Sangoma A200 Information:


The A200 Series of Analog Voice Cards deliver superior audio quality in a compact 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 A200D Model with DSP daughterboard Hardware Echo Canceller. One DSP echo canceller on the A200D 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 A200 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 A200 and Remora system's architecture is shared with Sangoma's A101, A102, A104, A108 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 soon they become available.


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