Overview

Sangoma A101D ATF Card supporting single T1/E1/J1 or fractional T1/E1/J1 data streams with 1024 tap (128ms) hardware based echo canceller across 30 channels.  The A101D Interface Card with Echo Cancellation is is part of Sangoma’s family of Advanced Flexible Telecommunications hardware product line. It uses the same high-performance PCI or PCI Express interface that provides superior performance in critical systems. The Sangoma A101D supports up to 2.048 Mbps of full duplex data throughput or up to 30 voice calls over a single T1, E1, or J1 line.

Sangoma A101D ATF Card Features:

• One T1/E1/J1 port with optimum PCI Express or PCI interface for high performance voice and data applications.
• Line decoding: HDB3, AMI, B8ZS.
• Framing: CRC-4, Non CRC4, SF, D4. Also compatible with Japan’s J1.
• Support for AsteriskTM, YateTM, and FreeSwitchTM PBX/IVR Projects, open source and proprietary PBX/Switch/IVR/VoIP gateway applications.
• All of Sangoma’s AFT products use the same base PCI interface card and the same professionally engineered firmware on the same family of Field Upgradeable Gate Arrays.
• Compatible with all commercially available motherboards - proper PCI-standard interrupt sharing without manual tuning.
• A101-X and A101D-X PCI Express: 1 Lane PCI Express bus.
• 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.
• Power: 800 mA peak, operational 300 mA max at +3.3 V or 5 V.
• Temperature range: 0–50 °C.
• Autosense compatibility with 5 V and 3.3 V PCI busses.
• Downloadable FPGA programming with multiple operating modes.
• 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.
• Use 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.
• Optional DSP daughterboard on the A101DE
• G.168–2002 echo cancellation in hardware.
• 1014 taps/128ms tail per channel on all 256 channels.
• DTMF decoding and tone recognition.
• Voice quality enhancement: Octasic music protection, acoustic echo control, and adaptive noise reduction.
