Power dependent landline phone and internet services

Most people use landline phone handsets, modems and other devices that need power to operate and therefore will not work in a power outage. The NBN also requires power to supply both landline phone and internet services.

During a power outage, in the majority of circumstances an NBN landline phone and internet service will not operate. This is not a new situation for many people. However, this may be a significant change for some people and additional precautions may need to be taken prior to migrating services to the NBN, such as having access to a charged mobile phone.  

You may need all, or a combination of the following for a home (or business) phone that uses the NBN to operate in a power outage:

  • A home (or business) phone which does not plug into a power socket.
  • If relevant, a service provider that offers phone services over the voice
    (UNI-V) port. Not all NBN connections have a UNI-V port.
  • A service provider that offers a battery backup service that provides backup power to the nbn equipment in your premises. Battery backup is not available on all nbn connections and not all providers offer battery backup.
  • An alternative power source (such as batteries or an uninterruptible power supply (UPS)) for any connected customer equipment such as your phone handset, modem, medical/security or fire alarm monitoring equipment.

Key questions to ask your provider

If phone services are important to you during a power outage:

  • Ask your phone/internet service provider if your phone service will operate during a power outage.
  • Ask your alarm provider if your alarm service will operate during a power outage.
  • Check with your internet service provider that your existing equipment such as gateway devices (modems/routers) are compatible with the NBN.
  • Ask your service provider what options you have, or products and services your service provider offers, to ensure your services will operate in a power outage.

Be prepared, be informed and stay connected.
