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 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 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.

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/DE
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
Wiring Connections
The A400 and Remora™ cards incorporate 4-pin RJ11/4 narrow jacks, such as those used in telephone handsets
Each Sangoma A200 Card is shipped with four 2 m cables terminating in a narrow RJ11/4 plug at one end and a telephone-standard RJ11/6 plug at the other
To hardwire the A200 system, you can purchase a kit of 12 RJ11/4 plugs and a crimping tool, sold separately
Operating Systems
Windows® 2003, Windows® XP, Windows® Server 2008, Windows® Vista, Windows® 7
Linux (all versions, releases and distributions from 1.0 up)
Architecture
The A400 consists of a Remora™ daughterboard mounted on the AFT PCI 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.
