Anybody know how long the battery in a VDSL cabinet is meant to last? A couple of weeks ago we had an all-day power outage - my UPS lasted several hours but the VDSL went dead after an hour. Then the day after the Auckland storm we had a half hour outage but the VDSL only lasted about 5-10 minutes. I think I'm on TBY/F.
Thanks,
Matt.
