Battery Backup Information
Please retain for your records
Historically, telephone service has been powered by electrical power within the telephone network.
Your
AT&T Phone service, including 911 dialing, is an enhanced voice communications service that requires
electrical power and will not function during a power outage without battery backup power at your
premises.
Therefore, you must at all times maintain a working backup battery for all of the following components
that apply to your particular AT&T Phone installation. Please refer to the pictures below to determine which type
of unit(s) you have.
You may have a
Wi-Fi® Gateway (WG)
inside your home. It is your responsibility to provide for your own battery
backup. You may choose to purchase battery backup for your WG from third party manufacturers or retailers. For
more information and minimum specifications see below or visit att.com/batterybackup.
