The sandwich DSP card on the "d" model features Octasic's certified carrier-grade algorithms providing carrier grade echo cancellation and Voice Quality Enhancement (VQE) functions. Supporting 32-672 channels G.168-2002 echo cancellation, a minimum of 1024 taps for a 128ms tail/channel on all channel densities, the system also supports Octasic music protection, acoustic echo control and adaptive noise reduction. The "d" model also features on-board DTMF decoding and tone recognition.

The A104 is the, quad port version of Sangoma's range of Advanced, Flexible Telecommunications (AFT) hardware designed for optimum support of voice and data over T1, E1 and J1.

The A104 provides full speed 132 Mbps PCI bus transfer with FPGA and DSP based processing to unload the host CPU in demanding environments such as soft PBX/IVR voice applications. Compatible with both the 3.3v and 5v PCI bus, A104 cards operate in all commercially available motherboards sharing IRQs properly with themselves and all other PCI compatible devices, so you never have to worry about hardware compatibility issues.

Like all the Sangoma AFT Series, the A104 is field upgradeable to take advantage of the hardware and software improvements as they become available.
