Li-36 Battery Upgrade

Product Overview

Approved for Consolidated Communications Service

Your Consolidated Communications telephone service is provided over our Fiber to the Premises (FTTP) network. The FTTP network uses hair-thin strands of glass fiber and laser-generated pulses of light called fiber optics to transmit your voice communications. This very reliable network differs from Consolidated’s more traditional copper wire based network in one key way: If electrical power is lost at your home, your landline voice telephone service will not work and you will not be able to dial 911 in an emergency unless you have a working backup power source.

To ensure you always have a working home phone, it is suggested to purchase a UPS (Uninterruptable Power Supply). UPS is used to restore power to the Optical Network Terminal (ONT) when commercial power goes down from the power company. The ONT will be powered while commercial power is down for 8 hours or 24 hours based on the PSI configuration. The ONT provides the Ethernet connection and voice connection to the home from Consolidated Communications. Other Ethernet devices would need their own UPS to keep power in the home network if other devices are used.

A single battery module will keep your ONT in service for up to 8 hours when commercial power goes down. You can add up to 3 battery modules to the power supply for 24 hours of ONT uptime. Installation is simple by sliding in battery modules on to your current power supply provided by Consolidated Communications. Li-36 UPS is designed as the world’s only scalable capacity UPS for fiber/VoIP services. Li36 UPS physically is a very small foot print (6.1in x 3.5in x 2.25) with a single battery module weighing total 1.76lbs.
