The Sangoma A108 Card: eight ports of optimized voice and data over T1, E1, and J1 with Telco-grade hardware echo cancellation.
The A108DE includes Hardware Echo Cancellation with 1024 taps (128ms) across all channels
Part of Sangoma’s award-winning Advanced Flexible Telecommunications product line, the A108DE (formerly known as A108D-X) uses the same high-performance PCI Express interface that providing superior performance in critical systems all over the world.
The A108DE supports up to 240 voice calls or 16.384 Mbps of full-duplex data throughput over eight 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 A108DE is field upgradable with crash-proof firmware.
Choose the Sangoma A108DE card with Octasic®’s DSP hardware and certified algorithms to achieve carrier-grade echo cancellation and Voice Quality Enhancement functions on your open source or even proprietary telephone system.
Eight T1/E1 ports with a single 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 Express interface card. Fully compatible with all commercially available motherboards—proper PCI-standard interrupt sharing without manual tuning.
Dimensions: 2U Form factor: 120 mm x 55 mm for use in restricted chassis.
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.
Line decoding: HDB3, AMI, B8ZS.
Framing: CRC-4, Non CRC4, ESF, SF, D4T1/E1. Also compatible with Japan’s J1.
1 Lane PCI Express bus.
Power: 800 mA peak, operational 300 mA max at +3.3 V or 5 V.
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 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.
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 bisynch.
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.
