Sangoma A56 Data Card

The Sangoma A56 Data Card is the alternative to an external router when using a 56kbps Digital Data System Line connection. This card replaces the Sangoma S5145.

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 card that also works back-to-back over multiple kilometres 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.
