The A102 is the dual port version of Sangomas family of Advanced, Flexible Telecommunications (AFT) hardware designed for optimum support of voice and data over T1, E1 and J1.
Obtainable in both PCI (A102) and PCI Express (A102-X) form factors, The A102 provides up to 8.2Mbps of full duplex data throughput or 60 voice calls over two 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 Sangomas AFT range of products, the A102 makes use of the same high performance PCI interface that has been deployed in large quantities all over the world. The available A102d and A102d-X 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 A102 is field upgradeable to take advantage of hardware and software improvements as they become available.

More About Sangoma A102 Dual-T1/E1/J1 PCI Bus
Two 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, ESF, D4T1/E1.
Support for the Asterisk, OPAL Yate, FreeSwitch PBX/IVR
projects, as well as other Open Source and proprietary
PBX/Switch/IVR/VoIP gateway applications.

upgradeable so that new features related to voice and/or data can be
added when they become available.
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 ISDN PRI.
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
bisynch.
WAN data connection is supported by Sangomas standard
WANPIPE routing stack, and 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.
