Sangoma A101 Single Span T1/E1/J1 PCI card

The Sangoma A101 is 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.

The Sangoma A101 supports up to 30 voice calls over a single T1, E1, or J1 line.

With Sangoma cards, you can always take advantage of hardware and software improvements, as soon as they become available. The Sangoma A101, like all cards in Sangoma's AFT family, is field upgradeable with crash-proof firmware.

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.
