  • The ONT is the box where Frontier's fiber network comes into your home. It is usually located on the side of your house or in your garage.
  • New Frontier Vantage customers or new customers with DPU / DPE over Fiber in Indiana, Oregon and Washington (if this is your first account with Frontier) who have an ONT will receive free Sealed Lead Acid (SLA) BBU for their ONT with their voice order.
  • New California residents with FiOS Digital Voice or Freedom/Regional Essentials over Fiber (if this is your first account with Frontier) will receive free Power Reserve BBU for their ONT with their voice order.

Vantage Voice over Fiber* Customers:

Frontier Vantage Voice will work for a minimum of 8 hours if you have:

  1. A Sealed Lead Acid battery in the ONT, and
  2. A Belkin BBU in the Frontier Residential Gateway (RG).

The battery in the ONT provides an electrical signal to the RG. The Belkin BBU in the RG keeps Vantage Voice operational in the event of a power outage.

*Vantage Voice over Fiber is currently offered in select areas of:

  • Chester, New York
  • Durham, North Carolina
  • Minnesota
  • North Myrtle Beach, South Carolina

Your Frontier VoIP phone service, including 911 service, will not function without electrical or battery backup power. In the event of a power outage, you may not be able to make calls and you should ensure that you have a functioning battery backup for the Residential Gateway (RG) or the Optical Network Terminal (ONT), or an alternate means of calling 911. Battery backup is optional and can be purchased for $39.99 per battery.
