Sangoma A102D

Sangoma A102D is a digital voice board with PCI interface for two E1 channels with a hardware echo cancellation module and support for CAS and ISDN PRI signaling systems.

The Sangoma A102D PCI card is a digital voice card with a PCI interface for two T1/E1/J1 channels with support for CAS and ISDN PRI signaling systems.

The Sangoma A102D digital cards represent the next generation of Sangoma equipment designed to optimally process data and voice transmitted over T1 and E1 streams.

The Sangoma A102D PCI supports up to 60 telephone connections, providing full-duplex data transmission over two T1, E1 or J1 channels at 4096 kbps.

Sangoma boards allow you to take advantage of new hardware and software features as soon as they become available. The Sangoma A102D board, like all other boards in the Sangoma AFT family, supports in-service firmware updates.
The Sangoma A102D and Sangoma A102DE cards, with Octasic® DSP hardware and certified echo cancellation algorithms, provide telco-grade echo cancellation and improved audio quality in public and private telephone systems.
