"D" rated cards add hardware echo cancellation. Introducing the industry's first affordable single port T1/E1/J1 card with available Telco-grade hardware echo cancellation. It's designed for optimum voice support for smaller systems.

Choose the Sangoma A101D and A101DE cards with Octasic's DSP hardware and certified algorithms to achieve carrier-grade echo cancellation and Voice Quality Enhancement functions on your open source or even proprietary telephone system.The A101 is Sangoma's next generation hardware designed for optimum support of data and voice over T1 and E1.

Operational Modes

Download A101 Datasheet

• T1/E1 and fractional T1/E1, single channel HDLC per line.
• Can be used as a hub for sub-DS1 remotes. The A101 and A102 can support any configuration of up to 62 DS0s carrying Frame Relay, PPP or HDLC data.
• Raw bitstream interfaces can be used to support arbitrary non standard line protocols such as non-byte aligned monosynch or bisynch.

Voice modes:

• Supports Robbed Bit Channel Associated Signalling (CAS) and ISDN PRI.
• Block mode raw bit-stream interface for integration with the Asterisk Open Source PBX/IVR platform.
• Channelised 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
