Hi. I am making the switch from Telstra adsl to TPG nbn. I have my email saying installation date and that no one needs to be home. Thing is I am working from home on computer with internet required. Will the Telstra adsl still be usable while the installation is taking place?
NBN Installation has different Service Class types. Yours is under Service Class 12 for the NBN FTTN service.
This means that the status of copper is known; jumpering may be required at the node.
Since there is already an existing service, it is likely to work once the tech completes the install. You will receive a notification regarding the outcome of the installation.
