 T1 / E1 Spans
Up to 240 concurrent calls per card
