Digital Home Phone battery backup units
Effective February 16, 2016, the CenturyLink Digital Home Phone (DHP) Service for our Residential Customers will include the ability to order a Battery Backup Unit (BBU) if the customer desires, also known as an Uninterruptable Power Supply (UPS).
Please be aware that electrical power is required for DHP Service to work. If there is a power outage, the Service will not process calls, including those to 911.
A BBU will improve the Service's ability to function in such an event. With an active battery, the BBU will provide temporary backup power for the devices in your home that provide basic voice services as well as access to dial Emergency 911.The BBU may not guarantee functionality in the event of a power outage depending on the nature of the outage or if the Service network is out of operation. As a separate service, you may purchase the BBU, including the housing, from CenturyLink or you may purchase the unit from another supplier and install it yourself.
CenturyLink will ship the BBU to your premises within two weeks of ordering the DHP service.
Important information you need to know
In case of an electrical power outage, the CenturyLink BBU should last at least 8 hours in standby mode. While under BBU power, you may not be able to access the Internet and other services, such as security alarms, may not work.
You are responsible for obtaining, monitoring, replacing and properly disposing of all batteries for the BBU. CenturyLink recommends that you check the BBU at least once a year to ensure that the BBU is operating and ready for use should there be a power outage.
IMPORTANT—Failure to maintain your BBU may result in loss of voice service during a power outage, including a loss of access to Emergency 911 and other services.
If you purchased the BBU from CenturyLink, CenturyLink’s warranty covers the replacement of the battery in the event it stops working within the first year. When the BBU is ordered from CenturyLink, it is provided by APC until April 15th, 2016. After that date, it will be provided by Alpha.
More information regarding these units is available here:
Replacement batteries may also be purchased at major battery distributors, including those listed below. Please use this product description when securing the replacement battery: 12 Volt 12 AMP Ah Valve-Regulated (sometimes referred to as "sealed") Lead Acid Battery, Approximately 6" wide by 3 1/2" deep by 4" tall, with quick-disconnect tab posts.
Some batteries may be covered under the BBU equipment supplier's warranty. CenturyLink does not warranty BBU equipment not purchased directly from CenturyLink. If a battery failure occurs, contact the supplier of the BBU to determine whether your battery is under any warranty.
