Sangoma A102U

The A102U is Sangoma’s next generation hardware designed for optimum support of data and voice over T1 and E1.

Voice Modes

• 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.
