The Sangoma A104
Card:Four ports of optimized voice and data over T1, E1, and JI
with Telco-grade hardware echo cancellation.
Part of Sangoma's award-winning Advanced Flexible Telecommunications
product line, the A104 uses the same high-performance PCI or PCI
Express interface that is providing superior performance in critical
systems all over the world. The A104 supports up to 120 voice calls or
8.192 Mbps of full-duplex data throughput over four T1, E1, or J1 lines.
Take advantage of hardware and software improvements, as soon as they
become available. Like all cards in Sangoma's AFT family, the A104 is
field upgradable with crash-proof firmware. Choose the Sangoma A104D
and A104DE cards with Octasic®'s DSP hardware and certified algorithms
to achieve carrier-grade echo cancellation and Voice Quality

Four T1/E1 ports with a single PCI or PCI-Express interface
optimized for high performance voice and data applications.
Mix T1 channel banks and E1 networks with full channel
synchronization. TDM clocking mode lets network timing to be passed
from a network-connected DS0 to any or all of the other ports, so both
T1 and E1 are supported simultaneously.
Support for Asterisk®, Yate™, CallWeaver™ and FreeSWITCH™
PBX/IVR Projects, as well as other open source and proprietary PBX,
Switch, IVR, or VoIP gateway applications.
All of Sangoma’s AFT products use the same base PCI
interface card. Fully compatible with all commercially available
motherboards - proper PCI-standard interrupt sharing without manual
Dimensions: 2U Form factor: 120 mm x 55 mm for use in
Includes high-quality, tested RJ45 cables and short 2U
mounting clips for installation in 2U rack-mount servers.
Intelligent hardware: Downloadable FPGA programming with
multiple operating modes. Add new features related to voice and/or data
when they become available.
Autosense compatibility with 5V and 3.3V PCI busses.
Line decoding: HDB3, AMI, B8ZS.
Framing: CRC-4, Non CRC4, ESF, SF, D4T1/E1. Also compatible
with Japan’s J1.
A104E and A104DE PCI Express: 1 Lane PCI Express bus.
Power: 800 mA peak, operational 300 mA max at +3.3 V or 5
Temperature range: 0 - 50 °C.
32-bit bus master DMA data exchanges across PCI interface
at 132 Mbytes/sec for minimum host processor intervention.
Ring buffer DMA handling for minimum host intervention and
guaranteed data integrity on high volume systems.
Supports Robbed Bit Channel Associated Signaling (CAS) and
T1/E1 and fractional T1/E1, multiple channel HDLC per line
for mixed data/TDM voice applications.
Optimized per channel DMA streams and hardware-level HDLC
handling unload the host CPU.
Uses raw bitstream interfaces to support arbitrary
non-standard line protocols, such as non-byte aligned monosynch or
WANPIPE® routing stack is completely independent of TDM
voice application for total system reliability.
WANPIPE® supports certified, field-tested, and reliable
Frame Relay, PPP, HDLC, and X.25.
