4 port modular analog PCI 3.3/5.0V card with 4 Trunk interfaces. The 1A4A02F from the A4 Series is a PCI card for 3.3/5.0V with 0-FXS/4-FXO and 4 ports. This PCI card includes four FXO modules. The modular design of the Digium A4-series analog cards means the modules are interchangeable. In other words, remove one of the FXO modules and replace it with an available FXS module.
