Digium TE820F 8-Port Digital PCIe card T1/E1/J1/PRI

Digium TE820F 8-Port Digital PCIe card T1/E1/J1/PRI

Digium 1TE820F 8-Port T1/E1/J1 PCIe Card

The Digium 1TE820F is an eight-port digital interface card. It can handle up to 8 T1, E1 or J1 connections. That's up to 192 concurrent calls in T1 or J1 mode, or 240 calls in E1 mode, making it the highest-density card made for use with Asterisk. The TE820 digital card comes in a PCI Express form factor and is without onboard echo cancellation. You can add on the VPMOCT256, an echo cancellation module that can handle up to 256 concurrent calls, at the time of installation or at a later time in the field.

Digium TE820 Overview

Digium’s TE820 Octal-Span digital card is built exclusively for high-density Asterisk® applications that require high performance and 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 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.
