Sangoma A502E 4 Port BRI Card PCI Express

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.

Sangoma A502E 4 Port BRI Card PCI Express

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.
