The Sangoma A500RA daughterboard is designed to expand an A500 series BRI card. Each Remora daughterboard can host up to three BRI modules. At capacity, each A500 series PCI base card can dock four daughterboards.
A modular design enables the Sangoma A500 series PCI cards to offer up to 24 BRI ports. Scale the card to your network's requirements rather than having to scale your devices to match your card.
