Here are some measurements for the ONT610(X) with regards to power consumption.
Power draw from 48V PSU when operating on mains power:
Battery disconnected: 12W
Battery actively charging: 18W
Operating on battery power:
Data, video and POTS active: 8.2W
Data and POTS active: 6.1W
POTS only active: 5.8W
The number of POTS lines and their on/off-hook status will have minimal effect on the power. However, a ringing line is likely to increase the power consumption considerably.
