Battery Back-Up Policy



Dais Communications Battery Backup Units

The Dais Communications Digital Home Phone (DOCSIS) (GPON) Service for Residential Customers includes the ability to purchase 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 either phone service to work. If there is an electrical power outage, the phone service will not be available either to transmit or receive calls, including those to 911 for emergencies.

A BBU will improve the Service’s ability to function in the event power is disrupted With an active battery, the BBU will provide temporary backup power for the Dais Communications device 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 and duration 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 Precision Power Solutions or you may purchase the unit from another supplier and install it yourself.

If a Residential Customer has a Cable Modem, the Residential Customer is responsible for securing and purchasing a battery back-up for each Cable Modem. A Cable Modem battery back-up may be purchased from Dais Communications at the standard cost of $85.00 per each battery back-up, with certain exceptions based on product model. If you would like more information about the cost for a battery back-up for your particular Cable Modem, if you would like to purchase a battery back-up for your Cable Modem and/or if you would like to upgrade your Cable Modem, please contact a Dais Communications Customer Care representative at the telephone number printed on your bill.

Important Information You Need to Know

In case of an electrical power outage, the Dais Communications preferred BBU should last at least twenty-four (24) hours in standby mode. While under battery backup power, you may not be able to access the Internet and other services, such as security alarms, may not be available to you.

You are responsible for obtaining, monitoring, replacing, and properly disposing of all batteries for the BBU. Dais Communications recommends that you test the BBU at least twice (2x) each year to ensure that the BBU is operating, fully charged, and ready for use should there be a power outage. Further information on proper usage and storage of the BBU is included in the User’s Manual at the end of this policy.
