Get battery backup info for apartments or condos

Do this first

See if your apartment or building is on this list.

If your building isn’t on the list
Find out how to get a 24-hour battery backup system (look at the Digital phone service without AT&T Fiber section for ordering info). This system will keep your phone working in case you lose power and have to call 911. You can also use the battery backup to briefly maintain home alarms and medical alert services.

Using more than 1 piece of AT&T equipment to get voice service in your home, like a Wi-Fi® gateway or optical network terminal (ONT) device? If so, make sure you have a battery backup for each one.

If your building is on the list
In case of a power outage, your phone service including 911 service will cease to function after about 4 to 8 hours. This will occur even if you have longer battery backup power for other equipment used to provide service within your unit.

• We strongly recommend that you have other means of reaching 911, such as from a mobile phone, for use during power outages that exceed 4 to 8 hours.

• Rather than buying 3 units, only buy 1 APC CP12142LI battery backup unit. This will power your gateway so you can use your phone for up to 8 hours or as long as your building’s equipment is operational.

More info

• Buildings on the PDF list use a certain kind of AT&T network equipment to provide our phone service to occupants. This equipment requires substantial power and can operate on batteries for about 4 to 8 hours during power outages.

• Normally we use portable diesel generators to power this equipment beyond 4 to 8 hours. However when this equipment is located indoors, it can’t be connected to a portable generator for safety reasons.

• We contacted your property manager or landlord to install equipment, at our expense, that’ll provide backup power for 24 hours. Your property manager or landlord hasn’t accepted our offer yet or we may be in the process of installing the equipment.
