Installing a Telephone Modem Battery

Solution

This battery is only intended to back up phone service in the event of a power outage. It is not intended to back up Internet service. If you have a home alarm system or home health monitoring system that relies on the telephone line to operate, you will lose access to those services during a power outage unless you have backup batteries in each piece of Cox telephone equipment.
