What is Uninterruptible Power Supply (UPS)?
Take me to
An Uninterruptible Power Supply (UPS) is a battery back-up for a compatible Telstra Smart Modem. It can provide power for a Telstra Smart Modem for up to four hours in the event of a mains electricity outage.
This means your Smart Modem will remain online for up to four hours in the event of an electricity outage at your address allowing you to use your home phone line (if it's connected via the nbn® network).
