Switching on tone dialing
Starting with this command, each dial up is performed with the tone dialing method,
until an ATP or ATDP command switches it back to pulse dialing.
Phone Line Voltage Measurement (Tip Ring Voltage)
Use the command AT-TRV to measure the phone line voltage (Tip Ring Voltage). The
result is yielded in volt. For an existing connection the voltage range will be 5V – 12V.
Otherwise the voltage is higher than 20V. If the voltages are lower than 2V, no phone
line is connected.
