Sangoma A104D T1/E1 Card
Ports: 4 T1/E1
Interface: PCI
Warranty: Five years parts and labor
Includes Hardware Echo Cancellation
Product Description
The 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.
A104d QUAD T1/E1 AFT card based on AFT PCI Technology with on board DSP Octasic
Chipsets for on board voice enhancement 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 A104d 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 A104d is field upgradeable to take
advantage of the hardware and software improvements as they become available.
Voice modes:
- The A104d and drivers fully support TDM voice gateways for the Asterisk, Yate,
OPALT PBX/IVR projects, as well as other Open Source and proprietary PBX/Switch/IVR/VoIP
gateway applications.
- Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI.
-
Optimized per channel DMA streams and hardware-level HDLC handling unload the
host CPU.
- EDAC (patent pending) technology is integrated to drastically reduce the load
due to software echo cancellation, which is the largest component of CPU load in
a typical soft PBX system.
- Field upgradeable hardware allows for new TDM-related functions to be added as
they become available.
Mixed Voice/Data mode:
- Robust combination of router/PBX functions in one server.
-
WAN data connection is supported by Sangoma’s standard WANPIPE routing stack,
completely independently of TDM voice application for total system reliability.
-
WANPIPE supports certified, field tested and reliable Frame Relay, PPP, HDLC
and X.25.
Technical Specifications
- Quad port T1/E1/J1 card.
- Dimensions: 2U Form factor: 120mm x 55 mm for use in restricted chassis.
-
32 bit bus master DMA data exchanges across PCI interface at 132Mbytes/sec for
minimum host processor intervention.

integrity on high volume systems.
- Intelligent hardware: Downloadable Field Programmable Gate Array programming
with multiple operating modes. Allows new features related to voice and/or data
to be added when they become available.
