Description
Sangoma’s TE820 Octal-Span digital card is designed specifically for high-density Asterisk® applications that require high-performance and low-cost digital connectivity. The Sangoma TE 820 has eight software-selectable digital telephony interfaces that can support up to 192 channels (in T1/J1 mode) or 240 channels (in E1 mode) — the most port density available for Asterisk use on a single card. The Sangoma TE 820 integrates traditional telephony systems with Voice over IP (VoIP) technologies at the market’s lowest per-port price. The TE820 card supports industry standard telephony protocols such as multiple Primary Rate ISDN variants. For maximum flexibility, each span can be configured as either a CPE or a network. The optional VPMOCT256 hardware echo cancellation module, based on the industry-leading Octasic chipset, relieves the CPU of the task of echo cancellation, improving overall system performance and call quality.
The TE820 card is fully compatible with existing software applications and seamlessly integrates with Sangoma’s Asterisk software. The open-source drivers for Sangoma cards include an application programming interface (API) for developing custom applications. Sangoma hardware and Asterisk software collaborate to provide a low-cost platform for developing a wide range of communications solutions, including PBX systems and VoIP gateways, as well as call centers and full unified communications suites. Sangoma solutions are assisting in the development of a new generation of global communications.
