Backup Battery Notice

TrioTel Communications, Inc. is required to provide you with information regarding the backup battery power supply unit, also described as the Uninterrupted Power Supply (UPS) battery backup, which we installed in your home when connecting your services to our fiber network. Please contact us if you have additional questions on how your TrioTel services operate during a power outage.

Backup Power for Home Phone Service during Power Outages

Over a fiber-optic connection, a backup battery power supply unit (backup battery) is needed to power your digital voice service in the event of a power outage. A backup battery, such as what TrioTel has provided and installed, will allow regular corded landline phones to work during a power outage and maintain the ability to connect to 911 emergency services. When a power outage occurs, you should ensure that you have one corded single-line touchtone phone connected directly to your in-home wiring telephone jack. If you connect a cordless phone, it will not function without a separate battery backup, and not all cordless phones are so equipped.

What Your Battery Can-and Can’t-Do for You

The backup battery will maintain your telephone service and allow you to make emergency calls during a power outage. Without a backup battery or alternate backup source, such as a generator, you will not be able to place any calls, including emergency calls to 911. The backup battery does not provide power to any service other than voice. TrioTel television and internet services will be suspended in order to conserve the battery for phone service and will not function when power is out. The backup battery will not provide power to cordless phones, home security systems, medical monitoring devices, or other electronic equipment.

Purchase and Replacement Options

Backup battery replacements are available directly from TrioTel. If you have any questions on how to request and obtain a replacement unit, as well as, instruction on the installation of the replacement unit, please call 425-2238 or visit our website at

If you decide to purchase a backup battery replacement, please contact TrioTel for information regarding specific models and requirements. Backup battery units can be purchased at many local retailers or on-line.

Expected Backup Power Duration

The backup battery unit we have provided is expected to last up to 8 hours in the event of a power outage. The estimated life expectancy for the battery is 2-4 years. Environmental factors, such as temperature, power outage frequency, usage, and battery age can affect the performance and the life expectancy of the battery. The backup battery unit we have provided performs self-tests and is monitored for life expectancy.

Instructions for Proper Care and Use of Your Battery

If you decide to purchase a backup battery replacement, please follow the instructions included with your battery for proper use, storage, and care. Batteries should be stored in locations under normal room temperatures.

You should periodically remove and test your battery to verify both operation of the backup battery and its condition. The backup unit can be tested by unplugging it from the power outlet. If it is working correctly, the Optical Network Terminal (ONT) will remain powered and regular corded landline phones will still work in the house. Make sure to plug the unit back in at the end of testing.

Backup units will display a battery light when the battery needs to be replaced. Please refer to the backup unit’s instruction manual for details on the warning indicator lights and the battery replacement procedure.

TrioTel does not supply any warranty on the backup battery unit.
