The loop start Analog Interface(FXS) provides the following features:

•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 –۴۸ V battery voltage•Loop current range: 13-110mA

•Voltage detection threshold is software-selectable
