Para leer esta información en Español consulte la sección Spanish Telephone Equipment Battery Questions and Answers.

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.
