Power Supply Backup Battery

Battery Replacement in Your UPS

Battery Backup

Fiber to the Home equipment must be powered locally at the residence, however if you lose power at the outlet your ONT (Optical Network Terminal) is plugged into, you will not be able to make or receive telephone calls without the installation of a battery back-up If you do not have a battery back up installed or if it does not work properly you will not be able to make phone calls when there is no electricity at the outlet where the UPS is connected.

Properly maintained and working batteries are designed to provide phone service up to 8 hours in the event of a power outage. The performance of your battery may vary due to age, use, and environmental factors. A UPS with a series of three batteries providing up to 24 hours of backup can be installed if requested.

  • The Battery Backup Unit is meant specifically for your phone service and will not power cordless phones, other devices, including those that assist customers with disabilities or home security systems, or your Internet or TV service.
  • During a power outage, please consider minimizing the call duration of any unnecessary calls to help preserve your battery power. Consolidated will not provide credits and is not liable for interruptions of service due to power outages.
  • There may be other commercially available sources of backup power, such as a generator or an additional uninterruptible power source that may provide backup A/C power for your voice service. Please consult the manufacturers of those types of devices for more information about their functions and capabilities.
