1.Where would I find my battery backup unit? Where's it located?
When installed by an ETC technician, it varies. Most are placed out of the way in a basement, laundry room, closet, utility room, etc.
2.What is the purpose of the battery backup?
Home phone service is powered on an ETC network that requires electricity. Because electricity can be subject to power outages, ETC placed battery backup in your home to avoid disruption of home voice service during a power outage. This maintains the ability to connect to 911 emergency services or any other call from your home phone. The battery backup was placed when service was set up.
The battery backup does not provide power to any services other than voice. Home security systems, medical monitoring devices, routers and other equipment will not run on a home phone battery backup.
The landline phone must be directly plugged into the wall jack for it to work during a power outage. This will not work on cordless phones because the phone base needs power.
3.When is a battery backup installed?
A battery backup unit is installed if you live in a fiber area and sign up for landline phone. In CMTS service areas battery backup is built into the modem, however, it will only keep your landline phone working in case of a power outage. Battery power will last up to 8 hours.
4.How can I check if my battery is good or bad?
You can simply call in to have this checked remotely to determine if the battery is good and functioning properly. If you happen to locate the battery on your own, LED light indicators will tell if the battery is good or bad. A green light is good and red light is bad. The battery backup does have an audible alarm, but most of the time this is disabled.
5.If the battery is bad, what happens?
ETC will schedule a technician to go to your home and replace the battery free of charge.
6.Does ETC charge for a technician to replace or fix the battery backup unit?
No. There is no charge.
7.What is the difference between the Fiber and CMTS battery backup?
ETC currently uses and maintains two different network types that will require a battery backup for phone service to operate during a power outage. One is our fiber optic network and the other is called CMTS (or a standard coaxial cable network). The fiber battery backup is a different device than the CMTS battery backup. The fiber battery backup is a separate unit directly connected to the outside box placed on the home (called an ONT), while the CMTS battery backup is built into the modem placed in the home. An example of the fiber battery backup can be found at: : https://www.cyberpowersystems.com/product/fttx/cs24u12v/
8.Is it possible to have battery backup and not have landline service?
Yes. If you are a CMTS customer this is built into the modem that provides service to the home regardless if you have a landline. If you are a fiber customer without a landline phone, technicians may or may not install the battery backup at the time of install. If you had landline service and disconnected it, or the home previously had phone service under a different homeowner, we don’t remove the battery backup.
9.If I try but can't locate the battery, what should I do?
Call us at 866-ETC-4YOU. We will check the battery remotely and schedule a technician to visit the home and replace the battery free of charge.
10.I can't find the battery backup and want one.
