Fiber-To-The-Home Telephone Services

Fiber-to-the-Home Telephone Service Works Differently than Copper Connections during Power Outages


Unlike traditional copper wire telephone service, your fiber-to-the-home (FTTH) connection requires a battery backup unit so it can continue to work during a power outage. This is an advantage of fiber vs cable internet. A battery backup unit was set up at your home or business when Kingdom installed your FTTH connection. The unit will provide approximately eight hours of telephone service during a commercial power outage. If the outage lasts longer than eight hours, your landline telephone will not work until power is restored.


What You Need to Know


  • The battery back-up unit should be plugged into a 110V AC commercial power outlet that does not turn off with a switch. In other words, the outlet must always be live. The AC light on the front of the backup unit will be green when the unit is connected and charging.
  • Telephones that require commercial power will not function during a power outage. This includes cordless phones. To maintain telephone service, make sure you have a basic phone with a telephone cord.
  • When an outage occurs, the FTTH electronics enter an economy mode so power may be provided for the longest period of time. For most subscribers, this means that Internet service will be shut down to conserve the batteries for telephone emergency use.
  • If you have a generator at your home or business, you will be able to maintain Internet service during a power outage. Just make sure your battery backup unit is plugged into an outlet that is served by the generator.
