Summary

Learn more about replacing the backup battery in your Cox Digital Telephone eMTA.

Solution

Your Cox Digital Telephone service utilizes telephone equipment that is connected to your home’s power. During a power outage, you will not have access to phone service or e911 unless a battery is installed in each piece of telephone equipment at your home. Backup batteries can provide up to eight hours of standby service or up to four hours of talk time using a corded telephone that does not require power and is directly connected to the telephone modem's jack. Cox recommends checking the battery status of your telephone equipment on a regular basis.
 

Batteries are available for purchase from Cox at any of our retail locations or when you order Cox Digital Telephone service.

You may have the option of installing the battery(ies) yourself or having a Cox technician perform installation of the battery(ies).  

If you choose to have the battery(ies) installed by a Cox Technician after installation of your Cox Digital Telephone service there will be an additional charge associated with the installation.

Refer to Important Information About The Use of Your Cox Digital Telephone Service During a Power Outage for more information.
