Sangoma A400 PCI Express Telephony Card Configurator

The Sangoma A400 PCIe voice card delivers superior audio quality in a 2U card that expands from two to twenty-four ports using a single PCI Express interface slot.

Sangoma A400 Analog Telephony Card Overview:

For optimum echo-cancelled voice quality and enhancement, choose the A400D Model with DSP Daughterboard 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 PCIe 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 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.

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

Optional DSP Echo Canceller Daughterboard on the A200D

  • G.168-2002 echo cancellation in hardware
  • 1024 taps/128ms tail per channel on all channel densities
  • DTMF decoding and tone recognition
  • Voice quality enhancement: music protection, acoustic echo control and adaptive noise reduction
  • No CPU load as a result of echo cancellation
  • Does not increase the physical size of the card, and no additional slot is required


The A400 consists of a Remora™ daughterboard mounted on the AFT PCIe card. The Remora™ card has six 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 one additional Remora™ daughterboard can be mounted in empty slot positions beside the A400 assembly and connected to the A400 Base Card by a backplane bus connector.

Each 12-port A400 Remora™ card has a robust DB25 connection to an included standard 12-line, colour-coded telephone cable that is ready for hardwiring into a punch block at the PSTN connection.
