(Does not Include Modules)

Sangoma built its business by designing hardware that simply works, the first time. We have taken the time to ensure our BRI solution delivers.

The Sangoma A500 S/T BRI Interface Card delivers superior audio quality and scalability. Expand from two to twenty-four ports of BRI with optional Octasic® Telco-grade, hardware echo cancellation.

A single PCI or PCI Express slot hosts the connection for up to 24 ports and ensures common synchronous clocking for all channels with no signaling issues. The card is 100% software configurable.

Finally, a BRI card that upholds Sangoma's high standards of quality in engineering and untiring product support.

Architecture

The A500 consists of a Remora® BRI daughterboard mounted on the AFT PCI card. The Remora® BRI card has three sockets, each of which can accept an S/T BRI module.

One S/T BRI module has two S/T four wire interfaces, which support TE or NT modes of operation. Changing modes requires no jumpers simply invert the module.

Up to three additional Remora® daughterboards can be mounted in empty slot positions beside the A500 assembly. These are connected to the A500 by a special backplane bus connector.
