With Fibre to the Premises (FTTP) nbn supplies and installs a connection box within your home or business which requires power to operate. Optional battery backup is available from nbn, but you need to speak to your service provider to order a telephone service that uses the battery backup. This service needs to be used with a telephone that does not require mains power to be able to operate during a blackout. Unless you have battery backup and a corded phone correctly connected, your phone won’t operate in a blackout.
Battery Backup is required for Priority Assistance customers. If you have a life-threatening illness, please discuss this with your service provider.
During a power blackout, battery backup may last for approximately five hours (this includes the battery emergency reserve which offers approximately three to three and a half hours initially, and around another one and a half hours once the ‘Battery Emergency’ button is pressed). All mains powered equipment connected to the nbn™ network will need its own separate battery backup to work in a power outage. Further information is available in the FTTP user guide.
Devices connected to the nbn™ network, including your landline phone and internet, won’t work in a power blackout. You should consider keeping a charged mobile phone in case there is a power outage.
Landline phones and internet services won’t operate during a power outage, so you should consider keeping a charged mobile phone.
The equipment to operate Fixed Wireless and Satellite phone and/or internet services needs electricity and won’t work in a power outage. When ordering an nbn service in Fixed Wireless or Satellite areas, have a discussion with your service provider about your existing landline. If you have an existing copper phone line it is important to consider keeping it in service for emergency communications, especially if you don’t have good mobile phone coverage at your home or business.
If you use any of the following equipment, you should talk to your equipment provider about whether your device will work when connected to the nbn™ network and what alternative solutions are available if it doesn't. Certain devices, including those of that are safety-critical such as medical alarms, may not be compatible with the nbn™ network at all times (including, but not limited to, during a power blackout).
