Hi. 

I've had a good look around, and can't see any obvious signs this is possible but thought I'd check. 

I have a customer going to leave their VDSL in as a second backup option in case their new UFB connection ever goes down and since the Zyxel supports ADSL/VDSL/UFB I thought I'd check and see if it were possible for the VDSL to bethe failover in the event of a UFB Failure?

I can see 3G Backup options.

Cheers
