Telephony card for Asterisk systems

Sangoma Technologies Corp., which makes connectivity hardware and software products for Asterisk-based PBX solutions, has released the A101D single port E1/T1/PRI card with carrier-grade echo cancellation.

The A101D supports the same digital processing and highly-compatible PCI and PCI Express interfaces as the Toronto company’s other AFT-based family of telephony cards.

It provides the benefits of hardware-based echo cancellation and voice enhancement for smaller, single-port T1/E1 installations. The A101D also supports DTMF encoding/decoding and tone recognition, voice quality enhancement and adaptive noise reduction.

 

“Our A101D is the industry’s first affordable single port T1/E1 card with echo cancellation and was developed in response to the continuing market demand for a small capacity, low-cost E1/T1 card,” says Sangoma Technologies president and CEO David Mandelstam. “As an integral part of Sangoma’s AFT design family, the A101D inherits the compatibility, enhanced performance and reliability of its siblings.”

 

A101D features include:

–Support for PCI Express and PCI bus architectures.

–Support for 1024 taps (128ms) of echo tail handling on every channel (DS0) meaning that troublesome delayed echoes are properly handled.

–Dynamic and selective activation of echo cancellation, making the system ideal for mixed voice/data applications.

–The same PCI interface, architecture and digital path as all of Sangoma’s other AFT based analog and T1/E1 cards.
