Sangoma A511 is a network interface card with a modular design. This configuration includes an A500 base card, four Remora daughterboards and 11 BRI modules. Each BRI module hosts two BRI ports, equaling 22 ports total for the entire assembly. The Sangoma A511 BRI card connects to the network via the PCI interface.
Expand the A511 card to 24 ports by adding one available BRI module. Or, remove modules and daughterboards as your network requires. The BRI ports on the A511 are also swappable between TE and NT modes. Choose how the card is configured and enjoy Sangoma's high standards for voice and audio quality.
