backup battery Policy


Your Tallahatchie Valley Internet Services provided telephone ONT is powered by plugging it into an electrical wall outlet. In the event of an electrical outage, your ONT will not receive power, just like any other electrically powered device in your home or business. If this were to happen your telephone service, including any medical or security alert services, like E911, will not be available to you.

A backup battery is designed to provide temporary power to the ONT in the event electrical power in your home or business is lost. The length of time that your phone will be available during a power outage depends on many variables, including, but not limited to, the following: (i) whether a backup battery remains properly installed in the phone ONT; (ii) whether a backup battery is properly charged; (ii) the condition and age of a backup battery; and (iii) the amount of phone usage when the phone ONT is utilizing power from a backup battery.
It is your responsibility to provide, maintain, monitor, and/or replace a backup battery.

TAKE NOTE: If you have a medical alert system, or security equipment, you are strongly encouraged to utilize and maintain a battery back-up. Our telephone service is designed to be used on the premises in which service is installed. The equipment that we install in your home or business is the property of Tallahatchie Valley Internet Services. In the event you relocate or disconnect service, you must return the unit/equipment to a Tallahatchie Valley Internet Services office or arrange to have it picked up. If the unit/equipment is not returned, you will be subject to a one-time equipment charge. You assume the risk of loss, theft, or damage to the equipment at all times prior to the removal of the units by Tallahatchie Valley Internet Services or return of the units by you.

You may purchase a backup battery as part of your Telephone Service installation. Please contact Customer Service at 662-563-2075 to learn more about the backup battery policy, including tips on how best to prepare for an electrical outage. Tallahatchie Valley Internet Services does not guarantee the performance of any backup battery.

The Tallahatchie Valley Internet Services installed Optical Network Terminal (ONT) includes a Battery Back Unit (BBU) option, which you may utilize by maintaining an active 12-volt battery in the BBU. With a fully-charged battery, the BBU will provide backup power for your basic voice services, including Emergency 911 dialing, for up to twenty-four (24) hours in the event of a commercial power failure. You are responsible for purchasing and/or replacing the battery in the BBU. We recommend you think about this battery check and replacement just like you would the batteries in your smoke detectors or emergency flashlights.

The BBU is installed at your location in an area where it can be easily monitored. The BBU is connected directly to the ONT to provide backup power if it's needed. In addition, the BBU contains a series of indicator lights that tell you whether your service is being powered by your location's electricity or the battery if one is installed. The BBU also indicates when the 12-volt battery needs to be replaced.

• Low Battery – alarm is silenced after electrical power returns, the battery is fully discharged or removed from the BBU
• Replace Battery – alarm is silenced when the battery is removed
