Sangoma A400 Analog Card Series

The A400 Series of analog voice cards deliver superior audio quality in a 2U card that expands from two to twenty-four ports using a single interface slot.

For optimum echo-cancelled voice quality and enhancement, choose the A400D Model with Octasic^® DSPDaughterboard Hardware Echo Canceller. One DSP echo canceller on the A400D Base Card will support Telco-grade hardware echo cancellation on all channels, up to the card's maximum configuration in 24 ports with no additional CPU load. To reach this configuration, simply add additional Remora^™ cards to any base card in the A400 Series.

A single PCI or PCI Express slot hosts the connection and ensures common synchronous clocking for all channels. Like all the cards in the award-winning Sangoma AFT Series Product Line, the A400 and Remora^™ system's architecture is shared with Sangoma's A101, A102, A104, A108 and A200 cards, ensuring common 3.3 V or 5 V, high performance, universal PCI or PCI Express compatibility, and crash-proof field upgradable firmware to take advantage of enhancements, as they become available.

Sangoma cards guarantee error-free faxing and click-free audio on analog-digital links.
