System Requirements
The RG Battery Backup is designed for use with the AT&T U-verseSMResidential Gateway and your AT&T U-verseSMVoice service.
NOTE: Your AT&T U-verseSMVoice service, including 911 dialing, will not function without electrical or battery-backup power. The RG Battery Backup supplies power for your AT&T U-verseSMVoice service; it does not supply power for cordless phones (and it does not supply power for your network interface device or optical network terminal, typically located on the outside of your home, which may also require battery-backup power for your AT&T U-verseSMVoice service to function).
Therefore, in the event of a power outage, you should ensure you have one corded single-line, touchtone phone connected directly to the AT&T U-verseSMResidential Gateway or your in-home wiring and the AT&T U-verseSMResidential Gateway connected to the RG Battery Backup. (Rotary/pulse phones do not work with AT&T U-verseSMVoice service.) If you connect more than one corded phone, it will use more power; if you connect a cordless phone, it will not function without a separate battery backup, and not all cordless phones are so equipped. If you have a monitored home alarm, you should never plug a multi-line phone directly into the Residential Gateway—it could interfere with the alarm signals. You should not connect the RG Battery Backup to
any device other than the AT&T U-verseSMResidential Gateway or use it with any service other than your AT&T U-verseSMVoice service, and you should always have an alternative means of dialing 911, such as via a cellular telephone.
