The Sangoma A108 and A108d are now in stock and shipping!

The A108 is the octal (8) port version of Sangoma's family of Advanced, Flexible Telecommunications (AFT) hardware, designed for optimum support of voice and data over T1, E1 and J1.

The A108 provides up to 16.4Mbps of full duplex data throughput or 240 voice calls over eight T1 and/or E1 lines to support high performance PCI-based routing and telephony systems, such as Asterisk. Advanced clocking features allow E1 and T1 lines to be mixed with full synchronization.

As part of Sangoma's AFT range of products, the A108 makes use of the same high performance PCI interface that has been deployed in large quantities all over the world.

The available A108d card includes Octastic's DSP hardware and certified algorithms providing carrier-grade echo cancellation and Voice Quality Enhancement (VQE) functions.

Like all the Sangoma AFT family, the A108 is field upgradeable to take advantage of hardware and software improvements as they become available.
