[TriLUG] OT: Home Security without the phone line?

[Bill Weinel via TriLUG]

All local AT&T switching offices have large battery banks which can run 
their systems for days with no utility power. They also have generators 
in order to charge the batteries... which is why the POTS phone system 
stays up even during widespread power outages. Most ISPs don't invest in 
the same amount of power infrastructure to keep their services up during 
an extended power outage. If you're using telephone service for alarm or 
security purposes, the best bet is to use POTS telephone service. 
Otherwise, for VOIP phone service, the next best thing is to use a 
cellular phone service since most cell sites are generator powered 
during a widespread power outage.


cheers,

Over the years many people report that their phone service stays up during ice/snow storms and hurricanes when nearly every other utility fails.
