The A104 is Sangoma’s next generation hardware designed for optimum support of data and voice over
T1 and E1. Sangoma A104 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
