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.
Sangoma A101 Digital Telephony Card Overview
The Sangoma 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 Sangoma A101 supports up to 2.048 Mbps of full duplex data throughput 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 Sangoma A101, like all cards in Sangoma's AFT family, is field upgradeable with crash-proof firmware.
Sangoma A101 Features and Functions
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.
