The A108 is the octalport
version of Sangoma's family of Advanced, Flexible
Telecommunications (AFT) hardware designed for optimum support of voice
and data over T1, E1 and J1.
Obtainable in both PCI (A108) and PCI Express (A108E) form factors, the
A108 provides up to 16.4Mbps of full duplex data throughput or 240
voice calls over eight T1 and or E1 lines to support high performance
PCI-based routing and telephony systems. Advanced clocking features
allow E1 and T1 lines to be mixed with full synchronization. As part of
Sangoma's AFT range of products, the A108 makes use of the same high
performance PCI interface that has been deployed in large quantities
all over the world.
The available A108D and A108DE cards include Octasic®'s DSP hardware
and certified algorithms providing carrier-grade echo cancellation and
Voice Quality Enhancement (VQE) functions. Like all the Sangoma AFT
family, the A108 is field upgradeable to take advantage of hardware and
software improvements as they become available.

Eight T1/E1 ports with a single PCI interface for high
performance voice and data applications.
TDM clocking mode: Network timing can be passed from a
network -connected DS0 to any or all of the other ports. Both T1 and E1
are supported simultaneously, making it possible to mix T1 channel
banks and E1 networks with full channel synchronization.
Line decoding: HDB3, AMI, B8ZS. Framing: CRC4, non-CRC4,
Support for the Asterisk™, OPAL™ Yate, FreeSWITCH™ PBX/IVR
projects, as well as other Open Source and proprietary
PBX/Switch/IVR/VoIP gateway applications.
All Sangoma's AFT products, including the A108 card use the
same base PCI interface card, and the same professionally engineered
firmware on the same family of Field Programmable Gate Arrays.
A108, A108D PCI: Fully PCI 2.2 compliant, compatible with
all commercially available motherboards, proper interrupt sharing
without manual tuning.
A108E, A108DE PCI Express: 1 Lane PCI Express bus.
Dimensions: 2U Form factor: 120mm x 55 mm for use in
Short 2U compatible mounting clips included for
installation in 2U rackmount servers.
High quality, tested RJ45 cables included. Power: 800mA
peak, operational 300mA max at +3.3v or 5v.Temperature range: 0-50C.
Autosense compatibility with 5v and 3.3v PCI busses.
Intelligent hardware: Downloadable Field Programmable Gate
Array programming with multiple operating modes. Field upgradeable so
that new features related to voice and/or data can be added when they
32 bit bus master DMA data exchanges across PCI interface
at 132Mbytes/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.
EDAC™ (patent pending) technology will be integrated to
drastically reduce the cost of echo cancellation.
Field upgradeable hardware allows for new TDM-related
functions to be added as they become available.
Raw bitstream interfaces can be used to support arbitrary
non-standard line protocols such as non-byte aligned monosynch or
WAN data connection is supported by Sangoma's standard
WANPIPE® routing stack, and is completely independent of TDM voice
