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
