Sangoma A101E Product Description

The Sangoma A101E is the industry leading single port T1/E1 telephony card with a PCI Express motherboard interface. The A101E is designed to work with voice over IP communications IP PBX platforms such as trixbox, asterisk, CentPBX as well as other open source and proprietary PBX/Switch/IVR/VoIP gateway applications.

The A101E supports up to 30 channels/voice calls over a single T1, E1, or J1 line. It is a part of Sangoma's family of Advanced Flexible Telecommunications hardware product line - it uses the same high-performance PCI Express interface that is providing superior performance in critical systems all over the world.

Sangoma A101E Operational Modes

• Data only:
  • T1/E1 and fractional T1/E1, single channel HDLC per line.
• Voice mode:
  • Supports Robbed Bit Channel Associated Signaling (CAS) and ISDN PRI.
  • Block mode raw bit-stream interface for integration with the Asterisk Open Source PBX/IVR platform.
  • Channelized mode supporting individual DMA into voice timeslots plus onboard HDLC support of PRI channel for soft PBX implementations that can use these features.
• Mixed Voice/Data Mode:
  • Combination of router/PBX functions in one server - Asterisk as an option.
  • Both 8 bit (64kbps per channel) and 7 bit (56kbps per channel) board-level HDLC support.
  • WAN data connection is supported by Sangoma’s standard WANPIPE® routing stack providing certified Frame Relay, PPP, HDLC and

A101E Technical Specifications

- 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.
