Description
For optimum echo-cancelled voice quality and enhancement choose the A200D Model with OctasicDSP 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, and 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.

Get the Fax on Sangoma Hardware
- With Sangoma, there is no need for a separate analog line to run your fax machine.
- Using T1/E1 passthrough with Sangoma analog cards, there are no clock slips, buffer overruns, or transmit underruns that cause missed lines, blank sheets, and missed pages when faxing.
- Sangoma A200 and A400 cards synchronize perfectly with digital T1/E1 cards and the PSTN atomic clock for error-free fax and modem passthrough and superior voice quality over T1 and E1 lines.

Architecture
The A200 consists of a Remora daughterboard mounted on the AFTPCI card. The Remora card has two sockets each of which can accept a FXO-2 or FXS-2 module. Each FXO-2 or FXS-2 module supports two FXO or FXS lines, respectively.
Up to five additional Remora daughterboards can be mounted in empty slot positions beside the A200 assembly, connected to the A200 by a backplane bus connector.
