Newly redesigned and simplified, the Sangoma B500 S/T BRI interface board delivers superior audio quality and scalability. It expands from two to four ports of BRI, with optional telco-grade hardware echo cancellation.
A single PCI Express slot hosts the connection for up to 4 ports and ensures common synchronous clocking for all channels with no signalling issues.
The B500 consists of a Remora BRI daughterboard mounted on the AFT PCIe board. The Remora BRI card has 2 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.
The B500 has 4 RJ-45 ports, each port can handle one S/T four wire BRI interface with a single standard Cat-5e shielded twisted-pair cable.

Production Quality
Adding an additional Remora card to your existing A500 allows you to add an additional 6 BRI ports, by installing one to three BRI modules. Each A500 can support up to 4 cards, including the base PCI card, for a total of 12 available ports. This card connects to your existing A500 through the use of an external bus connector, which attaches to the rear of the card. It is therefore recommended that you install these cards next to each other in the chassis.
NOTE: When ordering this card to add to your existing A500, please ensure you select the right bus connector for the total number of cards, including the base PCI card, you expect to install in your system. For example, if you plan on having 12 ports in total, you will need the "2 Card Bus Connector", or for 24 ports, you will need the "4 Card Bus Connector".
