Good news. If you have the Hub in Modem mode and use a 3rd party router, The telephone ports will still be active to use for our new fibre line.
That way you can keep your existing home setup as it currently is.
Do you have an exact date the for the switch over yet?
Thanks for letting us know.
You should be absolutely fine there - if you haven't already, you should receive your telephone adapter closer to the time of the switchover.
Let us know if you need to know anything else.
