Sangoma A400 with 2–24 Port Expandable Analog Voice Card is the high density version of Sangoma’s popular A200 model.

Sangoma 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 Sangoma A400D Model with DSP Daughtercard Hardware Echo Canceller. One DSP echo canceller on Sangoma A400D base card will support Telco-grade hardwareecho 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™ card to any base card in Sangoma A400 Series. A singlePCI 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.
