• Loop current range: 13-110mA
• Voltage detection threshold is software-selectable
• Ring Generation and Ringing Trip
• Loop Closure Detection
• Loop Disconnect
• Loop Reversal
• Loop Voltage and Current Monitoring
• On-hook and Off-hook Transmission
• Hook-flash Detection
• DTMF Signalling
• Programmable Audio Gain
• On-board Power Generation
• Constant Loop Current: 20mA
