The A101 is Sangoma’s next generation hardware designed for optimum support of data and voice over T1 and E1. Sangoma A101 gives you unparalleled flexibility at a great price.

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 YATE 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 - Yate 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
