In rugged, extreme or remote environments, a leased 56k DDS line available from the Telco may be your best choice. Designed for North American DDS services, choose the board that also works back-to-back over multiple kilometers of dry wiring.
The A56 56kbps DDS hardware is based on the same advanced engineering design as the award-winning AFT Product Line. Trust the Sangoma® name to deliver optimum data support on standard telecommunications networks.
