If your premises is yet to be connected to the nbn network
You will need to identify the emergency telecommunication systems within your building including identifying the correct service phone number(s).
Discuss your options as soon as possible for switching your emergency telecommunication systems to the nbn™ or alternative network with your services provider(s).
Once you have decided on the most reasonably practicable solution, work with your service provider(s) to manage the migration process.
Upon completion of the migration process, check that all emergency telecommunication systems are operating properly and inform nbn that your services have been successfully migrated.
Continue to monitor your emergency telecommunication systems to ensure they are operating properly.
