Digium Analog Cards

Digium Analog Phone Cards

Digium manufactures analog modules for both Foreign Exchange Station (FXS) extension-side interfaces and Foreign Exchange Office(FXO) trunk-side interfaces. These modules are built both in single-port, for smaller installations, and quad-port, where density is important. The analog cards, with their interchangeable single and quad FXS and FXO modules, can eliminate the requirement for separate channel banks or access gateways.
