Backup Power for Telephone Service during Power Outages :

For many years, your home telephone would allow you to stay connected to emergency voice services during a power outage. However, your residential voice telephone service is provided by fiber optics via the Optical Network Terminal (ONT) and requires backup battery power to continue functioning during a power outage.

To avoid a disruption during a power outage, and to maintain the ability to connect to 911 emergency services, SMTA provides you with a standard 8 hour battery with backup power for your residential voice telephone service at the time of the initial installation at no additional cost. The backup battery provided by SMTA for powering the fiber optic ONT allows you to continue to use your home voice services during a power outage.

Proper Usage and Storage Conditions :

The battery is intended to enable users to make short, emergency or other urgent telephone calls. During an extended power outage, use your telephone sparingly to preserve your battery life. The actual length of time that your telephone service will be available during a power outage depends on many variables, including, but not limited to, the following:

  • (i) the amount of phone usage when utilizing power from the backup battery
  • (ii) whether a backup battery is properly installed and charges, such as whether it has had an opportunity to fully recharge after a power outage
  • (iii) the condition and age of the backup battery
  • (iv) the amount of prior usage of the battery. Batteries lose capacity with age. Batteries can also lose power if they are frequently charged and discharged. Failure to adhere to proper storage and usage conditions will reduce the talk time available when you are in an outage and the lifespan of your battery.

What Your Battery Can - and Can't - Do for You :

SMTA's backup batteries for telephone ONT's are expected to provide at least 8 hours of standby power. The backup battery should give you at least 2 hours of talk time. If you feel that is not enough time, you may extend your standby power by purchasing additional spare 8-hour batteries from SMTA.

Our backup battery does not provide power to any services other than voice. Internet, CATV, home security systems, cordless phones, medical monitoring devices, and other equipment will not run on a residential voice telephone backup battery.

Replacement and Spare Battery Purchase Options :

The battery provided by our company may need to be replaced every eight to ten years or when the battery no longer functions. SMTA will provide and install a replacement backup battery at no cost, when it becomes known that the battery needs to be replaced. Should you desire a spare backup battery, it can be purchased from SMTA at our main office. Please call for pricing. You can also purchase additional spare backup batteries to keep on hand in your home.
