The A108 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 is providing superior performance in critical systems all over the world.

The A108 supports up to 16.4 Mbps of full duplex data throughput or up to 240 voice calls using up to eight T1, E1, or J1 lines.

With Sangoma cards, you can take advantage of hardware and software improvements, as soon as they become available. The A108, like all cards in Sangoma's AFT family, is field upgradable with crash-proof firmware.

Choose the Sangoma A108D and A108DE, equiped with world class DSP hardware to achieve carrier-grade Echo Cancellation and Voice Quality Enhancement functions for your telephone systems.

Technical Specifications

• Eight T1/E1 ports with optimum PCI or PCI–Express interface 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 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 port-splitter cables and short 2U mounting clips for installation in 2U rack-mount servers
• 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
• Line decoding: HDB3, AMI, B8ZS
• Framing: CRC-4, Non CRC4, ESF, SF, D4. Also compatible with Japan's J1
• A108E and A108DE PCI Express: 1 Lane PCI Express bus
• Maximum operational power for PCI: 7.5 W (1.5 A 5 V) For PCI Express: 5.5 W (1.67 A 3.3 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
• 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

Optional DSP Hardware Echo Canceller Daughterboard

• G.168–2002 echo cancellation in hardware
• 1024 taps/128 ms tail per channel on all channel densities
• DTMF decoding and tone recognition
• Voice quality enhancement: music protection, acoustic echo control, and adaptive noise reduction
• Does not increase the physical size of the card, and no additional slot is required
