Quick Overview

Buy Single Port PRI Digital Card with Echo Cancellation

As claimed by Sangoma it is “industry’s first affordable single span T1/E1/J1 board with available Telco-grade hardware echo cancellation — designed for optimum voice support for smaller systems“ for smaller systems. Sangoma 1 port PRI digital card uses the same high-performance PCI or PCI Express interface that is providing superior performance in critical systems all over the world. It 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.

Optional DSP Hardware Echo Canceller Daughterboard
* G.168–2002 echo cancellation in hardware
* 1024 taps/128 ms tail per channel on all channel densities
* DTMF decoding and tone recognition
* Voice quality enhancement: music protection, acoustic echo control, and adaptive noise reduction
* Does not increase the physical size of the board, and no additional slot is required
