Sangoma A104D Quad T1/E1 PCI Card with Onboard Hardware DTMF Decoding and Echo Cancellation with PCIx Bus

The Sangoma A104 is an updated, 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 AFT card supports four T1/E1 or fractional T1/E1 data streams.

Based on bus mastering PCI technology supported by a ring-buffer DMA architecture, the A104U provides full speed 132 Mbps PCI bus transfer with minimal real-time processor load and fully supported interrupt sharing. This provides optimal performance in demanding environments such as soft PBX/IVR voice applications.

Sangoma A104D Quad T1/E1 PCI Card with Onboard Hardware DTMF Decoding and Echo Cancellation - Carrier Grade Hardware for Asterisk
The Sangoma A104D 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 Sangoma A104D provides full speed 132 Mbps PCI bus transfer with FPGA and optional 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 A104D is field upgradeable to take advantage of the hardware and software improvements as they become available.

The new Sangoma A104D has a host of impressive features including:

* 4 port T1/E1 PCI card compliant for 3.3V/5V compliant
* telco grade features for the softPBX/switch marketplace
* T1/E1 and fractional T1/E1, single channel HDLC per line.
* full hardware support for 1024 taps (128ms) of echo tail across all DS0's.
* on board hardware based DTMF decoding
* on board hardware based noise reduction and voice enhancement technology
* full FCC Part 15, FCC Part 68, CE, with other certifications to follow.

The Sangoma A104D 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 A104D also features on-board TDMF decoding and tone recognition.
