Few Customers Buy Batteries To Back Up VoIP, Cablevision, Charter Tell FCC

“The vast majority" of VoIP customers of Cablevision and Charter Communications don't buy batteries to back up the service when the power goes out, executives of the cable operators told FCC Public Safety Bureau officials, Charter said in an FCC filing. "Charter and Cablevision make significant efforts to educate their customers about the VoIP services they offer, including that such service will not work during a power outage without a backup battery." The filing was posted Tuesday in dockets including 14-174, which was related to an NPRM asking about "steps the Commission could take to safeguard continuity of communications throughout a power outage, including the possible adoption of new rules."
