Sorry for the very noobie topic.

I read here and there about fibre affecting alarm monitoring and St John alarms and the like.
So I got to wondering, and I cant recall seeing it mentioned specifically anywhere, does that mean when you get fibre your ordinary telephone handsets wont work anymore?

Are there handsets that will work on both platforms?

Its not something I have to worry about for at least a year according to the Chorus map.

However, forewarned is forearmed and all that.
