The 4FXO module supports CooVox-U50/ CooVox-U100/Asterisk Appliance P2 IP Phone System with 4RJ11 ports for PSTN line connection. Each port has one LED(Light-Emitting Diodes). Detects ringing when on-hook. Detects loop current when off-hook. Detects when tip/ring voltage crosses a set voltage when on-hook or off-hook (called DC triggering). Can accommodate private branch exchange (PBX) with –48 V battery voltage. Loop current range: 13-110mA. Voltage detection threshold is software-selectable.
