Caratteristiche tecniche:

One T1/E1 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, ESF, SF, D4. Also compatible with Japan’s J1.
Support for AsteriskTM, YateTM, and FreeSwitchTM PBX/IVR Projects, as well as other 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.
Fully 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.
Intelligent hardware: Downloadable FPGA programming with multiple operating modes. Add new features related to voice and/or data when they become available.
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 A101D
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.
