Sangoma A116 with 16-Span T1/E1/J1 Card is the Ultimate high density solution with sixteen spans of T1, E1 or J1 available with carrier–grade hardware echo cancellation.

Sangoma A116 is part of Sangoma’s family of Advanced Flexible Telecommunications hardware product line – using high performance PCI Express interface, providing superior performance in critical systems all over the world. Sangoma A116 supports up to 32.8 Mbps of full duplex data throughput or 480 voice calls using 16 T1/E1/J1 spans.

With Sangoma cards, you can take advantage of hardware and software improvements, as soon as they become available. Sangoma A116, like all cards in Sangoma’s AFT family, is field-upgradable with our unique unbreakable firmware feature.

Choose the Sangoma A116E and A116DE, equipped with world class DSP hardware to achieve carrier-grade echo cancellation and voice quality enhancement functions for telecommunication systems.


  • 16 T1/E1 spans with PCI Express interface
  • Double the density of any card on the market today
  • Supports up to 480 simultaneous voice calls
  • Supports up to 32.8 Mbps of full duplex data
  • Asterisk® and FreeSWITCH® ready
  • Easier implementation in Asterisk based PBX systems
  • Support for large Value-Added Services
  • Expand large IVR Systems and Call Centers
  • Easier long term maintenance
  • 4-Year warranty


  • Sixteen T1/E1 ports with optimum 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® and FreeSWITCH®
  • Fully compatible with all commercially available motherboards—proper PCI-standard interrupt sharing without manual tuning
  • Dimensions: Full height by half length (107mm x 176mm)
  • Connector: Dense 68 pin SCSI type interface
  • 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, J1 (Japan)

  • Temperature range: 0 – 50 °C
  • 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, SS7
  • 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
  • Impedance: Configurable to 75ohms or 120ohms

Optional DSP Hardware Echo Canceller Daughtercard

  • 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
