SKU: A500BRME Categories: , ,


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 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.


The A500 consists of a Remora© BRI daughterboard mounted on the AFT PCI Express 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 Sangoma A500 by a special backplane bus connector.

Technical Specifications

  • From 2 to 24 ports are supported. Mix TE and NT modes, as required. Changing modes requires no jumpers – simply invert the colour-coded module.
