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 A101 is part of Sangoma's family of Advanced Flexible
Telecommunications hardware product line - it uses the same
high-performance PCI or PCI Express interface that is providing
superior performance in critical systems all over the world. The A101
supports up to 2.048 Mbps of full duplex data through-put or 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 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.
